High quality designed springs is required to transfer the exact movement of the camshaft to the valves at high engine speeds on high performance engines. The TOMEI products are always engineered with precision in mind to suit the user's needs. So with this in mind careful choices in material selection is made with surface coating and other technologies. Then the pre-production products are put through an extensive testing program for checking durability, quality and performance. We spend time and money to help you save your valuable time and money.

Features:

  • Multi Coil Unequal Pitch Springs- By combining several steps of spring rates into the one spring and vibration frequency becomes amazingly high. This greatly minimizes resonance and the chances of surging.
  • Advanced Oil Tempered Chromium-silicone Alloy Steel Core- Oil tempered chromium-silicone alloy steel wire is used which is considered to be the best material for springs for performance applications and evolved it even further. Combined with a new optimized design, not only did we make it tougher, we also succeeded in suppressing valve jumps or bounce even when raising the engines speeds RPM limit.
  • Nitriding- The surface treatment method for making nitrogen permeates the spring and gives it large surface compression repulsion. This method was chosen to raise the fatigue limit to suit the demands or running high lift camshafts. The dangers of spring failure is greatly reduced with the 1.5 times increase in the springs fatigue limit with the combined use of Oil tempered chromium-silicone alloy steel wire and Nitriding. This is how our valve springs are suitable for use on extreme engine speed conditions of super-high revs exceeding 10,000 RPM which had not been previously possible with high lift camshafts.
  • Shot Peening-A process that strikes many small steel balls onto the surface of the spring at high speeds is made to enhance the surface of the spring to raise its fatigue limit. Although it has been carried out earlier during the manufacturing process.
  • Warm Setting- The process that is adding higher loads beyond the actual limits to the highly heated spring. This will modify its shape and keep it permanently fixed. We succeeded in securing the highest performance over a long period of time while preventing sagging.
  • Oval Wire- Using highly durable oval wire allows the valve springs to compress even further whilst still retaining sufficient force. Compatible with many high lift camshafts, these springs provide reliable performance even under load at higher RPMs. Oval wire valve springs feature greater compression than regular valve springs, allowing them to work with a wider range of 'lift' settings. This makes them compatible with both stock AND aftermarket high lift camshafts. (VR38/VQ35/KA24/4G63/4B11/G4KF)

Best money ever spent!
Color: Brown, Size: 6 Panels
I LOVE this divider! I live in an apartment with a covered patio that faces the parking lot and desperately needed some privacy. I was hesitant about ordering this due to mixed reviews but I'm so glad I took a chance. I bought the six panel in brown and it came in perfect condition, covers the entire opening, it's lightweight but sturdy enough for wind. In the 5-6 months I've had it outside it only blew over once in a hurricane and that was my fault. I should have taken it down, I knew the storm was coming...but no damage was done! It looks amazing and now I can go out on my patio day or night with complete privacy. If you're on the fence as I was, get it! Great product!

Buyer beware!
Color: Off White, Size: 6 Panels
Beware not at all a good quality. Screen is made of a very fragile product. Very cheap looking not at all anything I would want in my home. And once you have purchased it basically it is yours because Amazon can't help you because it is a third party seller. Which means you have to work with the seller directly and they want you to send it back to them on your dime to California which would almost cost the same as the purchase price.
