Body Mount Bushing Chevy/GMC C/K-Series

The Body Mount Bushing for Chevy and GMC C/K-Series trucks represents a critical wear item for owners of full-size trucks from the 1988–1998 generation. Original rubber bushings deteriorate under the constant flexing and loads imposed by suspension articulation, engine torque, and road impacts—resulting in clunking noises, increased body movement, and accelerated wear on adjacent components. Whiteline Performance's polyurethane replacement addresses this problem with a material engineered to outlast OEM rubber by a significant margin while restoring the structural rigidity that new trucks possess.

Whiteline's polyurethane formulation offers superior durability and resistance to UV degradation, ozone cracking, and the thermal cycling that degrades factory rubber in weeks. The black polyurethane material bonds to zinc-plated steel sleeves, creating a composite bushing that maintains its elasticity across temperature extremes while resisting the fluid absorption that causes swelling and premature failure in rubber. The extended-cab fitment ensures proper clearance and load distribution across the truck's body mounting points, critical for preventing frame flex and maintaining alignment integrity under towing or heavy-load scenarios. This kit includes all necessary bushings for a complete body mount renewal on applicable Chevy and GMC trucks.

Mechanics and serious truck owners tackling frame-off restorations, suspension rebuilds, or addressing persistent creaks and movement will find this bushing set essential for modern drivability. Installation requires basic hand tools and mechanical familiarity—the zinc-plated sleeves press into frame and body mounting locations where original rubber has deteriorated. Extended-cab C/K-Series trucks (1988–1998) benefit most from this upgrade, as larger cabs and extended wheelbases experience greater torsional loads than their short-bed counterparts. Whether you're solving a chronic rattling condition or performing preventive maintenance as part of a comprehensive truck refresh, Whiteline's polyurethane construction delivers the longevity and structural response that modern driving demands.
