What is the main benefit of upgrading leaf spring bushings?

Upgrading your leaf spring bushings helps to stabilize the movement of your rear axle. This can prevent the rear end from wandering, improve stability under heavy braking, and reduce unpredictable steering responses.

What material are these SuperPro bushings made from?

These bushings are made from a durable polyurethane material. Polyurethane offers a more controlled and stable response compared to the original rubber bushings.

Do these bushings come with greaseable shackles?

The manufacturer's description mentions upgrading to greaseable shackles for optimal performance, but this specific kit (SPF2240K) includes the shackle bushings. You may need to purchase greaseable shackles separately if your current ones are not already equipped.

Product Details

The polyurethane material in these SuperPro shackle bushings is a key upgrade for your 1984-1989 Toyota 4Runner's rear suspension. Often overlooked, these bushings play a critical role in controlling the movement of your rear axle. When the stock rubber bushings wear out, they can allow the solid rear axle to shift, leading to unpredictable steering responses, often called passive steer, and a general feeling of wandering down the road. This instability is even more pronounced when you're carrying extra weight or towing.

SuperPro's bushings are made from a durable polyurethane that offers a more controlled response than the original rubber. By upgrading to these, especially when paired with greaseable shackles, you'll notice a significant improvement in how your 4Runner handles. The rear end will feel more planted and stable, whether you're on the highway, carrying a load, or navigating rougher terrain. This kit is designed to help your rear suspension handle more demanding conditions than the original setup was intended for.
