Will NOT fit models equipped with the Thermal Axle option (Reference build code DSK-P).
Will NOT fit Ram 1500 Rebel or Ram 1500 with Off-Road Group option.
Vehicles equipped with the Off-Road Group option require the Ram 1500 Rebel 4in kit to achieve correct ride height. To find out if your truck is equipped with the Off-Road Group, call your local Ram dealer, provide your VIN and ask if they can pull your window sticker. In the "Optional Equipment" section there will be a line item that reads "Off-Road Group" if your truck is equipped.
RAMs with factory 22" wheels require the larger bore knuckles due to larger wheel bearing assembly. Reference build code WPM or WPZ. Stock 20s can be reinstalled with factory tire size.
This kit will NOT work on Diesel models.
Does NOT work for models with factory rear airbag suspension.
IF USING 18IN WHEELS WITH MAXIMUM RECOMMENDED BACKSPACING, TEST FIT WHEELS ON VEHICLE BEFORE MOUNTING TIRES TO ENSURE CLEARANCE.
