Bushing Orange 3.375OD/ .750ID 55 DR

The Bushing Orange 3.375OD/.750ID 55 DR from ALLSTAR PERFORMANCE is a precision suspension and drivetrain bushing engineered for high-performance automotive applications. This polyurethane bushing serves as a critical vibration-damping component in chassis systems, engine mounts, and control arm assemblies where factory rubber bushings degrade under load. Built for drag racers, street performance enthusiasts, and serious mechanics, this bushing delivers the compliance and durability needed in competition-grade vehicles while maintaining superior articulation over extended operating cycles.

With a 3.375-inch outer diameter and 0.750-inch inner diameter, this 55-durometer bushing offers the ideal hardness balance for performance applications—firm enough to eliminate deflection under cornering and acceleration loads, yet compliant enough to absorb drivetrain shock and suspension harmonics. The 55 DR (durometer rating) specification positions this bushing between soft street-duty compounds and track-only rigid elastomers, making it suitable for both daily-driven builds and weekend competition vehicles. Polyurethane construction resists heat, oil, and UV degradation far better than OEM rubber, extending service life and maintaining consistent handling characteristics over thousands of miles.

Mechanics and fabricators typically specify this bushing for engine mount kits, transmission crossmember assemblies, and independent suspension rebuilds where precision tolerances and load ratings matter. Installation requires standard pressing tools or a hydraulic press to seat the bushing into chassis or control arm bores—ensure bore dimensions match the 3.375-inch OD specification before ordering. Weighing just 0.85 pounds, this compact bushing integrates seamlessly into OEM and custom mounting points across domestic and import platforms. Whether you're restoring a vintage race car, upgrading a street machine, or engineering a complete suspension overhaul, the ALLSTAR PERFORMANCE Orange bushing delivers repeatable performance without the squeaking, cracking, or compliance issues associated with aged rubber components.
