Rear Suspension Knuckle - Right for Tesla Model Y | 1188416-00-F

The Right Rear’s Hidden Architect of Model Y’s Ride Quality

How It Shapes Your Model Y’s Personality

• Urban Toughness: Navigating city streets means constant hits from curbs and potholes. This knuckle absorbs those impacts, distributing force across the rear suspension to prevent that “jarring” feel in the cabin—keeping your ride smooth even on rough asphalt.
• Payload Poise: Whether you’re hauling groceries, luggage, or outdoor gear, it supports up to 1,600 lbs of dynamic load on the right rear, ensuring the wheel stays aligned and the tire wears evenly (no more premature replacements).
• Cornering Confidence: When you lean into a right turn, the knuckle resists lateral forces, keeping the tire planted firmly on the road. It’s why your Model Y feels stable, even when you need to swerve suddenly.

Signs Your Right Rear Knuckle Needs a Refresh

• Right Rear Tire Tells a Story: The right rear tire’s inner or outer edge is worn down faster than the left? That’s the knuckle warping, throwing off camber alignment and wasting your tire investment.
• Rear End Shimmies: At speeds above 55 mph, you feel a vibration in the back. A bent knuckle is making the wheel spin unevenly, risking damage to the hub bearing (a $250+ fix) if left unchecked.
• Clunks Over Bumps: A metallic “knock” from the right rear when hitting speed bumps? Loose mounting points on the knuckle are to blame, and they’ll only get worse—potentially damaging $300+ suspension links.

Why It Outlasts Aftermarket Alternatives

• Forged for Durability: Made from high-strength SAE 1045 steel, forged (not cast) to create a dense, fatigue-resistant structure. It handles years of road abuse without bending or cracking.
• Precision Fit: CNC-machined to within 0.02mm of Tesla’s specs, so it bolts perfectly to the right rear control arms, brake caliper, and hub. No grinding, no forcing—just a seamless install.
• Weatherproof Design: A multi-layer coating (zinc + epoxy) resists rust and corrosion, even in salty winter climates or coastal humidity. No seized bolts, no premature failure.
