Prothane 4-201 D50 2WD Front Lower Control Arm Bushing Kit 1979-1993

The Prothane 4-201 is a polyurethane front lower control arm bushing kit designed as a direct-fit upgrade over worn or deteriorated OEM rubber bushings. Engineered for D50 2WD applications from 1979 to 1993, this kit restores precise suspension geometry and helps maintain accurate front-end caster and camber alignment settings that soft, degraded rubber bushings simply cannot sustain.

Prothane's proprietary polyurethane formula delivers significantly greater compliance resistance than factory rubber, reducing unwanted control arm flex and movement under load. The result is sharper steering response, improved handling consistency, and a more connected feel between the road and the driver.

Key Features:

• Manufactured from high-durometer polyurethane for superior longevity over OEM rubber
• Optimized compliance resistance helps maintain proper front suspension caster and camber
• Direct-fit design for straightforward installation without modification
• Available in red or black — both colors share the same durometer rating and performance characteristics
• Includes Prothane Super Grease to prevent squeaking and ensure proper lubrication at installation
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship

Prothane polyurethane bushings are a proven performance upgrade over factory rubber components. Proper lubrication with the included Super Grease at the time of installation is essential for long-term, squeak-free performance.
