Now available for your M20 Engines. These billet rocker arms have been through painstaking R&D and real world use to deliver the best performance in all areas.
We have tested and run countless performance rocker arms over the years and found that none of them could truly get racers to the podium, while also being very light weight and easy on the valve-train / camshaft (this further improves output and reliability).
Our Aluminum Rockers are here to dispel the myth that heavy steel rockers are needed to maintain reliable performance and sacrifice high RPM stability.

Our rockers feature:
- Advanced metallurgy in all areas of construction
- Internal Lubrication port to directly lubricate camshaft lobes
- Larger camshaft sweep area for following aggressive camshafts
- Euro style screw and nut for lash adjustment; easier to adjust, keeps it is adjustment best
- Cam contact area is longer and easier on camshafts under stress
- Much stronger than stock, made from virgin billet aluminum
- CAD/CAM designed with FEA (finite element analysis) optimization
- Extra wide valve contact area for even stress distribution
- Lightest rockers we have ever weighed, bests all competition
- Fully rebuildable in case of engine lubrication failure
- 20% lighter than weak BMW original rocker arms
- Extra clearance for larger retainers
- Cam Pads are finished and treated to Top-Fuel racing specifications
- Each cam pad individually referenced for level of hardness and porosity.
- Higher Strength & less deflection allow use of more radical camshaft designs and offer more precise valve motion
- Unheard of: guaranteed against excessive wear, even when racing! 100% support
- Superior in all ways, the rockers are a must when running a high performance camshaft or when racing. (Suitable for street use as well)
- With these rockers, you eliminate the known weak point in the M10/20/30 series valve train, opening up room for much more power and reliability under all conditions.

When ordering please specify what manufacture camshaft will be equipped in your engine (BMW, Schrick, etc.)

These Valve Spring Kits feature a dual spring configuration capable of turning @ 12,000 RPM for that added piece of mind (Over-rev/Mis-shift, going deep into a corner).

The Dual-Spring concept,superior by design.
By having an interference fitment of two springs, harmonic resonance is dampened across the RPM range. Also, the secondary spring acts as a safety mechanism: if something should happen to one spring, the other prevents the valve from dropping into the combustion chamber. These springs are capable of handling much higher lift, even the most aggressive of cams like the Schrick 320 degree cams are no problem.

After rigorous testing in race engines over 3 years, this Valve Spring Kit still tests within 2% of their original rate. Hands down these are some of the finest springs available for any BMW.

Kit includes:
-24 High Performance Dual Valve Springs
-24 Titanium Valve Retainers
-Spring Seats (where applicable)

*Note: Due to the nature of titanium retainers, they are ideally suited for Race engines that will see consistent High RPM usage. It is only recommended they be installed in a valve train that will be inspected from time to time. Our Steel alloy retainers are a great alternative choice for a street or track oriented car whose engine will not be internally inspected often.
