Lowered trucks handle better, look better and, when lowered correctly with properly engineered and quality matched components, they ride nice as well!

DJM Suspension has thought of everything for this kit! New Drop Spindles, Axle Flip Kit and everything you need to get that perfect ride height! This kit is ready to go out of the box and installs in the factory location

This kit will require you to C-Notch your frame as this is the best way to drastically lower the rear end of your truck. Support brackets are included to reinforce your frame as well as DJM’s adjustable axle brackets.

*Note: With lowering your vehicle 5 inches or more we recommend replacing your front shocks with 1361415 and 1361800 for driver rear and 1361900 for passenger rear. The shock extenders correct the shock angle so they function properly and centers the rear axle.
