Katech KAT-A4425 Tensioner Assembly - Proven Race Performance for Your LS Engine

Since 1997, Katech Engineering LLC has been a key player in the C5-R racing program, developing high-performance solutions for Corvette racing vehicles. One of the first products to arise from this successful partnership is the KAT-A4425 Tensioner Assembly.

Racing conditions often caused belts to slip off, leading to critical issues such as a loss of power steering, charging, and cooling. Designed to solve this, the KAT-A4425 brings race-proven reliability to street vehicles by preventing belt misalignment and maintaining optimal belt tension.

This assembly has proven itself not only on the track but in LS-powered V8 engines worldwide. Whether you're on the race track or the road, the KAT-A4425 is the ultimate solution for eliminating belt-throwing issues.

Key Features:

• Machined from USA 6061 T6 Aluminum: Precision-engineered for maximum strength and durability.
• Anodized Tensioner with Laser-Etched Logo: A durable finish that offers corrosion resistance and a clean, professional look.
• FEA-Analyzed Design: Weight-optimized and rigidity-enhanced through advanced analysis, ensuring long-lasting performance.
• OEM Tensioner Pulley with Raised Belt Guides: Keeps the belt centered and prevents it from walking off the pulley.
• Complete Installation Hardware: Comes with all necessary hardware for most applications (Note: F-body and GTO applications require KAT-4428, sold separately).
• Quick Installation: Less than 15 minutes to install, making it easy to upgrade your LS engine.
• Race-Proven: The original aftermarket tensioner approved for use in most sanctioned racing series involving LS engines.

This product not only helps prevent dangerous belt-related failures but also ensures the durability and reliability that both professional racers and enthusiasts demand.
