Tire & Wheel Info

40 x 15.50 tire on standard offset wheel

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 Notes

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. Front driveshaft MUST be lenghtened

Optional extended length brake hoses recommended.

Rear brake hose included in kit box.

Brake line / hose relocating hardware included in kit box.

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.
