Description
Rocker arm ratio directly influences valve lift and duration—and this 1.7:1 set delivers the aggression your LS engine demands while maintaining stock-compatible geometry. The full roller design minimizes friction losses across the RPM band, translating to more power at the crank and improved throttle response. If you’re running a built LS platform or chasing peak efficiency on a stock rebuild, these adjustable arms give you the tuning latitude to dial in valve train geometry without custom fabrication.
