998/1049 lightweight valve spring kit, titanium retainer

$410.00

This is the kit we recommend for trail applications. The 998 engine will easily dislodge valve shims when hitting the rev limiter and inducing valve float, and this upgrade goes a long way to helping prevent that issue. it is also a mandatory upgrade if doing one of our camshaft kits as the stock springs are not strong enough. 
This kit uses dual springs and lighter titanium retainers.


NOTE: if you are racing and using any form of antilag, we suggested upgrading to the shim in tappet kit.
