Part No. TT193 | Fits GM Gen III / Gen IV LS Engines | Sold Each
Direct-fit timing chain guide for GM LS series V8 engines. The guide keeps the timing chain under control on the slack side, reducing chain whip and slap that lead to noise, accelerated chain stretch, and wear on the timing cover and sprockets. An inexpensive part that is worth replacing any time the front cover is off — especially during a timing set, cam swap, or full rebuild.
Manufactured to OE specification for correct fit and function. Enginetech supplies engine components to rebuilders and professional shops nationwide.
