Product Details

Features

  • Polished aluminum tensioner for TSP LS serpentine front drive accessory kits
  • Replacement or supplemental tensioner — not for stock LS accessory drives
  • Fits GM LS Gen. III/IV small block (4.8L–6.2L) accessory drive applications
  • Confirm belt style, groove count, and pulley spacing before ordering

Description

This polished aluminum belt tensioner is designed as a replacement or supplemental component for TSP's LS serpentine front drive accessory kits. It's built to match TSP's existing kit hardware for proper belt tracking and accessory alignment — it is not a multi-pulley kit itself, and it's not intended as a direct factory replacement for stock LS accessory drive systems.

The polished finish gives a clean, show-quality appearance in the engine bay, matching other polished components in a dressed-up LS accessory drive. Confirm belt style, groove count, and pulley spacing against your specific TSP kit before ordering, since tensioner geometry must match the rest of your front drive setup exactly.


Applications
Fits GM LS Gen. III/IV small block engines (4.8L–6.2L) used in Camaro, Corvette, Silverado/Sierra, Tahoe/Suburban/Yukon, GTO, G8, and LS engine swap applications — specifically for use with TSP's LS serpentine front drive accessory kits.

Installation
Verify compatibility with your specific TSP kit before ordering. Match belt style, groove count, and pulley spacing to your existing front drive kit. Confirm belt alignment, pulley offset, and mounting style before final installation. Not intended as a direct factory replacement tensioner for stock LS accessory drive systems.
