Engine Valve Technology

Supertech applies more than 30 years of experience in the development of each and every Supertech racing valve sold. Combine this experience with state of the art equipment such as ultrasonic tests, x-rays, laser measurement equipment, and applications like computerized Finite Element Analysis (FEA) and it is no wonder why Supertech has some of the best performance products on the market.

Supertech also does extensive testing working very closely with many of today's top engine builders in order to continuously improve products. All of this is meant to insure Supertech's industry leading reputation for high flow rates, durability and uncompromising quality.

Higher Flow Rates

Supertech valves are not finished from generic blanks rather they are specifically designed for each and every application. Supertech works relentlessly, testing and researching every aspect trying to improve the air flow of their designs.

Durability

With every valve design, Supertech strives to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc.

Stem Super finishing

In 2006, Supertech introduced the stem Superfinishing as a standard addition to all valves and provided it at no additional cost. When Superfinish is combined with our Black Nitrided valve it reduces the surface roughness to 1/3 of a chrome coated valve. The end result... unsurpassed performance and durability.

Strict Dimensional Tolerances

It's unlikely you will find any of competitor valves with stricter dimensional tolerances than Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere!

Excellent toy for active dogs! Five ⭐️
Color: Green
⭐⭐⭐⭐⭐ Excellent Toy for Active Dogs! This is my second time purchasing this toy, and it absolutely deserves five stars. My youngest dog, Captain, is a very active 3-year-old with more energy than I can keep up with. He loves being able to sink his teeth into this squeaky toy, and it helps keep him mentally stimulated and entertained. What I love most is that he also shares it with his older brother, Kane. They use it for tug-of-war, which helps burn off some of Captain’s endless energy and keeps both dogs engaged. It does a great job reducing boredom, especially for highly active dogs. The first one lasted several months before needing replacement, which is impressive considering how much it was used. If you have energetic dogs that need something durable and fun, I highly recommend this toy!

Perfect Pup Pal
Color: Green
I purchased this dog toy as a birthday gift for a friend's dog, and it exceeded all expectations. Knowing she is particular about toys and easily frightened by many, I spent quite some time choosing the perfect one. From the moment she took it out of the box, she adored it. Everyone at her birthday party was amazed. Watching her happily play with her new toy, which we've come to call Allie, is truly heartwarming. The quality is outstanding. It is well made, safe, and nearly indestructible, yet gentle enough on her mouth. I will definitely be buying more from this store.

Awesome toy!! Labrador Retriever approved
Color: Green
I bought this for my nephew’s Labrador retriever. He pulled it out of the bag and immediately started taking it around for everyone to throw around and play tug a war with. He played with it for hours outside (it definitely needed washing lol). Its durable showed no signs of tearing. I would definitely recommend this!!

Cute but not for a super chewer
Color: Green, Color: Green
It’s a super cute toy. My boy loves the squeaker toys and he’s a fast chewer. Unfortunately for him, he tore it up within 24 hours. It’s definitely not for super chewers but he had a good time with it while it lasted!

Durable & Leather. For Small-Medium Dogs
Size: 15 in, Color: Retriever, Size: 15 in, Color: Retriever
This is a great dog toy! My Pomeranian is a small guy at only 8lbs. but he sure knows how to chew and he does it as often as he can. I was throwing out toy after toy because he was tearing them to pieces after only a half hour or so. After putting my money in the garbage so many times, I decided to search for toys that would hold up to his destructive mouth. I found a lot that claimed they wouldn't fall apart but they were all more than I wanted to spend. I came across this toy and a rabbit shaped one just like this. I bought both months ago and both are still in tact after all this time. Sure the edges are a little frayed but other than that, no damage whatsoever! I'm not sure what dura fused means but that seemed promising to me when I was reading the description, also the fact that they're leather made them seem more durable to me. Both have squeakers inside and some sort of stuffing as well. I throw all of my dogs toys in the laundry or hand wash them once a week, except for these. When these toys get wet with my dogs saliva, they look like they're not meant to get wet. Even without washing, these seem fine. This toy is probably about 9" long or so if I had to guess. In my opinion, it'd be perfect for a medium sized dog. It's a tiny bit big for my little guy but he manages just fine! If you're looking for a durable toy that your small to medium dog can chew on constantly, look no further!
