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.

1977.5-91 models require clearancing (machining) of the front driveshaft CV cluster to prevent binding. If vehicle has 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.

88-91 Blazer, Jimmy, and Suburban require additional sleeve kit part # 315-88.

The kit is packaged complete with Superlift Superide shocks.

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