Installation Notes

  • Axle alignment must 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 an E-20 Torx socket until the Torx head shears off.
  • Welding of adjuster plates or alignment washers to the hanger is not required or recommended.
  • 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.
  • Customer-furnished crossmembers and filler plates are required.

Maintenance Notes

  • Inspect air springs, shocks, bushings, and fasteners during routine service intervals.
  • Do not re-torque shear-type pivot fasteners.
  • Replace bushings using Ridewell-approved replacement kits as required.

Warranty Notes

  • Suspension systems are warranted to be free from defects in material and workmanship when properly installed and maintained.
  • Stated capacity rating applies to suspension only. Axle, brake, and wheel end ratings are per their manufacturers.
