Why It Matters for Your Tesla
Precision Handling: The rubber-metal composite design minimizes unwanted movement between the knuckle and suspension, maintaining accurate wheel alignment. This reduces tire scrubbing, improves cornering stability, and ensures straight-line tracking—critical for Tesla’s high-performance capabilities.
Vibration & Noise Reduction: The high-density rubber core absorbs road vibrations and dampens noise from uneven surfaces, preventing harsh feedback from reaching the cabin. This preserves the Model S/X’s signature quiet, smooth ride.
Durable Construction: The steel core provides structural rigidity to withstand suspension loads, while the rubber resists wear, oil, and ozone degradation. Unlike generic bushings, it’s engineered to match Tesla’s suspension stress thresholds, lasting 80,000+ miles under normal use.
OEM-Grade Fit: Machined to exact tolerances, it replaces the original bushing without modifications. Perfect alignment with knuckle and suspension mounting points ensures proper preload and function, avoiding premature failure.
Installation Notes
Professional Installation Recommended: Requires a hydraulic press to remove old bushings and press in the new ones. Incorrect installation can cause misalignment or bushing damage.
Replacement Indicator: Replace if you notice clunking noises from the rear, uneven tire wear, or loose handling—signs of worn bushings.
Service Pairing: For best results, replace all 4 rear knuckle bushings simultaneously to maintain balanced suspension performance.
