Prothane 4-218 Front Control Arm Polyurethane Bushing Kit

The Prothane 4-218 is a front control arm polyurethane bushing kit engineered for Chrysler LX-platform vehicles. Factory rubber bushings on these performance-oriented platforms are known for premature wear — with some reporting failures in as little as 20,000 miles — leading to vague steering, misaligned caster and camber settings, and degraded handling response. Prothane's high-performance polyurethane construction directly addresses these shortcomings.

Polyurethane delivers a significant durability advantage over OEM rubber: it resists degradation from oil, gas, and road chemicals while maintaining consistent compliance resistance over time. The result is sharper steering response, more precise alignment retention, and improved overall suspension feel without sacrificing ride comfort.

Key Features:

• High-performance polyurethane construction replaces failure-prone factory rubber bushings
• Superior compliance resistance maintains proper front suspension caster and camber geometry
• Impervious to oil, gas, and environmental contaminants for long-lasting durability
• Engineered specifically for the Chrysler LX platform front control arms
• Available in red or black — both share the same durometer (hardness) and performance characteristics
• Includes Prothane pre-lube for proper installation and noise prevention
• Lifetime warranty against defects in materials and workmanship for the original purchaser

Note: This kit does not include the bushing for the lower control arm strut connection point. For a complete LX platform polyurethane conversion, this kit pairs with Prothane 4-220 (rear control arm), 4-1140 (front sway bar), 4-1139 (rear sway bar), 4-702 (rack & pinion), and 4-109 (subframe).
