How to Fit a Load Assist Kit on a VW Amarok (2026)
Fitting a load assist kit on a VW Amarok is a bolt-on job most owners can finish in an afternoon with basic hand tools and a vehicle hoist or quality axle stands. This guide walks through the fitment process for the current-generation Amarok, built on the Ford Ranger platform from 2023 onward, step by step.
- The load assist kit VW Amarok owners need for the 2023+ next-gen model bolts in without drilling in most cases.
- Boss Air Suspension supplies this kit in up to 2 inch lift and greater than 2 inch lift versions - match it to your suspension height.
- Budget 2 to 4 hours per side with a hoist; longer on stands. Buy the correct lift-height variant first.
- Air pressure is adjustable from empty to full load - never guess, check the pressure once the vehicle is loaded.
Why this matters
A new-generation Amarok with a canopy, tools, water and a loaded tray sits noticeably lower at the rear, especially when towing. That sag isn't just cosmetic - it reduces ground clearance, throws headlights out of alignment, and makes the rear suspension work harder over corrugations and speed humps.
A load assist kit doesn't add payload capacity or change your GVM. What it does is work with the Amarok's existing rear suspension to help control that sag and keep the vehicle sitting more level when loaded. That's a meaningful difference for anyone running a canopy, tray tools or a caravan behind a 2023+ Amarok.
Getting the fitment right the first time avoids two common outcomes: airbags that rub on the coil spring coils, and air lines that get pinched under load. Both are avoidable with a careful install.
What you'll need
- Load assist kit matched to your Amarok's ride height - the load assist kit for Ford Ranger 22 / VW Amarok 23 next-gens up to 2 inch lift suits a standard-height or up-to-2-inch-lifted rear end
- Vehicle hoist or two axle stands rated for the Amarok's rear axle weight, plus a trolley jack
- Socket set (metric), torque wrench, and a spring compressor if your workshop uses one for coil removal
- Silicone lubricant or soapy water for seating the airbag against the coil
- Thread sealant for air fitting connections
- A tyre inflator or compressor with a gauge for the initial pressure test
- 60 to 90 minutes per side if you're comfortable with basic suspension work; longer for a first-time install
If your Amarok already has a rear suspension lift greater than 2 inches, the standard kit won't clear correctly - check the load assist kit for Ford Ranger 22 / VW Amarok 23 next-gens greater than 2 inch lift instead. Confirm your exact lift height before ordering - fitting the wrong variant is the single most common return reason for this category.
The steps
1. Confirm fitment before you touch a spanner
Measure your actual ride height rather than relying on memory of what was fitted. A 2 inch lift kit that's settled slightly, or an aftermarket spring swap, changes which Boss Air Suspension kit variant clears correctly.
Common mistake: ordering based on what the suspension shop told you two years ago rather than what's measured on the vehicle today.
2. Raise and support the rear of the Amarok
Raise the rear axle until the wheels are just off the ground and support the chassis on stands rated for the job, never the jack alone. This gives the rear coil springs room to droop and opens up the working space you need around the spring.
Expected outcome: the rear coil spring should have enough travel that you can see the full coil without the tyre in the way.
3. Remove the wheel and inspect the coil spring cavity
Pull the rear wheel and take a good look at the coil spring seat, the shock mount, and any brake lines or ABS sensor wiring routed nearby. Every kit is designed around the factory spring geometry, but a visual check now avoids surprises later.
Common mistake: skipping this inspection and later discovering a wiring loom sits exactly where the air line needs to run.
4. Fit the mounting brackets
Most load assist kits locate using the coil spring itself or existing mounting points, so this step is usually bolt-on without drilling. Torque brackets to the fastener manufacturer's spec, not by feel.
Expected outcome: brackets sit flush with no gap, and the coil spring isn't distorted by an over-tightened bracket.
5. Install the airbag inside the coil spring
Lubricate the airbag with soapy water so it seats without twisting, then centre it inside the coil. A twisted airbag sits under uneven load and wears faster - take the extra minute to get this right.
Common mistake: forcing the airbag in dry, which can cause it to bind against the coil and inflate unevenly.
6. Run the air line and fit the inflation point
Route the air line clear of moving suspension components, exhaust heat, and anything with a sharp edge. Secure it every 150-200mm with a cable tie or clip so it can't chafe against the chassis or drop onto the tailshaft.
Decide here whether you're running a simple valve stem for manual inflation or stepping up to an in-cab digital controller - more on that below.
7. Pressure-test before you lower the vehicle
Inflate each airbag to a low test pressure - around 10-15 psi - and spray the fittings with soapy water to check for bubbles. A slow leak at this stage is far easier to fix on stands than once the Amarok is back on the ground and loaded.
Expected outcome: no bubbles at any fitting, and both airbags inflate evenly to the same pressure.
8. Set ride height and air pressure for your load
Lower the vehicle, load it as you normally would - tools, canopy, water, or hitch up the van - and adjust pressure until the rear sits level again. Boss Air Suspension airbags are designed to be adjusted between empty and full load rather than run at one fixed setting.
Common mistake: setting pressure once when empty and never adjusting it again when towing or carrying a heavier load.
Troubleshooting
- Airbag rubs against the coil spring - usually means it wasn't centred during fitting. Deflate, reseat with lubricant, and recheck alignment before reinflating.
- Slow air leak at a fitting - re-check the fitting with thread sealant and retighten. A leak that reappears after resealing points to a damaged O-ring.
- Vehicle sits higher on one side - check both airbags are inflated to the same pressure. A 5 psi difference side to side is enough to cause a visible lean.
- Air line rubs through over time - re-route away from the tailshaft and secure with additional clips. This is more common on Amaroks with aftermarket exhaust systems that sit closer to the line's original path.
- Ride still feels soft under a heavy load - the airbags may need more pressure than the empty-vehicle setting. Increase in small increments of 5-10 psi and recheck ride height.
- In-cab gauge reads inconsistent pressure between bags - check for a pinched line or a loose connection at the manifold before assuming the gauge itself is faulty.
Tools and resources
- Airbag fitting kit - covers the brackets, air line and fittings most installs need beyond what ships with the airbag kit itself
- Boss Auto Pressure Controller Kit with PX06 Compressor, 9L tank, fittings, water trap and Nitto coupling - for owners who want in-cab pressure adjustment rather than a manual valve stem, this pairs the compressor, tank and controller in one kit
- A digital tyre gauge accurate to 1 psi - the difference between a level Amarok and a lean often comes down to a few psi
- Your Amarok's owner's manual for factory tyre and load specifications
What to do next
Once the load assist kit is fitted and pressures are set, the next practical step for most Amarok owners is sorting out a towing setup - weight distribution, tow ball download and trailer brake checks all interact with how your rear suspension behaves under load. The guide on air bag suspension for towing caravans - setup and tips covers that in more detail.
FAQ
What load assist kit fits a VW Amarok in 2026?
The current-generation Amarok (2023 onward) shares its platform with the Ford Ranger, so it uses the same load assist kit fitment - available in up to 2 inch lift and greater than 2 inch lift versions depending on your ride height. Older Amarok generations need separate confirmation of fitment.
Do I need to drill holes to fit a load assist kit on a VW Amarok?
Most load assist kits for the Amarok bolt onto existing mounting points and locate inside the factory coil spring, so drilling isn't typically required. Always check the specific kit's fitting instructions before starting.
Will a load assist kit increase my Amarok's GVM or towing capacity?
No. A load assist kit helps manage rear-end sag and improves stability under load, but it does not change your Amarok's legal GVM or towing capacity unless paired with an approved GVM upgrade.
How long does it take to fit a load assist kit on a VW Amarok?
Budget 2 to 4 hours for both sides if you're using a hoist and have basic suspension experience. On axle stands, or for a first attempt, allow closer to half a day.
What air pressure should I run in my Amarok's load assist airbags?
There's no single correct pressure - it depends on your load. Start around 10-15 psi empty and increase in 5-10 psi steps once loaded until the rear sits level, checking with a proper gauge each time.
Can I fit a load assist kit myself or do I need a mechanic?
Many owners fit these kits themselves with basic tools and a hoist or stands, since most installs are bolt-on. If you're not confident working under a raised vehicle, a suspension specialist can fit it in under an hour with the right equipment.
Does a load assist kit work with my Amarok's existing suspension?
Yes. A load assist kit is designed to work alongside the factory coil spring rear suspension, not replace it - the airbag sits inside the coil to add adjustable support when the vehicle is loaded.
One last thing
The most overlooked step in any load assist kit install isn't the fitting - it's checking pressure again after the first loaded trip. Coil springs and airbags settle slightly in the first few hundred kilometres, so a pressure that looked level in the driveway can drift a few psi once everything's bedded in. A five-minute recheck after week one saves a callback later.
