AE86 Prothane Polyurethane Rear Control Arm Bushing Kit (1983-87 Corolla)

Prothane Polyurethane Rear Control Arm Bushing Kit

For 1983–1987 Toyota Corolla AE86 Trueno & Levin SR5, GTS and All JDM Trims

Overview

Restore the rear suspension of your AE86 with the Prothane Polyurethane Rear Control Arm Bushing Kit, engineered as a direct replacement for worn factory rubber bushings. Designed specifically for 1985–1987 Toyota Corolla AE86 rear-wheel-drive models, this kit helps reduce suspension flex, maintain proper rear alignment, and improve handling without altering factory suspension geometry.

Manufactured in the USA from Prothane's premium polyurethane, these bushings provide greater resistance to compression than conventional rubber while standing up to oil, grease, road salt, moisture, ozone, and UV exposure. By minimizing unwanted control arm movement, they help improve suspension precision, reduce wheel hop, and deliver more predictable handling during acceleration, braking, and cornering.

Whether you're restoring an original AE86 or upgrading your suspension for spirited street driving, autocross, drifting, or track use, Prothane rear control arm bushings provide long-lasting durability and improved chassis control.

Polyurethane vs. OE Rubber: Choosing the Right Bushing for Your Build

When deciding between polyurethane and factory rubber bushings for your restoration, it helps to weigh their performance traits: Polyurethane delivers a dramatic upgrade in handling precision, steering response, and cornering stability by eliminating suspension slop, alongside exceptional resistance to oil, road grime, and dry rot that ensures it will outlast stock rubber many times over. On the flip side, because polyurethane is a significantly firmer elastomer, it transmits a more direct, stiffer road feel and requires proper lubrication during installation (using the included super grease) to prevent squeaking. While OE rubber provides a softer, more isolated ride that absorbs minor road vibrations, polyurethane is the ultimate choice for enthusiasts seeking tighter handling, superior durability, and long-term performance from their classic build.

Available Color Options

Black Polyurethane

A factory-inspired appearance that blends naturally with OEM suspension components.

Red Polyurethane

Prothane's signature performance color for enthusiasts who prefer a more noticeable suspension upgrade.

Both colors utilize the same premium polyurethane formulation and provide identical fitment, durability, and performance. Color is the only difference.

Why Choose Prothane?

Prothane has been manufacturing high-performance polyurethane suspension components for decades. Unlike factory rubber bushings that soften, crack, and deform with age, Prothane polyurethane maintains proper suspension geometry under load while resisting environmental deterioration. The result is improved handling, more consistent alignment, reduced suspension deflection, and significantly longer service life.

For AE86 enthusiasts restoring an original Corolla or building a dedicated street, drift, autocross, or track car, Prothane rear control arm bushings deliver an ideal combination of durability, precision, and long-term reliability.
