JP Performance make a large range of timing chain sets for V8's, six and four cylinder engines. They are machined from billet steel and turned for greater accuracy on CNC machinery. To see how they are made follow this link. It is advisable when installing a new timing chain or gear set to use a degree wheel to dial-in the camshaft. To do this use the JP Performance Degree Wheel (JP 5720) which includes instructions on the face. All JP Performance Timing Chain Sets are supplied with induction hardened and multiple keyway crank sprockets (which have the keyways index marked for easier timing) and balanced camshaft sprockets and a true roller timing chain. Also all sets for engines without factory fitted thrust plates (i.e. Chevy V8's and Chrysler big block V8's) are machined with a reverse oiler groove. For those that require a Torrington bearing fitted (such as race engines) then we also have them available. Sets fitted with the Torrington bearing are marked 'T'. .
