Prothane 18-208 Polyurethane Control Arm Bushing Kit - MR2 1985-1989

The Prothane 18-208 is a polyurethane control arm bushing kit engineered as a performance upgrade over worn factory rubber bushings. Prothane's polyurethane construction is significantly firmer than OEM rubber, which helps resist deflection under load and keeps the control arm geometry precisely where it belongs — preserving your alignment settings and delivering more predictable handling.

Over time, stock rubber control arm bushings stretch and flex repeatedly as the suspension cycles. The center sleeve gradually sags, throwing alignment out of specification until the rubber fails entirely. Replacing them with Prothane's polyurethane eliminates this degradation and restores suspension precision.

Key Features:

• High-performance polyurethane construction — firmer than OEM rubber for improved compliance resistance and handling response
• Available in red or black — both colors share the same durometer (hardness); black includes a small amount of graphite to assist with noise reduction
• Includes Prothane Super Grease — proper lubrication at installation prevents squeaking on this high-stress suspension component
• Includes metal sleeves for correct fitment and load distribution
• Made in the USA by Prothane, a trusted name in polyurethane suspension components
• Lifetime warranty against defects in materials and workmanship for the original purchaser

Kit Contents:

• 4x Control Arm Bushings (Part #64309)
• 2x Metal Sleeves (Part #60659 — 3/4" x .482" ID x 2.345")
• 2x Prothane Super Grease packets (Part #19-1750-001)

A press may be required to remove the original bushings. Thorough lubrication with the included Super Grease is essential during installation to ensure long-term, squeak-free performance.
