Rear Stabilizer Anti-Roll Sway Bar Link for 2017+ Tesla Model 3 / 2020+ Model Y | 1044485-00-A (CFN Brand)

1. Roll Suppression & Handling Enhancement: Transmits torque between the rear stabilizer bar and suspension components; when the vehicle turns or encounters uneven roads, it helps the stabilizer bar exert anti-roll force, reducing body lean (oversteer/understeer) and improving driving stability—critical for maintaining control during high-speed cornering or emergency maneuvers.
2. Suspension Vibration Damping: Features a built-in precision ball joint (with high-temperature grease filling) that absorbs micro-vibrations from the road, reducing the transfer of suspension noise and jolts to the cabin—preserving the Model 3/Y’s signature smooth ride quality.
3. Suspension Geometry Maintenance: Maintains the rear suspension’s factory-calibrated alignment parameters; unlike worn links that cause loose connections, it keeps the stabilizer bar in the correct position, avoiding abnormal tire wear (e.g., uneven tread wear on rear tires) and ensuring consistent braking and steering response.

• Rod Body: Made of 45# carbon steel (heat-treated, tensile strength ≥600MPa) with a black electrophoretic coating—resisting rust and corrosion from road salt, rain, or mud (passes 720-hour ASTM B117 salt spray tests).
• Ball Joint: The ball stud is made of chrome-plated bearing steel (hardness ≥HRC 58) for wear resistance; the dust boot uses high-temperature-resistant TPE (Thermoplastic Elastomer) material, which withstands -40°C to 120°C temperature fluctuations (no cracking in cold winters or softening in hot summers) and prevents dust/water from entering the ball joint.
• Mounting Hardware: Includes OEM-specification nuts and washers (zinc-plated for corrosion resistance), ensuring a tight fit with the suspension components and avoiding loosening from long-term road vibration.

1. Lift the vehicle’s rear end and secure it with jack stands (ensure stable support); remove the rear wheel corresponding to the link to be replaced (left/right side—note: this part is for a single side; confirm LH/RH fitment before installation).
2. Locate the old sway bar link: it connects the rear stabilizer bar (upper end) to the rear strut (lower end). Use a 13mm socket to remove the upper nut (securing to the stabilizer bar) and a 15mm socket to remove the lower nut (securing to the strut/knuckle); if the ball joint is seized, gently tap the link with a rubber mallet to loosen it (avoid damaging adjacent suspension parts).
3. Remove the old link and clean the mounting surfaces (stabilizer bar bracket, strut mounting point) with a wire brush—wipe away rust, debris, or old grease to ensure a tight fit for the new link.
4. Align the CFN sway bar link with the mounting points: first attach the upper end to the stabilizer bar, then connect the lower end to the strut/knuckle; hand-tighten the nuts first to avoid cross-threading.
5. Use a torque wrench to tighten the nuts to Tesla’s official specs: upper nut (28±2 Nm), lower nut (35±3 Nm)—over-tightening may damage the ball joint, while under-tightening can cause loose connections and noise.
6. Reinstall the rear wheel, lower the vehicle, and perform a short road test: check for abnormal noises (e.g., “clunking” when turning) and confirm stable handling—if needed, have a professional align the rear suspension to ensure geometry accuracy.
