DJM Suspension Lowering kits is the leader in lowered suspension technology. When it comes to a comfortable ride for lowered trucks, suspension travel is the most important aspect to consider and the most difficult to achieve. All DJM lowering kits and components are designed to give you maximum drop without losing suspension travel which will alter the ride. Limited Lifetime Warranty. The best quality and craftsmanship starts in DJM's R&D department. Prototype parts are designed and built, then tested over and over. Changes and improvements are made throughout the complete process. This process continues until a part is designed that is easy to install, fits into original equipment locations (no modification) and has no clearance problems with the wheels or any part of the truck. DJM uses an alignment rack during prototyping to insure that all of their kits are fully alignable. DJM Drop Kits should be aligned to factory specifications to optimize performance and handling. A test vehicle is then driven daily by DJM engineers in all normal driving conditions to determine the long term effects on the parts. Thousands of miles are racked up during this phase and that's what it takes. That's the DJM difference, the latest designs with the highest quality product and prices, almost too good to be true. ALL SUSPENSION KITS HAVE SHOCKS SOLD SEPERATLEY.
