Lower Bushing Round 1.65

The Lower Bushing Round 1.65 by Kluhsman Racing Products is a precision control arm bushing engineered for drivers who demand responsive steering geometry and reduced NVH (noise, vibration, harshness) in street and light track applications. This bushing addresses worn OEM components that create vague steering feel, suspension clunk, and accelerated wear on tie rods and wheel bearings. Whether you're refreshing a daily driver or dialing in a weekend warrior, a quality lower bushing replacement is foundational to chassis stiffness.

The 1.65-inch round profile design maintains OEM compliance and load characteristics while offering superior durometer and elastomer compound compared to aged rubber. This geometry preserves the vehicle's designed roll center and bump steer curve—critical when factory bushings harden or crack after years of thermal cycling and road salt exposure. The compact footprint (2.85 × 1.95 × 3.55 inches) and 0.99-pound weight ensure straightforward installation without frame modifications, and the material resists degradation from UV, ozone, and temperature extremes better than degraded OEM rubber.

Suspension builders and DIY enthusiasts benefit most from this bushing when replacing worn lower control arm assemblies or performing a full front-end refresh. Installation requires standard hand tools and a hydraulic press or bushing tool; many shops can turn the job in under two hours per side. Confirm fitment against your specific control arm assembly, as bushing bore diameter and mounting tabs vary by manufacturer and model year.
