Prothane 4-214 Front Control Arm Polyurethane Bushing Kit

The Prothane 4-214 is a front control arm polyurethane bushing kit designed as a direct-fit, performance upgrade over worn or deteriorating factory rubber bushings. Worn OEM rubber bushings allow excessive control arm movement, making it nearly impossible to maintain precise front suspension caster, camber, and toe settings—leading to vague steering, accelerated tire wear, and unpredictable handling.

Key Features:

• Premium Polyurethane Construction: Engineered from high-performance polyurethane for greater durability and resistance to wear compared to stock rubber bushings
• Superior Handling: Provides optimum compliance resistance to keep control arms firmly located, improving steering response and overall suspension precision
• Alignment Integrity: Maintains accurate caster, camber, and toe settings by eliminating bushing flex and deflection
• Includes Super Grease: Kit ships with Prothane's supplied Super Grease for proper lubrication during installation—essential for quiet, long-lasting operation
• Made in the USA: Manufactured domestically to Prothane's high quality standards
• Lifetime Warranty: Backed by Prothane's lifetime warranty against defects in materials and workmanship for the original purchaser
• Available in Red or Black: Both colors share the same durometer (hardness); the black variant includes a small amount of graphite which may further reduce squeaking

Installation requires pressing out the OEM rubber bushings and pressing in the new polyurethane bushings using the supplied grease. Prothane's precision-fabricated design ensures a proper fit with no modifications required. This kit is a direct replacement for the front control arm bushings and is the preferred choice for performance enthusiasts and daily drivers looking to restore or improve front-end feel and alignment stability.
