Valve Springs

Valve Springs: the part that keeps your valvetrain honest at high rpm

A valve spring closes the valve and holds the lifter against the cam lobe. When rpm climbs or you fit a lift cam, the factory spring can lose control of the valve, float, and let it kiss a piston. Upgrading your valve springs gives you the seat and open pressure to follow an aggressive lobe cleanly, and it's the job you do any time you cut a head for bigger valves or wilder cams. Skip it and you cap your safe rpm; get it right and the valvetrain stays planted.

What ThreePiece stocks

There are 225 valve spring products in this category, from 10 brands. The deepest ranges come from Supertech (77), Brian Crower (60) and GSC Power Division (49), with Skunk2 Racing, COMP Cams, Ferrea, BLOX Racing, S&S Cycle, Manley Performance and Ford Racing filling out the rest. Current in-stock prices run from $20 to about $1,819 - a live range, not a promise. Single springs sit near the bottom; complete kits with titanium retainers, seats and seals sit at the top, like the GSC Audi R8 / Lamborghini Huracan V10 kit.

How to choose

The first decision is spring style. A conical spring, like the Supertech BMW S63 conical kit or the N54 conical kit, uses a tapering coil to control resonance with lower reciprocating mass. A dual spring - spring inside a spring - like the Ferrea GT-R VR38DETT dual kit gives high pressure for boosted or high-lift builds. For serious lift, the Ferrea K20 high-lift drag kit is built for that duty, while a single conical like the GSC GT-R single conical kit keeps mass down. Match the spring rate and installed height to your cam's lift and duration - buy springs your camshaft actually needs, not the stiffest ones on the shelf.

What else you need with it

Springs rarely go in alone. Many kits already bundle retainers, seats and seals; if yours doesn't, plan for those separately. A spring job usually means the head is off, so look at head gaskets and gasket kits for the reseal, and if you're going deep, pistons and bearings while things are apart. Browse the full Engine Components section for the rest of the build.

Fitment and ordering

Only 30 products carry structured fitment data, covering makes including Subaru, Mazda, Hyundai, Nissan, Mitsubishi, Ford, Audi, Toyota, Lotus and Harley-Davidson, and vehicles from the Mazda Miata and Subaru WRX to the Toyota Supra, Ford Mustang and Lamborghini Huracan, across model years 1984 to 2024. Product names also reference Honda, Acura, BMW, Lexus, Porsche and more - always confirm the part matches your exact engine before ordering. Not sure?
