• Forged torsion keys allow adjustable front height without sacrificing ride quality, keeping your truck comfortable on daily use and heavy loads.
• CNC-machined differential drop spacers are included for 4WD models to preserve proper driveline angles after the lift.
• Rear lift uses 2.0" cast iron blocks with longer U-bolts and hardware, designed for SRW 3500HD trucks with Tow Package leaf springs or dual rear wheels (DRW).
• Robust tie-rod end assemblies replace weaker factory joints to improve steering durability under load and during off-road use.
