Lingenfelter Launches GT9 HYD Roller Camshaft for LS Series Motors

8499wbThe glory of the LS motor, far from fading away since being gradually phased out of production, is going nowhere but up. Need evidence? Look no further than Lingenfelter‘s latest creation, the GT9 HYD roller camshaft. The cam works well with forced induction applications, and covers the gamut of LS series motors from LS1 to LS9 (excluding the LS4).

Official Release:

The Lingenfelter GT9 camshaft was designed Lingenfelter based on extensive engine dyno testing with our LS9 ZR1 engine. The GT9 camshaft was used in both the Lingenfelter cars that won 1st and 2nd place at the 2010 LSX Shoot out.

This cam can be used in supercharged or turbocharged applications for LS1, LS2, LS3, LS6, LS7, LS9 engines. This cam produces a smooth idle for automatic or six speed manual transmission equipped vehicles and can be daily driven.


  • Works with Gen III and Gen IV GM small-block motors (excluding LS4)
  • Produces smooth idle
  • Tested extensively in an LS9 on Lingenfelter’s engine dyno
  • 215/247 duration @ .050 lift – .629/.656 lift with 1.7 rocker 121 CL
