Y62 Patrol – Airbag Kit – AAA Suspension – Coil Delete

The AAA Coil Delete Kit is a suspension upgrade designed specifically for all Y62 Patrol models. Manufactured in Australia and backed by our extensive 4WD expertise, this kit ensures constant ride height with excellent comfort and superior handling regardless of load or terrain.

Imagine this: you’re fully loaded and towing your caravan across the Simpson Desert. Your vehicle’s ride height remains perfectly level, just as it was when you were driving to the shops back home. There’s no unnecessary tyre wear, and the ride is still smoother and more comfortable than the factory setup.

Why Choose the AAA Coil Delete Kit?

1. Constant Ride Height:
   Achieve a consistent ride height no matter the load—whether towing a caravan, carrying passengers, or driving unloaded it’s always the same height. Unlike heavy coils, this system maintains optimal alignment, improving handling, fuel economy, and tire longevity.
2. Softer Ride:
   Provides a softer-than-factory ride without sacrificing the ability to handle the heaviest loads. Perfect for towing or off-road touring. If you have been quoted heavier coils – ask how they propose to make heavier coils soft again when not loaded or towing… the point is they can’t. Only air bags can have varied load abilities.
3. Improved Performance:
   Experience enhanced stability even in tough off-road conditions. When your wheel alignment is out the wearing out of tyres is because they are scraping sideways along the road so you don’t really have that much traction. By maintaining wheel alignment you optimise safety through added traction as well as save your tyres.
4. Peace of Mind:
   AAA Coil Delete don’t sag under extreme loads like heavy coils with inserts still do. And they won’t sag over time.
   Not prone to leaking or falling apart like coil inserts do.
   Your investment is protected by AAA rated 10 year warranty even against leaks and all parts can be purchased individually if you want a spare part or need support beyond warranty period.

AAA’s auto levelling system:

Our Auto Ride Height Kit features pneumatic valves as used in the truck industry. A valve body is mounted to the chassis K frame on each side using the hand brake cable bolt so no drilling required. There’s a swing arm that’s attached to your lower rear control arm. It senses the height over a given wheel. When too low (loaded) the arm position lets air into the bag on that side and it inflates. When too tall (unloaded) the arm lets air out of the bags. The whole system is entirely automated which is how the engineers like it. There’s a tolerance in the middle which allows minor up and down such as discrete road undulations and corrugations etc without inflating or deflating occurring. There is an adjustable link rod the installer can lengthen and shorten so you can set your ideal ride height on each side. And it’s at that position you get your wheel alignment done.

GVM Upgrade Options:

The operational aspect of the AAA kit is approved in its complete form. All the critical components used in this kit have undergone specific engineering testing. Not just the bags but also the control arms, the tanks, the duty cycle of the compressor along with swerve and brake testing. As such the kit has to be fitted the way we specify in the instructions, components can not be left out nor be substituted. These tests have been documented and registered nationally so engineers all over Australia can rely upon these and not have to do the testing themselves.

You need to appoint an engineer – we have one in Vic and can assist with interstate recommendations. We can supply the necessary documentation and the engineer will need to see your car on a hoist to check it out and take pics. Shortly after you receive your blue plate and engineer sticker in the mail with instructions where to fit. Then you book the car in with your state’s road registration authority for them to check and finalise the upgrade.

We offer 3830 Kg GVM by doing just the rear with this coil delete kit. By also doing heavier coils and upper control arms in the front we can increase this to 4000 Kg. Refer to pricing below which spells out what’s involved for each. Neither require tyre or wheel upgrades. It is available in all states and transferable between states.  GCM is currently not available.

Large Twin-Head Compressor:

AAA’s large CX10 Twin Head Compressor is 10 x faster than its smaller predecessor and excellent at inflating tyres or blowing dust out of the vehicle and generates less noise too. The CX10 comes with mounting hardware and sits vertically behind the grill next to the left side headlight. It doesn’t impact air flow and fits with or without a bull bar or winch.

Integrated Air Tank:

When lowered the sensors call for air and that could even be a momentary hard dip in the road. Rather than trigger the compressor for a split second it’s better to have the air come from a tank. With a tank the compressor only starts periodically to recharge the tank and coupled with our large CX10 compressor that only takes about 2 seconds.

4WD Mode:

AAA have developed a patch harness that plugs to the back of the 4WD switch in the Centre Console. Coupled with a Change Over Relay and electronic valves the air to and from each of the bags can is blocked when 4WD Hi or Lo is engaged. Now you can tackle the ruts or undulating beaches without the auto ride height trying to compensate all the time. By its very nature this is 4WD Use Only. When you go back to 2WD the valves re-open and the auto ride height system is live again. Rather than an add on it meant a different way we set things up so it is now a part of every kit we sell.

Braced Factory Lower Control Arms – LCA:

The base kit comes without lower control arms as it bolts to factory arms as well as billet arms. The plate spans almost the entire length of the arm so we have never ever had a factory arm suffer with our coil delete kit. If you are not seeking a GVM upgrade then not getting our LCA is an opportunity to save money. GVM upgrades do require LCA upgrade and so it’s an option when you check out. At factory height or no lift the LCA you need can be these Braced Factory Arms. If you are running a 2″ lift then you need our Extreme Duty Arms (below)

Extreme Duty Lower Control Arms – XDLCA:

If you are going for a 2″ lift then you need AAA’s Extreme Duty LCA. These have undergone final engineering, are now in production and will be ready for sale in February 2025.

When the Y62 is lifted to 2” the rear hub rotates backwards and causes the LCA to lean to the back. Pushing down from above onto an arm that already has a lean backwards can force the arm to lean even further and create problems with bushes. It’s a situation only prone to 2″ lifted vehicles but even then it’s only the heavier ones and only in rugged pounding terrain. Not every 2″ lifted rig has the problems – its a bit like smoking – not everyone gets lung cancer but it tends to be the smokers who do.

These lifted rigs that are heavy need the bags more than anyone else so it’s a market we needed to accommodate. Enter from stage left – AAA’s Extreme Duty Lower Control Arms for 2″ lift.

The LCA needs to compensate for the arm to be leaning upwards with a lift and also needs to factor in the caster rotation. The AAA Extreme Duty LCA not only factors the caster tilt back to being level but moves the bottom of the air bag to below the magic line between inner and outer bush and as such is no longer pushing down from above but now pulling down from below – a bit like a hammock. A new set of top mounts accompany the Extreme Duty LCA. Plus an added bonus outcome the bag is shorter (less tall) at 2″ lift so it is even softer than before.

If you already have a Coil Delete kit we can supply and instal a set of XDLCA as an upgrade.

Note because some people want nothing but the very best we are also going to launch these for non lifted factory height as well.

Braided Lines:

The kits now come with braided lines at both bags as well as a h/d duty 300 psi rubber air line from compressor at the front of car to the tank at the rear. This mainly prevents the impact of heat from the exhaust on the driver side, heat generated by the compressor and also stones or debris off the trails. In March 2025 we are releasing a complete braided line kit available to everyone that eliminates all plastic, PU or Rubber hose.

Side Clearance Indicators for GVM:

If you are seeking a GVM you might need ADR compliant Cat 6 side clearance indicators. All 4,000 GVM need them and 3830 GVM needs them unless they have 8 seats (yep – a crazy loop hole). The concept being that heavier vehicles tend to be longer and other vehicles in lanes beside you need to see that you are indicating. With a GVM upgrade we are no longer than normal so makes no sense but it’s the rules. They need to be Cat 6 type which means clear lens but shine amber when on. Some towing mirrors have them and some older mirrors have Cat 5 which can be upgraded to Cat 6. We stock clearance lights for the front guard if required and they are listed as an option when you check out.

Durability You Can Trust:

Our air bags have been installed in thousands of Y62 Patrols and 4WD vehicles, covering millions of kilometres in Australia’s toughest environments—without a single puncture. It’s reassuring to know you can plug a puncture with a tyre string and AAA will replace it when you get home under their 10 year warranty program but for what it’s worth – it is yet to happen.

Installation:

The AAA Coil Delete Kit is designed for bolt-on installation using existing factory mounting points. No drilling, cutting, or welding is required, making it a straightforward upgrade. We have workshops in most states. Workshops allow 14 hours for installation. We make the assumption the installer has a hoist, a mechanical aptitude, a basic knowledge of how relays work and most importantly read and follow instructions.

Prices:

In our workshop an installation takes 2 full days and is priced as follows:

Base Kit:

• $4,000 – Base Kit (incl. auto level, tank, large compressor & 4wd mode).
• $2,100 – 14 Hours Fitting @ $150/hr
• $225 – Wheel Alignment

          $6,325 – Sub Total Cost for Drive-away price with no GVM.

 

3830kg GVM (Rear axle GVM upgrade only):

• $1,400 – Braced Factory Lower Control Arms (after a $350 rebate for change over).
• $1,750 – GVM Engineering
• $400 – Cat 6 Side Clearance Indicators (not required if 3830 GVM and 8 seats) Includes fitting

          $9,875 – Sub Total Cost for Drive-away price with 3830kg GVM.

 

4000kg GVM (Front axle GVM upgrade):

• $1,250 – Front Coils & Upper Ctrl Arms
• $900 – 6 hours to fit front – includes HBM work and note we even need to remove power steering pump to get bolts out for upper control arms

• $750 – additional engineering GVM codes

          $13,700 – Sub Total Cost for Drive-away price with 4000kg GVM.

Other prices:

• $400 – Interstate GVM documentation (Available for 3830 Kg and soon 4000 Kg) – we are waiving this for February 2025 orders
• $220 – We totally suggest replacing your factory wheel alignment cam pins to locking cam pins. The cam Pin is an off set bolt and when rotated it lengthens or shortens an arm – it is how your wheel alignemnt adjustments are done. The Y62 is prone to go out of alignment all on its own by hitting bumps and these cam pins rotate. We can now supply you with locking cam pins that hold fast and maintain your alignment. There are 4 cam pins in the rear and they are only $55 each.

Wheel Allignment:

A job like this demands a good wheel alignment to be done straight away. We arrange this when we fit the kit and totally suggest you get this done if you are getting this fitted elsewhere. Especially when changing ride heights.

Passionate About Patrols:

At AAA Suspension, our passion for Nissan Patrols runs deep. Within our team we race three off-road race Patrols. Steve’s GQ was among the very first to have a LS1 conversion when it was just 4 years old and guess what – that project involved Andy (now On Track) and Mark French (Mark’s Adaptors) so our connections go way back. Steve runs the Cliffhanger 4×4 Event and Justin runs the Ultimate 4×4 Challenge and with Jason we’ve collectively competed in about 25 Outback Challenges—all in Patrols. You’d be hard-pressed to find a team more dedicated and experienced with Patrols in the industry. Our firsthand experience ensures that you’re getting products developed by enthusiasts who truly understand your needs.
