Body & Radiator Bushing Silverado 1500 99-14

The Body & Radiator Bushing Silverado 1500 99-14 from Whiteline Performance is a complete polyurethane bushing kit engineered to eliminate excessive body movement and improve chassis rigidity on full-size GM trucks. As a mechanic who has rebuilt countless suspension systems, I can tell you that worn factory rubber bushings allow dangerous deflection under acceleration, braking, and cornering—compromising handling and accelerating wear on driveline components. This kit replaces those compromised bushings with precision-molded polyurethane versions that maintain geometry and dampen vibration far longer than OEM rubber.

Polyurethane bushings resist oil degradation, UV exposure, and ozone cracking that destroy factory rubber within 100,000 miles on modified or towing trucks. The Body & Radiator Bushing Silverado 1500 99-14 kit includes both body mount bushings and radiator support bushings—two critical mounting points that often get overlooked during basic maintenance. The black polyurethane material is formulated to provide consistent compliance across temperature extremes while maintaining lateral stiffness; this reduces frame flex during load transfer and keeps suspension geometry stable during acceleration or emergency maneuvers. Installation is straightforward on the 1999–2014 Silverado 1500 platform, requiring only basic hand tools and a jack.

This kit is ideal for owners who tow regularly, drive lifted trucks, or simply want to restore chassis stiffness on high-mileage examples. Towing trucks especially benefit from the Body & Radiator Bushing Silverado 1500 99-14 because worn radiator support bushings allow the core to shift under load, stressing hose connections and radiator tanks. Whether you're running a stock truck or one with suspension modifications, upgrading to polyurethane throughout the body mount system will noticeably improve pedal response, steering feel, and overall structural integrity. Compatibility is confirmed for all full-size Silverado 1500 models from 1999 through 2014.
