COMP Cams Hi-Tech Gear Drive System Standard GM Blocks (3 Bolt Cams and 24x/58x LS Engines)

These gear drive timing sets are specifically designed for LS engines used in racing, street, marine and extreme applications. They provide the most accurate valve timing possible by eliminating chain flutter and backlash. They bolt on without modification, maintaining the stock oil pump and timing cover for all LS-based engines except dry sump models. Designed for three-bolt cams and work with all 24x and 58x LS engines. Based on the award-winning COMP Cams LS Sprint Car Gear Drive, these are the world’s only gear drives for LS engines.
Requiring no modifications, our gear drive set for LS engines maintains the most accurate valve timing by eliminating chain flutter and backlash. This kit is compatible with all wet-sump 24x/58x LS engines with a 3-bolt camshaft.
See 5494 for applications with raised cam locations such as the RHS LS Race Block. 3-Bolt Camshaft Configuration only. Requires the use of "54-" 3-Bolt camshafts. Dry sump LS engines require an external oil pump.
