- Heavy duty flat washers and hi-nuts included
Before installing a rear block
Rear block kits change the height of the axle relative to the frame, which can alter driveshaft angle and the position of the rear brake lines. Check the driveshaft angle and brake hose length after installation, and confirm the kit suits the leaf spring pack.
Leaf spring blocks are often installed with U-bolts that are re-torqued after a short drive. Reinspect the hi-nuts and washers after the first few trips and whenever the vehicle is driven on rough terrain. Look for shifting or spring wrap that could signal a loose mount.
- Confirm driveshaft angle after installation
- Check brake line length before driving
- Re-torque U-bolts after initial drives
- Inspect spring pad alignment during service
