Why KC Racing Spurs Outperform the Competition

•  Wider Tooth Face for Superior Strength & Durability: At 2mm wide, our gears provide significantly more contact area and load-bearing capability than narrower options like others 1.3mm face. This translates to better power handling, reduced tooth stress under extreme torque, and longer life during high-RPM launches and hard runs.

•  Ultra-Lightweight 7076-T6 Alloy: This premium aerospace-grade material offers exceptional strength-to-weight ratio with low rotational inertia. You get lightning-quick acceleration and higher top-end speeds without sacrificing reliability—perfect for competitive drag setups.

•  Hard Anodized Surface: The thick, wear-resistant oxide layer dramatically boosts surface hardness (400–600+ HV) and abrasion resistance far beyond bare machined aluminum. Teeth stand up to aggressive meshing with steel or hard pinions, resist galling/scoring, and maintain precise engagement run after run. Enhanced corrosion protection keeps them looking and performing like new.

The result? Faster ETs, higher trap speeds, and gears that survive session after session—while competitors with narrower, untreated designs wear faster and lose efficiency.
