Prothane 18-210 Front Control Arm Polyurethane Bushing Kit

The Prothane 18-210 is a polyurethane front control arm bushing kit designed as a direct upgrade over worn factory rubber bushings. Over time, OEM rubber control arm bushings stretch, flex, and sag under suspension load, causing the center sleeve to shift and throwing wheel alignment out of spec. Replacing them with Prothane's polyurethane bushings restores tight, predictable handling and helps maintain accurate caster and camber settings.

Key Features:

• Polyurethane construction — significantly firmer than OEM rubber, resisting the flex and deformation that leads to alignment drift
• Improved handling performance — reduces compliance deflection in the front suspension for more responsive steering feel
• Available in red or black — both colors are the same durometer (hardness) and perform identically; black formulation includes a small amount of graphite to further aid in noise reduction
• Includes Prothane Super Grease — supplied grease packet ensures proper lubrication during installation to prevent squeaking
• Made in the USA
• Lifetime warranty — Prothane guarantees this product against defects in materials and workmanship for the life of the original purchaser's vehicle

Note: Proper lubrication with the supplied Super Grease at installation is critical, as these are high-stress suspension components. For best results, thoroughly grease each bushing before pressing into place.
