Whiteline Rear Lower Rearward Control Arm – 2017-2026 Tesla Model 3

Sharpen the rear suspension geometry of your Tesla Model 3 with the Whiteline Rear Lower Rearward Control Arm — a complete, ready-to-install replacement arm pre-fitted with Whiteline’s market-leading synthetic elastomer bushings. The rear lower rearward control arm is a critical component in the Model 3’s multi-link rear suspension, directly influencing toe geometry, rear end stability, and handling balance under load. Whiteline’s pre-fitted bushing design means no pressing, no fabrication, and no damaged arms — just bolt it on, align, and drive.

Key Features:

• Complete ready-to-install arm — Whiteline synthetic elastomer bushings pre-fitted at the factory; no pressing or bushing installation required
• Whiteline synthetic elastomer bushings — market-leading bushing material engineered for improved handling precision and long-term durability
• Rear lower rearward position — directly influences rear toe geometry and rear end stability under acceleration and cornering loads
• Direct replacement — engineered for the 2017–2026 Tesla Model 3 rear suspension using factory mounting points
• Eliminates bushing press work — no specialist tools required, no risk of damaged arms or housings
• Whiteline engineering — over 40 years of suspension component development for performance and motorsport applications

Performance Benefits:

• Improved Rear Toe Stability: The rear lower rearward control arm is a primary toe-influencing link in the Model 3’s multi-link rear suspension — firmer Whiteline bushings reduce the toe deflection that causes rear end instability under hard cornering and acceleration
• Enhanced Rear End Stability: Reduced bushing compliance keeps the rear wheels more precisely positioned under lateral and longitudinal loads, improving straight-line stability and cornering confidence
• Consistent Rear Geometry: Whiteline’s synthetic elastomer maintains rear suspension geometry more accurately under load than factory rubber bushings — critical for a rear-heavy EV platform where rear suspension compliance directly affects handling balance
• No Press Required: Complete arm with pre-fitted bushings eliminates the most time-consuming and risk-prone part of a bushing upgrade
• Long-Term Durability: Whiteline’s synthetic elastomer resists oil, ozone, and UV degradation far better than factory rubber, maintaining performance characteristics over a significantly longer service life

What’s Included:

• Whiteline rear lower rearward control arm with pre-fitted synthetic elastomer bushings (WA534)
• Installation hardware
• Installation instructions

Installation Notes:

• Professional installation strongly recommended
• Full alignment required after installation — rear toe adjustment is critical after replacing this arm
• No bushing pressing required — bushings are pre-fitted at the factory
• Torque all fasteners to Whiteline’s specified values with the suspension at ride height (not full droop)
• Allow suspension to settle before final alignment check
• Re-torque all fasteners after first 500 km

Complete Arm vs. Bushing Replacement:

Replacing individual bushings in an existing control arm requires removing the arm, pressing out the old bushings, pressing in the new ones, and reinstalling — a process that demands specialist press tools, risks damaging the arm housing, and is time-consuming even for experienced technicians. Whiteline’s complete arm approach eliminates all of this: the arm arrives with Whiteline’s synthetic elastomer bushings already installed, ready to bolt directly onto the vehicle. The result is a faster, cleaner installation with no risk of bushing installation errors or damaged components — and the same performance improvement as a bushing-only upgrade.

Rear Lower Rearward Control Arm – Why It Matters:

In a multi-link rear suspension like the Tesla Model 3’s, each control arm link controls a specific aspect of wheel position and geometry. The rear lower rearward arm is one of the primary toe-controlling links — it resists the rearward and lateral forces that act on the rear wheel during cornering and acceleration. When the bushings in this arm degrade or deflect under load, the rear wheel can toe out momentarily, causing the rear end to feel loose, unstable, or unpredictable under hard driving. Whiteline’s firmer synthetic elastomer bushings reduce this deflection, keeping the rear wheel in its intended position and delivering a more stable, predictable rear end — particularly important on the Model 3’s rear-heavy platform.

Whiteline Synthetic Elastomer:

Whiteline’s synthetic elastomer bushing material is the result of over 40 years of suspension component development. It’s engineered to be firmer than factory rubber — reducing the compliance that allows suspension geometry to shift under load — while remaining compliant enough for street use without the harshness of solid mounts. The material resists oil, ozone, and UV degradation, maintaining its performance characteristics over a much longer service life than factory rubber.

Why Whiteline?

Whiteline has been engineering suspension components for performance and motorsport applications since 1979. Their product lineup — sway bars, control arms, bushings, and alignment components — is trusted by professional racing teams and enthusiast drivers worldwide. Whiteline’s expansion into EV platforms like the Tesla Model 3 reflects the growing performance enthusiast community around electric vehicles and Whiteline’s commitment to providing suspension solutions for the platforms that matter to drivers.

Perfect For:

• 2017–2026 Tesla Model 3 owners seeking improved rear suspension geometry and stability
• Model 3 Performance builds wanting reduced rear toe deflection under hard cornering and acceleration
• Track day and autocross Model 3 builds requiring more precise rear suspension control
• High-mileage Model 3s where factory rubber bushing degradation is contributing to rear end vagueness
• Anyone pairing with the Whiteline front upper control arm (WA533) for a complete front and rear suspension geometry upgrade

Pro Tip: Pair with the Whiteline front upper control arm (WA533) for a complete Model 3 suspension geometry upgrade. Addressing both front and rear bushing compliance simultaneously delivers the most balanced and consistent improvement in handling precision.

Note: Full alignment with rear toe adjustment is required after installation. Do not drive the vehicle without a proper alignment after replacing this arm — incorrect rear toe will cause uneven tyre wear and unpredictable handling.
