Rear Suspension Knuckle - Right for Tesla Model X (2015-2021) | 1027416-00-D
The Right Rear’s Unsung Guardian of Stability
In the Tesla Model X’s rear suspension system, the right knuckle is the quiet workhorse that turns chaos into control. Whether you’re navigating a rain-slicked highway with a full load, backing up a steep driveway with falcon-wing doors open, or towing a boat through a curve, the 1027416-00-D ensures the right rear wheel stays planted, aligned, and responsive. Unlike generic parts that treat all SUVs the same, this knuckle is engineered specifically for 2015-2021 Model X—accounting for its 67.7-inch rear track, battery-heavy rear weight bias, and the unique stresses of its dual-motor setup.
How It Elevates Your Model X’s Capabilities
The Model X thrives on versatility, and this right rear knuckle is built to match:
Load Handling Expertise: When you’ve got luggage, groceries, and passengers filling the cabin, it supports up to 1,800 lbs of static weight without bending—keeping the right rear tire evenly pressed to the road for consistent traction.
Towing Stability: Hauling a trailer? It counteracts the lateral forces that would make the rear end sway, working with the suspension links to keep the SUV tracking straight even when the load shifts.
Rough Road Resilience: Potholes, broken pavement, or off-road ruts—this knuckle absorbs impacts and distributes them across the rear suspension, turning jarring bumps into smooth transitions that keep passengers comfortable.
Clues Your Right Rear Knuckle Needs Attention
Your Model X sends clear signals when the right rear knuckle is failing—heed them to avoid bigger issues:
Right Rear Tire Misery: The right rear tire’s shoulder is worn ragged, while the left looks fine. This uneven wear is a red flag: the knuckle is warped, throwing off camber and toe alignment.
Rear Vibration at Speed: Above 60 mph, you feel a rhythmic shake in the rear. A bent knuckle is making the wheel spin out of true, risking damage to the hub bearing (a $300+ replacement) if left unaddressed.
Braking Thuds: A dull “clunk” from the right rear when you brake hard? It’s likely loose mounting points on the knuckle—ignoring it could let the wheel shift under stress, compromising stopping power.
Why It Outperforms Aftermarket Knockoffs
Aftermarket knuckles use thin, cast metal that cracks under the Model X’s weight. This one? It’s built like Tesla intended:
Forged Strength: Made from SAE 1045 high-carbon steel, forged (not cast) to create a dense, uniform structure that resists bending. It’s why it handles years of potholes and heavy loads without fatigue.
Precision Engineering: CNC-machined to within ±0.02mm of Tesla’s specs, so it fits perfectly with the right rear control arms, brake caliper, and hub. No “adjustments” needed—just bolt it on and go.
Corrosion Resistance: A 5-layer coating (zinc phosphate + epoxy primer + topcoat) stands up to 1,000 hours of salt spray. Whether you’re in coastal humidity or snowy, salted roads, it won’t rust or seize.
What You Get (and Why It’s Worth It)
The Knuckle: 1027416-00-D, ready to install with no missing pieces.
3-Year Warranty: Covers structural defects—we’re confident it will outlast the miles.
Model X-Specific Guide: Includes torque specs (120 Nm for control arms, 150 Nm for trailing arm) to ensure your mechanic gets the installation right the first time.
Don’t Risk Your SUV’s Performance
A cheap aftermarket knuckle might save a few dollars upfront, but it’ll cost you in uneven tires, alignment fixes, and even safety risks. This knuckle is built to Tesla’s standards, so your Model X’s right rear stays stable, whether you’re running errands or embarking on a road trip.
Click “Add to Cart” to restore your rear suspension’s confidence. Ships in 48 hours with tracking.
Pro Tip: Pair with a rear hub bearing (1043284-00-A) for a complete right rear refresh—your SUV will drive like new.
