Tech Tips: Crower
Rocker arms play a pivotal role in maintaining peak valve train performance. Their strength and durability are essential for withstanding the high stress and heat generated in engines, especially in high-performance applications. Ultimately, sturdy rockers help deliver better overall engine efficiency and longevity.
Steel Billet Shaft Rockers
At Crower, we're always innovating. Our shaft rocker systems are specifically designed for the latest "hot" cylinder heads. Each Crower Shaft Rocker setup is meticulously engineered and manufactured to deliver maximum valve train rigidity and precision.
We use the longest possible arm length for each application, minimizing rocker tip travel. This design approach reduces frictional power loss and accommodates larger diameter valve springs. Plus, our setups make "at the track" valve train modifications a breeze. You can make any changes that require rocker removal, knowing you can reassemble with absolute accuracy.
For extreme horsepower applications of 1500 and above, we recommend our Crower Steel Billet Shaft Rockers.
Shaft Mounted Stainless Steel Rocker Arms
For those who prefer a steel-based valve train, Crower offers a range of shaft-mounted stainless steel rocker arms. Each configuration is painstakingly designed to provide exceptional rigidity, accuracy, and optimized moment of inertia. Our engineers prioritized ease of installation and maintenance, ensuring you can work efficiently when time is critical at the track.
Stainless steel's durability in high-temperature conditions makes it an ideal choice for demanding applications like dirt late models and marine endurance racing. Stainless steel components provide superior resistance to heat induced material integrity deterioration compared to aluminum, ensuring longer life in extreme conditions. Plus, our shaft rocker systems are available with a needle bearing, bushed, or DLC-coated pin tip option for enhanced performance.
Needle Bearing Tip Option
Crower has advanced valve train technology with a needle bearing roller tip, bushed, or new DLC-coated pin option, now available on all Crower stud and shaft mount rocker arm assemblies. This lighter tip enhances valve control for higher RPMs and promotes valve spring longevity by reducing heat compared to traditional designs.
The needle bearing design minimizes friction, resulting in increased horsepower and less wear on the valve guide and stem. The DLC-coated pin further reduces friction with fewer moving parts. This race-proven technology has been shown to extend component life.
