These are our recommended drop in solution for boosted 2.8-3.5 LX9 engines, and naturally aspirated LZ engines. Good for 20+ psi of boost on our stage 2 turbo cam and for LZx applications, anything NA up to .600" lift will do. Boosted LZ applications can also make use of this spring and likely handle quite a bit of boost as well.
