Supertech 6mm Diameter 1.66mm Thick 2.5mm Deep Lash Cap for Racing Valves - LC-60-1.66P

So, let’s talk about lash caps for a second. If you’re running a race engine with those slim 6 or 7mm valves, you know how crucial it is to get every bit of performance out of your setup. That’s where these lash caps come into play. They basically beef up the diameter of those slender valve tips, giving the nose roller of your rocker arm a bigger footprint to work with. This means more stability and better performance when you’re pushing your engine to the limit.

Now, I’ve been around the racing scene long enough to appreciate quality components, and Supertech really delivers. They’ve got a solid reputation for providing top-notch valves and valve train parts that cater to just about every racing discipline you can think of—whether you’re into drag racing, rally, or road racing, they’ve got you covered. And if you’ve got something a bit more custom in mind, they’re totally open to working with you to whip up a solution that fits your needs perfectly.

As for the specifics, let’s break it down: you’re looking at the LC-60-1.66P lash cap, which has a 6mm diameter, is 1.66mm thick, and 2.5mm deep. It’s designed to give your setup that extra edge without compromising on quality. Just keep in mind, the images you see are for marketing purposes, so the actual product might look a bit different.

In short, if you want to enhance your valve train and get the most out of your engine, these lash caps are a solid choice. Trust me, you’ll feel the difference on the track.
