On thing that’s often overlooked when modifying an LS engine is the rocker arms. After all, the LS rockers are some of the best valvetrain components that GM has ever produced so why bother? Well, here are a few of reasons. 

Cheap Insurance

Even though the high-mileage rockers look good, they may not be. The weak link of the factory rocker is the fulcrum assembly itself and not necessarily the rocker arm. GM utilized an open design which means trouble when the rockers get fatigued and worn out. The result of this would be bearing parts floating around in the engine which could be catastrophic to an existing build or a new one. Plus, if you’re running a larger camshaft, the valvetrain is having to take the brunt of the higher lift cam and compress the the heavier springs. 

Cost Effective

PRW Industries offers an affordable yet effective solution. For only $99.50 you can purchase a complete LS fulcrum replacement kit. It will include everything you need to convert the factory setup to a more robust design that will allow you to run a larger cam and springs without the worry of valvetrain failure. The new fulcrum kit, which includes, replacement fulcrums, drawn cup bearings, circlips, and fasteners for a full set of 16 will convert the components to a captured design. This will make sure that all of the bearings will stay put and increase the strength of the rocker. 

Simple Installation

As you can tell by the two-minute video, this process is pretty straight forward. It only takes about an hour to completely modify your factory LS rockers with the PWR installation kit. This is a very simple conversion and includes everything you need for the rocker modification. All you need is a few simple hand tools and vice to complete the process.
