Description

These engines has very soft standard valve springs so these are highly recommended for any cam upgrade that is worth installing.

Straight drop in replacement. Other springs on the market from dubious sellers require you to use shims (washers) to obtain correct free height. Don’t risk buying inferior springs. These are the best available on the market.

These are a must for once you go moderate boost levels so the valves stayed seated at high rpm and boost levels. You will have a much more responsive engine and not receive any power loss with the weak stock springs when seeing boost pressure.

Supports up to 11.8mm lift, 86lbs seated tension and 215lbs tension at 11.8mm lift. Required with any camshaft upgrade with turbocharged engine.
