*L5P fitment read notes below*

Whether your truck is a daily driver or a race truck, this valve spring kit will handle it all. A simple upgrade like engine tuning can raise the engine RPM and boost pressures. The stock spring design tends to oscillate at high RPM's which puts a lot of stress on valvetrain components. When the stock springs get weak or pushed past their limits, they can stay open when they're not supposed. This will result in performance loss and can cause damage as well. Conical valve springs naturally dampen and reduce oscillation without creating more heat and friction. The result is a longer valvetrain life expectancy, ability to handle higher pressures, all while reducing weight compared to the standard spring design. This spring kit is perfect for replacing stock worn springs all the way up to 2,000HP race engines and everything in between.

Features:

  • Unique Conical Design
  • Increased Spring Stability
  • Increased High RPM Capability(rated for 6,500RPM)
  • Billet Steel Retainers(reduced weight while doubling strength)
  • Nano-peened spring surface for reduced stress
  • Steel spring cups to prevent cylinder head wear
  • 130LB. installed seat pressure @ 1.610"

Includes:

  • Conical Valve Spring Set
  • Billet Steel Retainer Set
  • Chromoly Spring Seat Set

Notes** If you are installing this kit on a L5P, you won't be using the springs cups. The valve stem seals act as a cup to keep the spring positioned from moving around.*
