Unlock More Lift

Unlock More Lift

Big camshafts, high valve lift, and serious RPM demand a valvetrain that stays under control. COMP Cams Max-Lift BSR Shaft Rocker Systems will keep your LS valvetrain stable when you’re gunning for maximum horsepower.

Unlike conventional individual rocker arms, the Max-Lift BSR design ties the rockers together with a rigid shaft assembly that reduces flex and deflection under extreme loads. The result is more consistent valve motion and improved valvetrain stability when running aggressive cams,high spring pressures, and high RPM. The Max-Lift BSR shaft rockers are available for GM LS7, LS3/L92, and LT engines.

Light the Fire

When it’s time to turn up the power, FAST XR Series Ignition Coils give GM LS engines the spark energy required to light the densest air/fuel mixtures to make big power.

XR Series coils generate 15-20 percent more spark energy than stock coils for nearly 50,000 peak volts. The increased output prevents misfires under load, improves combustion efficiency, and supports horsepower gains by ensuring a complete fuel burn. Installation is quick and hassle-free on most GM LS engines thanks to a direct-fit design and OE-style connections.

Dial In the Spark

Building power on engines equipped with an Edelbrock Pro-Flo EFI and EZ Street EFI System is extra easy with an Edelbrock Pro-Tuner EFI Distributor. It delivers the precise timing signal needed to help your EFI system maximize performance.

Pro-Tuner Distributors feature precision-machined housings with hardened steel shafts and sealed upper ball bearings. A Hall-effect magnetic pickup provides a clean, stable timing signal for quicker starts, crisp throttle response, and consistent power delivery at all RPMs. The melonized steel gear works with hardened steel or roller camshafts. The distributors are available for AMC, Chevy, Chrysler, Ford, and Pontiac V8 engines.
