WHY TO BUY?
The small components in your engine are just as crucial to performance as some of the larger more glamorous parts. Your GMC S15 rocker arms are in charge of opening the intake and exhaust valves so that gas can flow smoothly in and out of the combustion chamber. If your rocker arms are worn out or damaged they can cause a loss of power, overheating and even lead to total engine failure. Here at Andy's Auto Sport we have a full line of replacement GMC S15 rocker arms to keep your engine running strong. Whether you want simple OEM replacements or high performance units you are sure to find the perfect GMC S15 rocker arms for your application in our vast lineup.

DID YOU KNOW?
One way to significantly boost horsepower is by reducing internal engine friction. There are several companies offering high-performance GMC S15 rocker arms with roller bearings to allow for smoother operation and increased power. High-performance rocker arms are also available in custom lengths that allow intake and exhaust valves to open further which in turn increases flow through the cylinder head. These high ratio rocker arms will make a pronounced improvement in power that can mean the difference between winning and losing on the track. Although small in size, rocker arms are incredibly important to your engine performance.
FAQs
Q: What are rocker arms? Why buy them?
A: Rocker arms are the part of your valve train that acts directly to open and close your valves by translating inputs from the camshaft. Worn out rocker arms can drastically impact performance. Valve clearance can be thrown out of whack causing the valves not to open far enough leaving your engine with serious breathing problems. A new set of rocker arms will have your motor running like a top and maximize both power and reliability. There are a host of performance rocker arm options available as well. High-ratio rocker arms feature a longer lever that allows your valves to open further than before and thus they increase flow through the cylinder head. Roller rockers feature roller bearings on the contact end of the arm which reduces friction during operation and frees up extra power. Some rocker arms feature both an increased opening ratio and roller bearings giving you the ultimate in a performance rocker arm. With light weight designs and good performance gains these aftermarket rocker arms are hard to beat.
