Rear Leaf Spring Bushings Prothane Polyurethane

Description

Product Overview

Prothane’s rear leaf spring bushings are engineered for the demanding environment of rear suspension systems. Constructed from high‑grade polyurethane (PU), these components deliver exceptional wear resistance, low friction, and a smooth ride. The kit includes both rear eye bushings and shackle bushings, each precision‑fabricated to match OEM specifications (model 18‑1002‑BL). With dimensions of 4 × 4.5 × 3 inches and a weight of just one pound, the bushings are lightweight yet robust, ensuring a perfect fit without the need for additional modifications.

Usage

Designed for a wide range of vehicles, these rear spring bushings are ideal for trucks, SUVs, and performance cars that require enhanced rear suspension stability. Whether you’re tackling daily commutes, off‑road adventures, or track days, the polyurethane material absorbs shocks and minimizes metal‑to‑metal contact, extending the life of your leaf springs. Install the bushings during routine maintenance or as part of a performance upgrade to experience quieter operation and improved handling.

FAQ

What vehicles are compatible with these bushings?

The Prothane rear leaf spring bushings are compatible with most trucks, SUVs, and performance cars that use standard rear leaf spring eye and shackle mounting points. Check your vehicle’s service manual for the exact part number (18‑1002‑BL) to confirm fit.

Do I need special tools to install the bushings?

Installation typically requires basic hand tools such as a socket set, pry bar, and a bushing press or hammer. For best results, follow the included installation guide or consult a professional mechanic.

How does polyurethane compare to rubber bushings?

Polyurethane offers higher tensile strength, better resistance to oil and chemicals, and a longer service life than standard rubber. It also provides a firmer ride with reduced sag, making it ideal for performance‑oriented applications.

Will these bushings affect ride comfort?

While polyurethane is stiffer than rubber, the design balances rigidity with flexibility, maintaining comfortable ride quality for everyday driving while improving handling under load.

Are the bushings covered by a warranty?

Yes, Prothane provides a limited warranty against manufacturing defects. Refer to the warranty card included with the product for full details.
