Speed 77-Inch Wide Billet Upper Control Arms

Speed UTV is proud to announce the release of our all-new 77-inch wide 7075 billet aluminum upper control arms, engineered as a direct replacement upgrade for any Speed UTV equipped with a 77-inch wide suspension platform.

Why Upgrade from Chromoly to Billet Aluminum?

7075 billet aluminum, deliver a component that is not only stronger but also far more resistant to fatigue, keeping suspension geometry consistent even under the most extreme conditions. This means more predictable handling, tighter steering response, and longer service life.

Pinch-Bolt vs. Jam-Nut Design: Built for Reliability

We’ve re-engineered the arm ends to feature a pinch-bolt design instead of the traditional jam-nut style. The result is a connection that is less prone to loosening, offers superior clamping force, and ensures maximum reliability in competition or aggressive trail use. 

Why Billet Aluminum is Becoming the Standard

Across motorsports, from UTVs to trophy trucks to performance side-by-sides, billet aluminum suspension components are becoming the gold standard. The reason is simple: billet machining allows for precise engineering tolerances, optimized strength-to-weight ratios, and unmatched durability compared to tubular designs. The result is a part that not only looks race-inspired but performs at the highest level.

7075 vs. 6061 Aluminum – Why It Matters

Not all aluminum is created equal. While 6061 aluminum is widely used, it simply cannot match the strength of 7075 in high-stress applications.

• 7075 aluminum offers nearly double the tensile strength of 6061, making it far more resistant to bending, stretching, or cracking.

• This makes 7075 the ideal choice for suspension arms, where loads are extreme, and failure is not an option.

When you’re pushing your Speed UTV at race pace—or simply demanding maximum reliability from your machine—7075 billet arms are the only choice.

Direct Replacement Fit

These billet upper control arms are designed as a bolt-on, direct replacement for all upper control arms on 77-inch wide Speed UTVs. No modification required—just increased strength, durability, and performance the moment you install them.
