SuperPro 84-89 Toyota 4Runner 2WD Rear Leaf Spring Shackle Bushing Kit

If you're working on the rear suspension of your 1984-1989 Toyota 4Runner, especially if you're looking to firm up the ride, replacing the leaf spring shackle bushings is a smart move. These often-overlooked parts play a big role in controlling how your rear axle moves. When the stock rubber bushings wear out, they can let the axle shift around more than it should, leading to a feeling of the rear end wandering or even a bit of passive steering, particularly when you're braking hard or carrying a load.

This kit from SuperPro uses well-built polyurethane bushings designed to offer more stability than the original rubber ones. Polyurethane holds its shape better and resists deflection, which helps keep your rear axle planted. This means a more predictable feel when driving, especially when towing or hauling. Upgrading these bushings can make a notable difference in how stable your 4Runner feels on the road, reducing that vague wandering sensation and improving control under load.
