Supertech Lash Cap 5.5mm Diameter 2.5mm Deep 1.40mm Thick for Racing Engines - LC-55-1.40P

Alright, let’s talk about lash caps—specifically the Supertech LC-55-1.40P. If you’re running a race engine with those skinny 6 or 7mm valves, these little guys are a game changer. They beef up the diameter of your valve tips, which means the rocker arm’s nose roller gets a better grip. This extra footprint really helps in keeping everything stable, especially when you’re pushing your engine to its limits.

Supertech isn’t just another name in the racing world; they’ve been around long enough to know what works. Whether you’re into drag racing, rally, or road racing, they’ve got valves and valve train components that fit like a glove. And if you can’t find exactly what you need? They’re open to custom solutions. It’s like having a personal pit crew at your fingertips.

The LC-55-1.40P lash cap measures in at a solid 5.5mm in diameter, 2.5mm deep, and 1.40mm thick. It’s designed to withstand the rigors of high-performance racing without flinching. Just make sure you double-check fitment for your specific setup—because nothing’s worse than getting excited about a part only to find out it doesn’t fit quite right.
