Rear Upper Control Arm Bushing for Tesla Model S/X (2012-2023) | 1021420-00-ACT

Why This Bushing Matters for Your Model S/X

What It Actually Does (No Tech Jargon)

• Shock Absorption: Made from high-grade rubber, it cushions the metal-on-metal contact between the control arm and chassis. When you hit a curb or rough patch, it soaks up the impact so you don’t feel every bump.
• Vibration Dampening: Blocks road noise and vibrations from reaching the cabin. A failing bushing lets these vibrations pass through, turning your quiet Tesla ride into a noisy, rattling experience.
• Alignment Keeper: Holds the rear control arm in precise position, ensuring your wheels stay properly aligned. No more “drifting” on straight roads or uneven tire tread wear (which costs you in premature replacements).
• Flex with Purpose: Flexes just enough to let the control arm move during turns or suspension compression, but stays rigid enough to maintain stability. It’s the balance between flexibility and control.

Signs Yours Needs Replacement

• Clunking/creaking noises: A “knock” or “squeak” from the rear when turning, braking, or going over bumps. This is the sound of worn rubber letting metal parts grind together.
• Loose handling: Your Model S/X feels “wobbly” on the highway, or takes longer to steady after a turn. The bushing can’t keep the control arm stable anymore.
• Uneven tire wear: Bald spots on the inner or outer edges of your rear tires. Misalignment from a bad bushing forces tires to drag at an angle.
• Vibration in the cabin: Rattling or buzzing felt through the seats or steering wheel, even on smooth roads. The bushing isn’t blocking road vibrations like it should.

Built to Outlast the Road

Why It’s Better Than Aftermarket Junk

• Tesla-Calibrated Rubber: The EPDM compound is engineered to handle the weight of Model S/X (up to 5,500 lbs). It won’t compress or crack under heavy loads, unlike generic bushings.
• Steel Core Reinforcement: A rigid steel inner sleeve prevents the bushing from deforming under stress, keeping your control arm aligned for longer.
• Weatherproof: Resists oil, road salt, and UV damage—critical for rear suspension parts exposed to slush, rain, and debris.
• Drop-In Fit: Exact dimensions match your original bushing, so installation requires no trimming or modification.
