Katech LS Serpentine Manual Billet Belt Tensioner

Katech LS Manual Billet Serpentine Belt Tensioner

Championship-Proven Belt Stability for High-Performance LS Engines

The Katech LS Billet Serpentine Belt Tensioner is a precision-engineered upgrade designed to help minimize belt slip and improve accessory drive stability under the most demanding conditions. Crafted from USA 6061-T6 billet aluminum and optimized through Finite Element Analysis (FEA), this tensioner delivers superior rigidity and consistent belt tension where factory tensioners can flex under high-RPM and high-load conditions.

Developed from Katech's legendary C5-R Corvette racing program, this component carries decades of motorsports innovation into your LS-powered street or track build. Every detail reflects race-proven engineering, from its CNC-machined billet construction to its corrosion-resistant anodized finish.

Factory tensioners can flex under extreme operating conditions, allowing the belt to walk off-center or even be thrown from the pulley. Katech solved this problem for endurance racing, and that same engineering is now available for your performance build. An OEM-style pulley with raised belt keepers helps maintain proper belt alignment and reduces the likelihood of belt walk for maximum reliability.
