Supertech 5.5mm Diameter Lash Cap, 2.5mm Deep, 1.31mm Thick for Racing Valves - LC-55-1.31P

If you're looking to boost your valve performance, these lash caps are a solid choice. They’re designed to increase the diameter of those slender valve tips, which is especially helpful if you’re running a race engine with those skinny 6 or 7mm valves. What that means in practical terms is that the nose roller of your rocker arm gets a larger footprint to work with, allowing for smoother operation and better overall performance.

Supertech isn’t just any name in the racing world; they really know their stuff when it comes to valves and valve train components. Whether you’re tearing up the drag strip, navigating rally courses, or hitting the road course, they’ve got you covered with parts that are tailored for just about any racing setup you can think of. And if you can’t find exactly what you need off the shelf, they’re more than willing to work with you to create a custom solution that fits your specific requirements.

Now, let’s talk specs: the LC-55-1.31P lash cap has a diameter of 5.5mm, with a depth of 2.5mm and a thickness of 1.31mm. It’s built to handle the demands of high-performance engines, so you know you’re getting something reliable.

Just a heads up: the images you see are for marketing purposes, so the actual product might look a bit different. But trust me, what you get is going to deliver the goods.
