Specs At A Glance

Good To Know

Q: Will this shackle lift change my pinion angle? A: The 1-1.5" lift may slightly alter the rear pinion angle; most trucks do not require driveline modification, but checking u-joint angles after installation is recommended.

Q: Can I install this kit without removing the leaf springs? A: Yes, the shackles can typically be replaced by supporting the axle and swapping one shackle at a time with basic hand tools, no spring pack removal needed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
