When it comes to building a capable, reliable, and trail-ready Toyota Tundra, your suspension components play a huge role in performance. The tundra control arm is one of those upgrades that doesn’t always get the spotlight, but it should. Westcott Designs™ engineered their billet rear upper trailing arms for the 2023–2025 Tundra to handle the toughest conditions, improve suspension geometry, and deliver unmatched durability.
Whether you’re towing, overlanding, or pushing your Tundra hard on technical trails, upgrading your control arms will give you a more stable, responsive, and long-lasting setup. Here’s why it matters — and why Westcott Designs™ is leading the charge.
Why Upgrade Your Tundra Control Arm?
The factory control arms on the 3rd Gen Tundra are functional, but they’re not built for extreme use. Over time, they can flex, wear, and compromise alignment — especially if you’re running larger tires, hauling heavy loads, or frequently flexing your suspension off-road.
Key reasons to consider an upgrade:
-
Strength & Durability – Billet aluminum construction far exceeds OEM steel in resistance to bending and fatigue.
-
Improved Geometry – Corrects suspension angles for better articulation and reduced bushing stress.
-
Long-Term Reliability – Higher-quality bushings and hardware reduce maintenance and downtime.
-
Better Performance – A solid rear end translates into improved traction, handling, and ride quality.
Upgrading your Tundra control arm isn’t just about surviving the trail — it’s about enjoying a smoother, more predictable drive everywhere you go.
Billet vs. Stock: What’s the Difference?
Westcott Designs™ builds their billet rear upper trailing arms from CNC-machined 6061-T6 aluminum, a premium material known for its exceptional strength-to-weight ratio. The result? Arms that resist flex and deformation under heavy loads while shedding unnecessary weight.
Stock Control Arms:
-
Stamped steel construction
-
Factory bushings prone to wear
-
Adequate for highway use but limited off-road
Westcott Designs™ Billet Arms:
-
CNC-machined from solid billet aluminum
-
Upgraded, serviceable bushings
-
Precision tolerances for perfect fitment
-
Black anodized finish for corrosion resistance
-
Proudly made in the USA
The difference is immediately noticeable — both in performance and in build quality.
Installation and Performance Gains
The Westcott Designs™ billet rear upper trailing arms are a direct bolt-on replacement for the factory arms, meaning no cutting, welding, or major modifications. Once installed, you’ll notice:
-
Reduced axle wrap under acceleration
-
Better tracking during towing or hauling
-
Improved suspension travel without binding
-
More stable handling over uneven terrain
Because they’re designed specifically for the 2023–2025 Toyota Tundra, installation is straightforward and compatible with stock or aftermarket suspension systems.
