DMS Full Billet LSA Supercharger Tensioner Bracket

Replaces GM PN# 12606500

If you’re experiencing belt deflection or shredding on your high-horsepower LSA build, it’s time to upgrade from the weak OEM cast tensioner bracket to the DMS Full Billet LSA Tensioner Bracket. Precision-machined from high-grade billet aluminum, this bracket is a direct replacement for the now-discontinued GM PN# 12606500.

Designed to handle the demands of large superchargers such as the Kong, Magnuson, or Harrop 2650, this bracket eliminates the flex and deflection that plagues the factory cast version—especially in 10, 11, or 12 rib belt setups. Whether you’re building a boosted LSA swap or replacing a worn factory part, this bracket offers superior strength and reliability.

Key Features:

• Full billet construction for maximum rigidity and zero deflection

• Direct replacement for discontinued OEM part #12606500

• Ideal for high-output setups using Kong, Magnuson, or Harrop 2650 superchargers

• Supports 10, 11, and 12 rib belt systems

• Perfect for LSA conversions or OEM replacements

• Optional bolt kit available with all necessary fasteners for installation

Stop worrying about belt alignment and focus on putting the power down. The DMS Billet LSA Tensioner Bracket is built to outlast and outperform the stock bracket in even the most extreme setups.
