Supertech Lash Cap 5.5mm Diameter 2.5mm Deep 1.38mm Thick for Racing Valve Tips - LC-55-1.38P

If you're diving into the world of racing, you know that every little detail counts—especially when it comes to your engine's performance. That's where these lash caps come into play. Designed specifically to increase the diameter of those slender valve tips, these little guys are a game changer 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. More contact means better stability and improved performance, which is exactly what you want when you're pushing your machine to the limit.

When it comes to quality, Supertech is a name that stands out in the racing community. They’re not just about valves; they’re all-in on providing top-notch valve train components that cater to every kind of motorsport you can think of—be it Drag Racing, Rally, or Road Racing. And if you can’t find exactly what you need off the shelf, they’re more than willing to collaborate with you to whip up a custom solution that fits your specific setup. It’s that kind of dedication that makes a difference on the track.

Now, let’s get into the specs. You’re looking at the LC-55-1.38P model, which features a 5.5mm diameter, 2.5mm depth, and a thickness of 1.38mm. These dimensions are crafted to make sure you get the most out of your setup, ensuring that everything runs smoothly when you’re in the heat of competition.

Just a heads up: The images you see are for marketing purposes only, so the actual product might differ a bit. But trust me, when you feel the difference these lash caps make, you’ll know you made the right choice.
