Gremeltech Air Helper Kit – Jeep Grand Cherokee WK/WK2 (excl. SRT-8) (2005–2011)

Short Product Summary

A vehicle-specific Gremeltech air helper kit for the Jeep Grand Cherokee WK/WK2 (excl. SRT-8) (2005–2011). It adds adjustable air support to the rear suspension, working alongside the factory coil springs, so the vehicle sits level when you are towing or carrying a heavy load.

Why This Product

Hook up a caravan or load the back with a canopy, drawers, water and gear, and the rear of the vehicle drops. The nose lifts, the headlights point up and the vehicle feels less settled. An air helper kit props the rear back up, and you set the air pressure to match the load: more when towing or fully packed, less when you are running empty.

Key Features

• Made for the Jeep Grand Cherokee WK/WK2 (excl. SRT-8) – a vehicle-specific Gremeltech kit for 2005–2011
• Adjustable air pressure – set the support to suit the load you are carrying
• Reduces rear-end sag – keeps the vehicle sitting level under load
• More stable under load – improved stability and handling when towing or fully packed
• Works with your factory coil springs – the kit supports the existing springs rather than replacing them

Ideal For

• Towing a caravan or off-road trailer behind your SUV or 4x4
• Overland builds with a long-range tank, fridge, drawers and recovery gear in the back
• Family trips with a full load of people and luggage
