Texas Speed Dual Spring Cam Package for Rectangular Port Heads (LS3/L92/LSA/L76)

This package will include the following items: Your LS-3 camshaft of choice TSP Dual Spring Kit w/ PAC Polished .660" Springs, Retainers, New Seats, & New Seals Texas Speed Hardened Chromoly Pushrods 8620 Cam Core available upon request* Note: The factory LS3 camshaft uses a single-bolt cam design, which means one bolt holds the upper timing sprocket on the camshaft. For LS3 vehicles, you can either go back in with a single-bolt camshaft or convert to the three-bolt camshaft design that the 1997-2006 LS-based vehicles use. The three-bolt conversion kit will supply the correct 4x upper timing gear to supply the correct camshaft position signal, as well as the ARP camshaft bolt kit that will supply the three required bolts. We also offer the conversion kit with a complete, upgraded timing set for those wanting to replace the entire set. We have two options listed for our dual valve spring kits. The default option will use our PRC integrated one-piece seat and seal that simply pushes in place. The other option is for the separate two-piece seat and seal that you typically find in any dual valve spring kit. The two-piece kit will require separate installation of the valve seals after the seats are in place, and it does require a specific tool to make sure that the valve seals are installed properly (i.e. not crooked, torn, or not installed fully). Our integrated seat and seal will make your installation much easier because it is virtually impossible to install it incorrectly! You can choose either kit for no additional charge. We have a picture listed when you select each spring kit so you can see the actual differences in the two kits. Note: All camshafts listed will require the removal AFM/DOD, if equipped. You can purchase our DOD Delete Kit separately.
