Trail Master suspension systems are uniquely designed to allow vehicles to take on the most extreme off-road trails, yet remain quiet and dependable for everyday driving. To do this, we design our systems to limit excessive wear and tear on factory ball-joints, steering components and reduce noise and vibrations. Making sure everything is durable and reliable is why our suspension systems include items such as, high-grade alloy steel- tube control arms, Flex-joint bushing technology, precision laser cut bolt-holes, CNC machined spindles, CNC press-brake formed brackets, and much more. Our suspension systems also come complete with everything required to properly raise your vehicle without having to order or purchase extra components. Find out why more people prefer a quality Trail Master Suspension, than other suspension kits on the market.



Great beginner lift

Overall a great low end cost lift for a jeep. Rides good. Great stance. Looks awesome. The only thing negative I have to say is that the kit could come with more hardware instead of having to reuse the factory bolts nuts etc. Would definetly purchase again.

Pretty Good

Overall its a pretty good kit. It flexes well. The main downside to this lift is the control arm bushings. They were totally shredded after two seasons. 4wheelparts informed me that they could be replaced with factory bushings I went with it because Trailmaster would not respond after months of attempts. Factory bushings will not fit these control arms.

2003 Jeep Wrangler/X with an existing 2" body lift on it. Saw on JeepForum where I guy added the 4" lift kit to the existing body lift for a 6" lift. Would this kit work in that application and would any additional parts be needed?
