Installation Notes
- Axle alignment shall be in accordance with SAE or TMC recommended standards.
- Installer must set the suspension to the specified mounting height before torquing the pivot bolt.
- After axle alignment, install the anti-turn washer over the eccentric bolt head and weld to the hanger.
- Main suspension fasteners must be re-torqued initially at 6,000 miles and every 50,000 miles thereafter.
- Axle-to-suspension welding must follow Ridewell Weld Process No. 1.
- Failure to brace hangers for lateral loads voids warranty.
Maintenance Notes
- Inspect suspension structure, air springs, shocks, and fasteners during routine service intervals.
- Inspect pivot bushings and wear washers and replace if excessive wear is present.
Warranty Notes
- Suspension systems are warranted to be free from defects in material and workmanship when properly installed and maintained.
- Warranty applies to the suspension only.
