The newest technology for LS engine builds
New Elgin ProStock valve springs for the LS Engine. When you upgrade the cam, you need to upgrade valve springs to match. The original stock springs will only handle low lift stock cams.
LSX crate engine cams and the Sloppy Mechanics Stage 2 cam need higher spring pressures for higher valve lift and improved cam lobe ramp profile.
These new beehive LS engine valve springs are rated at 125 pounds of pressure at 1.800″ on the valve seat or installed height. When the valve is open, the spring is compressed to 1.150″, and the pressure is at 367 pounds of pressure.
Beehive Valve Springs
Traditional valve springs often include an inner damper to help stabilize their oscillation. Beehive springs do not need a damper because their tapered shape gives them natural stability.
The geometry of a beehive valve spring reduces the dynamic surges by improving valve train harmonics.
Beehive and conical shaped valve springs are more complex to manufacture, so most production engines for common vehicles and applications use a traditional straight side spring.
Finish your Race Build : SUPER-Finish
Super-finished Valve Springs
Most of the mass-produced valve springs have imperfections in their surface, which is tolerable inside stock vehicles at low pressure and RPM’s.
For higher pressures and RPM’s, the surface finish needs to be micro-engineered, with a multilayer fatigue enhancement. This both eliminates potential surface defects as well as prolongs spring life.
Our proprietary heat treat process gives these springs improved strength and optimized residual stress for performance valve spring applications.
Camshaft and Valve Springs
Valve spring engineering has improved since the introduction of the E-1840-P Sloppy Stage 2 camshaft. The preferred spring has changed a couple times to match the capabilities of the cam.
The new Elgin RV-126918 valve springs are ready to handle those high-power high-RPM LS engine builds. Mate them with the Elgin one-piece thick-wall pushrod for maximum valve train stability.
