IMPORTANT DISCLAIMER: The provided tire/wheel fitments are approximate. Actual dimensions of a given tire size can vary considerably from one brand to another. Manufacturers' wheel offset and backspacing measurement points are not always consistent. Backspacing greatly impacts tire-to-fender clearance when turning. Wheel width and backspacing influence whether the tires protrude past the fenders, and to what extent. Considering these important factors, we recommend that you fit-check your tire/wheel selection prior to purchasing.

  • Installation time: 2 hours
  • Difficulty level: 2 of 5

Additional Info

1977.5-91 models require clearance (machining) of the front driveshaft CV cluster to prevent binding. If the vehicle has a single exhaust, the cross-over pipe requires modification to clear front driveshaft.

Optional extended length brake hoses recommended.

Brake line/hose relocating hardware included in kit box. Both driveshafts need to be lengthened.

This is a SwampRunner Series lift system that is intended primarily for off-road or exhibition use. Reference the "Important Product Use" section of the Warranty for additional safety-related information.

NOTE: If the vehicle is factory-equipped with auxiliary (dual) front shocks also order quantity two, part number 85150 Superide shocks.

NOTE: 88-91 Blazer/Jimmy and Suburban models require additional part number 315-88 bushing sleeve kit.
