What is the advantage of the deeper pushrod seat?

The .140" deeper pushrod seat is beneficial for aggressive cam lobe designs. It helps maintain proper valve train geometry and ensures consistent operation, especially at higher RPMs where standard lifters might struggle.

What materials are used in these lifters for durability?

These lifters feature a durable axle made from wear-resistant tool steel, which is crucial for prolonging the life of the roller assembly. The needle bearings are also precision sorted by size to help evenly distribute loads and prevent premature wear.

Are these lifters compatible with all Chrysler V8 engines?

These specific lifters are designed for Chrysler V8 engines including the 383, 440, and 426 Hemi. While they fit many Mopar vehicles from the 1960s and early 1970s, it's always best to check the detailed fitment list to confirm compatibility with your specific engine and vehicle model.

Product Details

If you're building a high-performance Chrysler V8, especially one with an aggressive cam profile and aiming for higher RPMs, you'll want lifters that can keep up. These Endure-X Solid Roller Lifters from COMP Cams are built for that kind of demanding work. They're designed specifically for Chrysler 383, 440, and 426 Hemi engines, fitting a range of models from the early 60s through the early 70s, including popular choices like the Dodge Charger and Plymouth Road Runner.

What sets these apart is the pushrod seat, which is located .140 inches deeper than standard. This adjustment is crucial for aggressive cam lobes, helping to ensure proper geometry and consistent valve train operation at higher engine speeds. COMP Cams also uses a wear-resistant tool steel axle and precision-sorted needle bearings to handle the increased loads and reduce friction, which means better durability and longevity for your engine build. These lifters are heat-treated and machined to tight tolerances, and they're fully rebuildable, so you can service them down the road if needed.

The patented link bar assembly on these lifters combines the security of a captured link bar with the convenience of a removable one, making installation and setup more straightforward. If you're pushing your Mopar V8 hard, these lifters are a solid choice to ensure your valve train stays reliable.
