Description

Holley transmission installation kits come complete with everything you need to bolt a TKX or TKO transmission to a 28- or 50-ounce externally balanced small-block Ford engine (depending on kit selected). Built with a mixture of best brands (such as Lakewood, Hays, and Mr. Gasket), the kits include: a roller pilot bearing, bellhousing with dust shield, billet steel flywheel, clutch and pressure plate, hydraulic release bearing, and all hardware needed to install these components.

Additional features and notes:

* Lightweight cast aluminum bellhousing and steel block plate provide a factory-like installation and appearance
* Billet steel, 24.5 lb., 157-tooth externally balanced flywheel for light weight and strength
* 26-spline, 10.5 in. clutch disc offers superior clamping force for engines up to 500 hp
* 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 or MSD high-torque starters
* All hardware included
