Bushing Insert for ALL56248 40DR Soft

The Bushing Insert for ALL56248 40DR Soft is a polyurethane trailing arm bushing designed for drag racing and high-performance automotive applications where suspension compliance and vibration isolation are critical. This soft-durometer insert serves racers and suspension builders who need predictable bushing performance under extreme loads while maintaining drivability during acceleration and cornering events. The 40-durometer rating provides the elasticity necessary to absorb driveline shock and reduce harshness transmitted to the chassis during launch.

Manufactured from black polyurethane material, this trailing arm bushing insert delivers consistent deflection characteristics across repeated loading cycles—essential for maintaining consistent launch behavior and predictable handling. The softer 40-durometer compound absorbs impact energy more effectively than stiffer alternatives, reducing the transfer of suspension oscillation to the frame and driver feedback. At 0.15 lbs and compact dimensions of 4 x 1.75 x 7 inches, the insert integrates seamlessly into existing trailing arm assemblies while maintaining factory geometry and alignment requirements. This formulation resists degradation from heat cycling and fuel exposure common in drag racing environments.

Drag racers, street performance enthusiasts, and chassis builders benefit most from this replacement bushing, particularly those running vehicles with independent rear suspension systems or ladder bars requiring compliance. Installation is straightforward—the insert drops into the existing ALL56248 trailing arm bushing housing without requiring frame modification. For optimal results, pair this soft-durometer insert with properly tuned suspension geometry and consider combining it with complementary bushing upgrades throughout the suspension to achieve balanced compliance and control.
