Supertech 5.5mm Diameter Lash Cap, 2.5mm Deep, 1.21mm Thick for Racing Valves - LC-55-1.21P

If you’re diving into the world of racing, you know how crucial every little detail can be. That’s where these lash caps come into play. They’re designed to boost the diameter of those slender valve tips, which is especially handy for race engines that sport those skinny 6 or 7mm valves. What does that mean for you? Well, it gives the nose roller of your rocker arm a bigger footprint to work with, which can make a noticeable difference in performance. Trust me, when you're pushing your engine to the limit, every bit of stability helps.

Now, let’s talk about Supertech. These folks are not just another name in the racing game; they’re known for cranking out top-notch valves and valve train components that cater to just about every type of motorsport out there. Whether you’re tearing up the drag strip, navigating tight rally turns, or hitting the road course, Supertech has got your back. And if you happen to have a unique setup that needs a little extra love, they’re more than willing to work with you to whip up a custom solution that fits your needs perfectly.

Just a heads up, though—when you’re checking out the product images, keep in mind they’re mainly for marketing purposes. The actual product might look a bit different, but rest assured, the performance is what counts. Speaking of specifics, these are the LC-55-1.21P lash caps, measuring in at a 5.5mm diameter, 2.5mm deep, and a solid 1.21mm thick. It’s all about that precision to help you squeeze out every last bit of power from your engine.
