Prothane Polyurethane Front Control Arm Bushing Kit (1986-95 4Runner)

Prothane Polyurethane Front Control Arm Bushing Kit

For 1986–1995 Toyota 4Runner 4WD and 1990–1995 U.S.-market 4Runner 2WD

Overview

The Prothane Polyurethane Front Control Arm Bushing Kit replaces worn factory rubber bushings in the front upper and lower control arms of 1986–1995 Toyota 4Runner 4WD and 1990–1995 U.S.-market 4Runner 2WD models. The firmer polyurethane construction helps reduce unwanted control-arm movement and maintain more consistent suspension geometry, steering response, and alignment.

Toyota used two different front control-arm bushing configurations across this year range, so the correct kit must be selected by model year: 1986–1988 or 1989–1995.

Key Features

• Polyurethane replacement for factory rubber control-arm bushings
• Services the front upper and lower control arms
• Covers both driver and passenger sides
• Two model-year-specific configurations
• Helps reduce suspension deflection under braking and cornering loads
• Helps maintain more consistent caster and camber settings
• Polyurethane installation grease included
• Available in black or red
• Installs in the factory bushing locations

Polyurethane Control Arm Design

Factory rubber control-arm bushings soften and deteriorate with age, allowing additional control-arm movement under suspension load. Polyurethane provides a firmer pivot point that helps the front suspension maintain more consistent alignment geometry while still allowing normal control-arm articulation.

Black and red bushings have the same hardness and performance; color is a preference rather than a stiffness choice. Polyurethane can transmit more noise and vibration than factory rubber.
