Prothane 7-274-BL GM Front Lower C-Arm Bushing Kit Black Polyurethane

The Prothane 7-274-BL is a black polyurethane front lower control arm bushing kit engineered as a high-performance upgrade over factory rubber bushings on GM vehicles. Worn or soft OEM rubber bushings allow the control arm to shift and flex under load, resulting in imprecise steering, inconsistent handling, and difficulty holding accurate alignment settings. Replacing them with Prothane's polyurethane bushings restores proper suspension geometry and significantly improves chassis response.

Key Features:

• Black polyurethane construction — firmer than OEM rubber for improved compliance resistance and reduced control arm deflection
• Superior handling performance — optimum compliance resistance keeps the suspension geometry predictable and responsive
• Alignment retention — helps maintain accurate caster and camber settings after alignment service
• Chemical and element resistance — polyurethane resists oils, road chemicals, and weathering that degrade conventional rubber bushings
• Application-specific design — engineered to exact specifications for a direct-fit replacement on GM front lower control arms
• Made in the USA — manufactured to Prothane's performance and durability standards

Note: As with all polyurethane suspension components, a slight increase in NVH (noise, vibration, and harshness) compared to OEM rubber is normal and expected. Most performance-oriented drivers consider this an acceptable trade-off for the improved handling and longevity that polyurethane provides.
