Designed for Trail Boss and AT4 owners who want additional ride height and tire clearance, this Fabtech Upper Control Arm lift kit raises the front 1.5" to allow full-size 33" tires on 18" or 20" wheels. These models come from the factory with a 2" lift; adding this 1.5" kit results in a stance comparable to a standard model with a 3.5" lift while maintaining proper suspension articulation.
The kit includes premium stainless steel Dirt Logic coilovers and shocks engineered for corrosion resistance and long service life. The front Dirt Logic 2.5 coilovers feature a stainless steel body and NitroSteel piston rod for superior durability and smooth on- and off-road performance. The rear Dirt Logic 2.25 shocks share the same stainless construction and provide excellent damping for varied terrain.
Tubular upper control arms with heavy-duty ball joints correct front suspension geometry at the new ride height, allowing proper alignment and ride quality. Thanks to updated GM suspension geometry, no differential drop brackets are required for CV axle operation.
Rear lift is achieved with 1" blocks and U-bolts; some owners choose to omit the rear blocks to achieve a level stance. The kit is reversible so the suspension can be returned to stock if desired.
