Description
All-Pro’s Rear Long Travel Leaf Springs are 9 inch longer than factory (1979-1988) rear springs. Mounting these longer springs will require new front spring hangers and relocation of the rear shackle hangers on pre-1989 trucks. Our rear springs have 8 leaves, plus a special torque leaf to reduce axle wrap. Springs come with new poly bushings. We do not have stock length rear springs available.
When installing the same lift onto a 4Runner, the rear springs will need to be 1 inch-2 inch taller than the front to compensate for the added weight of the vehicle. 1984-1989 4Runners weigh an average of 700lbs more than the pickup because of the hardtop, glass, interior components, roll bar, heavier tailgate and power window assembly inside, and other components. If you always run your 4Runner empty in back, a 1 inch taller rear spring will generally be enough to level it with the front. If you carry spare parts or extra passengers in back we recommend a 2 inch taller spring than the front.
Note: These springs are not designed for weight carrying capability. They are designed for ride quality and flex. If you intend to use the vehicle for carrying weight, we recommend adjusting the bump stops to prevent bottoming out and damaging the shocks or springs and adding airbags or other support devices.
