These Holley Transmission Installation Kits come complete with everything you need to bolt a TKX or TKO transmission to almost any Gen III, Gen IV, and Gen V Small Block Chevrolet Engines with a 6-bolt or 8-bolt flywheel. Built with a mixture of our best brands including Lakewood and Hays, this kit includes a bellhousing, billet steel flywheel, clutch and pressure plate, hydraulic release bearing, roller pilot bearing, and all hardware needed to install these components. The 319-504 is set up to be used with the 6-bolt flywheel LS engines which are the majority of the Gen III and Gen IV engines produced before 2009 (LS1, LS2, LS3, LS6, LS7, LM7, LQ9, L33, and similar truck engines). The 319-505 is very similar to the 319-504 but is designed to be used with the 8-bolt flywheel LS and Gen V LT engines that come after 2009 (LSA, LT1, LT4, L83, and similar truck engines).

Features:

Designed for Gen III/Gen IV Small Block Chevrolet Engines with 6-bolt crank/flywheel using a TKX or TKO transmission
Light weight cast aluminum bellhousing and stamped steel dust cover provides factory-like installation and appearance
Billet steel flywheel for light weight (28 pounds) and additional strength
Roller style pilot bearing offers improved shifting by reducing parasitic drag and transmission wear

Adjustable Hydraulic Release Bearing offers reduced pedal effort and easy installation
Works with OE (original equipment) or MSD High Torque starters
All hardware included
