These flex plates are available to suit Ford small block and Chevrolet V8 engines and they provide the starter ring gear when used in conjunction with button flywheels. Whilst a button flywheel and flex plate installation can neither match the inertia or strength of a Tilton flywheel with integral ring gear they do provide a cost effective solution for engines not exceeding 8000 RPM and provide condsiderable reduction in inertia and saving in weight over an O.E. flywheel.
They are suitable for use with our button flywheels for both 5 1/2" (140mm) and 7 1/4" (184mm) clutches.
The Chevrolet fitment flex plate has a 153 tooth ring gear and the Ford V8 unit a 157 tooth ring gear, we offer two versions of the Ford flex plate one neutral balanced and a another with a 28oz external balance.
