These quality Morel lifters are a high performance upgrade which also has the added benefit of making the flimsy factory plastic lifter trays obsolete. Besides the superior construction and materials used, the captured link bar system ensures precise lifter movement for years to come and means you'll never have a lifter spin in the bore. Made in the USA using high-quality, heat-treated metal, these lifters are designed to withstand the rigors of racing, while still offering smooth and quiet operation for the street. They do not need constant adjustment like mechanical, or "solid" lifters, making them easy to install and maintain.

Hydraulic roller camshafts and lifters (as fitted standard to these vehicles) offer a long list of important benefits over flat tappet cams: no break-in worries, excellent reliability and top notch performance. Morel's Street Performance Roller Lifters are reasonably priced thanks to modern Cold Casting Technology and offer exceptional durability and performance.

OEM & most aftermarket lifters use a swedged axle design, meaning they distort the ends of the axle for a press fit in the lifter bores. This approach simply isn't reliable or durable enough in high performance applications; such as when a high performance cam is used in your engine.

Morel instead use a wire-loc retaining system with a floating axle, much like floating pins in your pistons. This is the best deterrent to keep the axle in the bore in high performance applications, and is a huge upgrade over the swedged axle design used in most other lifters on the market.
