Before you install
Don’t install this kit on stock cams — the Single/Double Spring kits are designed for Piper’s performance grinds (BP270 / BP285 / BP300 / BP320). Running stock cams with these springs adds unnecessary valvetrain load. Call us if you’re unsure which spring goes with which cam.
Order terms
Pair with the right Piper cams
Spring kits are sized to specific grinds. Call us before ordering if you’re unsure — we install these daily.
