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.



Looks amazing

Just got the lift installed and it looks and drives GREAT. Only issue I had with the lift is that the instructions were a little off for some things. They tell you to re-use the front sway bar links but they're too short, so wound up using the old rear ones. Nothing too bad just left you scratching your head sometimes. Other than that I've got 0 complaints.

Does this kit require drive shaft mods and what other mods will need to be done? Thanks Troy

Asked by DWB from Elmendorf, tx on

Hello, if you are planning on off roading the Jeep then you should replace the drive shafts with heavy-duty drive shafts. If you are just lifting it for looks and it's staying a street driven machine with maybe some easy off road trails you can use the stock drive shafts still. They are not strong enough to handle any severe off road punishment they will twist and bend. Thank you!

Since the late 1980's Trail Master Suspension has been a trusted name in the off-road industry for suspension components that will get the job done at a reasonable price. Trail Master produces off-roading full suspension systems, shock absorbers, leveling kits, steering stabilizers and accessories for a variety of trucks, Jeeps and SUVs. Trail Master designs its products for the hardcore off-roader but at a price point for the weekend-warrior. Each complete suspension system is designed for and tested on each individual vehicle application, as are the leveling kits. To accompany its lift kits and leveling kits Trail Master has its own line of SSV shock absorbers meant for off-road use with extra wheel travel and fade free performance. Shop Trail Master Now
