Important Notes

Determine if your truck is equipped with standard (2-leaf main) or heavy payload (3-leaf main w/ overload) factory rear leaf spring packs. Standard 2-leaf main applications will require kit # F48; heavy payload 3-leaf main w/ overload applications will require kit # F50. See the "learn more" example image for reference.

Two-piece rear drive shaft? Add a carrier bearing drop kit to reduce post-lift driveline angles and avoid/eliminate driveshaft vibration. Fits SRW models only. 37x12.50 tires may require minor trimming. Factory wheels fit when paired with factory/original equipment tire size.
