Roller Lifters - BBM 426 Hemi/440B

CROWER Roller Lifters for BBM 426 Hemi and 440B engines are designed for serious engine builders looking to maximize performance and reliability in classic American muscle vehicles. These lifters are particularly suited for high-RPM applications, making them ideal for street machines, drag racing builds, and restomod projects.

Engineered to reduce wear patterns and friction losses, these solid roller lifters provide superior valve actuation compared to traditional flat-tappet designs. The roller configuration minimizes friction at the camshaft lobe contact point, leading to improved power output and extended engine life. CROWER's precision manufacturing ensures tight tolerances within the pushrod bore, which is critical for maintaining valve timing accuracy.

These roller lifters are perfect for engine builders who are restoring or modifying 426 Hemi and 440B engines, allowing for steeper ramp rates on cam profiles. This capability enhances combustion chamber filling and scavenging, which are essential for achieving increased displacement efficiency. Whether for performance builds or competitive racing, these lifters are a reliable choice.
