Installation Notes
- Axle alignment must be performed in accordance with SAE or TMC recommended standards.
- Set the suspension to the specified mounting height before torquing the pivot bolt to prevent pre-loading the bushing.
- Install the anti-turn washer over the eccentric bolt head and weld after final axle alignment.
- Suspension fasteners must be re-torqued initially at 6,000 miles and again at 50,000 miles.
- Axle-to-suspension welding must follow Ridewell Weld Process No. 1.
Maintenance Notes
- Inspect suspension components, air springs, and fasteners during regular service intervals.
- Re-torque suspension fasteners at specified mileage intervals.
- Inspect pivot bushings and wear washers and replace as required.
Warranty Notes
- Suspension systems are warranted to be free from defects in material and workmanship when properly installed and maintained.
- Warranty coverage is limited to repair or replacement of suspension components.
- Warranty is non-transferable and excludes incidental or consequential damages.
