Installation Notes
- Axle alignment shall be performed in accordance with SAE or TMC recommended standards.
- Installer must set the suspension to the specified mounting height before torquing the pivot bolt to prevent bushing pre-load.
- Pivot bolt must be torqued using a 1" drive impact wrench with E-20 Torx socket until the Torx head shears off.
- Customer-furnished crossmembers and filler plates are required.
- Suspension fasteners must be re-torqued at 6,000 miles and every 50,000 miles thereafter. Do not re-torque pivot fasteners.
- Axle-to-suspension welding must follow Ridewell Weld Process No. 1.
Maintenance Notes
- Inspect air springs, shocks, bushings, and fasteners during routine service intervals.
- Do not re-torque shear-type pivot fasteners.
- For bushing replacement, order Ridewell kit 6040098 and use installation tool 6100051.
Warranty Notes
- Failure to brace hangers for lateral loads voids the warranty.
- Stated capacity rating applies to suspension only.
