ThunderMax Cams by Red Shift are designed to deliver unmatched performance and smooth, linear power with great valve train dynamics. ThunderMax cams are ground from one-piece 8620 steel billets utilizing the latest manufacturing techniques. Available in standard splined gear chain drive, or configured for use with S&S Gear-Drive gear sets. Red Shift recommends new cam bearings and performance tappets with any cam change. All ThunderMax cams require adjustable pushrods; spring work required unless otherwise noted as a bolt-in cam. Gear drive camshafts are supplied as a cam-only kit with front and rear cams only. For cam drive gears, as well as required gaskets, bearings and other hardware, see below.

Notes:

•Make sure you select the right cam for the job. Increasing compression ratio and/or displacement beyond the recommended range for each cam will increase cylinder pressure, which makes the engine harder to start and more likely to ping or detonate. Lower compression ratios or displacements will weaken performance at low and mid range RPM.
•A hydraulic press and other professional tools are required to install cams in Twin Cam engines. Additionally, material must be removed from the inner surface of the stock gear cover to install the S&S Gear Drive.
•New cam bearings and a new gear cover gasket are required to complete this installation. These parts are provided in the Camshaft Installation support kit. If updating from the stock Silent Chain drive system on 1999 thru 2006 models (except 2006 Dyna), order 1 set cams, 1 cam gear drive kit ZPN721948 and a Camshaft Installation Support kit ZPN721950
•If updating from the stock roller chain drive system on 2006 Dyna or any 2007-2017 Twin Cam model, order 1 set cams, 1 cam gear drive kit ZPN750871 and a Camshaft Installation Support kit ZPN750873
•Due to the characteristics of gear drives, you may experience some valve train noise.
