Exhaust valve Kit NISSAN 300/VG30D 3.0L DOHC/300 ZX 90-96The production of our race valves begins with a one piece forging where the valve head is forged in a slow two step process to maintain a good material flow. Then it is machined on the CNC in several stages to ensure the precision of the final dimensions. Then, we perform another thermal treatment for relaxation, followed by nitride curing (or coating process depending on the application). Finally, we perform one more grinding followed by a patented

The production of our race valves begins with a one-piece forging where the valve head is forged in a slow two-step process to maintain a good material flow.

Then it is machined on the CNC in several stages to ensure the precision of the final dimensions.

Then, we perform another thermal treatment for relaxation, followed by nitride curing (or coating process depending on the application).

Finally, we perform one more grinding followed by a patented surface finish to ensure that each valve is free of imperfections and the dimensions are precise.

With each valve design, we strive to maximize durability due to the higher resistance to fatigue and tensile strength.

Each valve tip is hardened above 52 HRc.

It is unlikely that you will find valves from our competitors with stricter dimensional tolerances than our Supertech valves.

Combine it with ready valve seats with equally strict tolerances and you will not find better sealing, better performance and easier to install solutions anywhere!

When our Superfinish coating is combined with our black nitrogen, it reduces the surface roughness to 1/3 of our chromed valve.

The end result ... unmatched performance and durability./p>

Easy to install, very tough!

Seriously, scoring these shelf stands for $30 feels like an absolute steal! Four chunky wood boards with metal T-brackets that actually feel substantial - way sturdier than those flimsy IKEA ones I used to have. My old cheapo stands warped after half a year, but these hold up like a champ - I've got like 15 heavy textbooks stacked on them right now. Love the little details too: rounded edges so you won't scrape your hands, and rubber grip strips on the bottom. They look legit fancy in my living room as bookshelves and even class up my kitchen herb garden. My friend thought they were some high-end designer furniture! Honestly, the craftsmanship at this price puts my old $60 wooden shelves to shame. Already told my DIY group chat about these - trust me, you can't go wrong!

Worst item ever
Color: White, Size: 16in
Set up shelves and not sturdy at all. Followed the instructions perfectly. Very poorly made. I don’t have the box and now I’m stuck with the item. Garbage can here it comes.
