Kibblewhite Valve Spring Kit
Fit:
-17+ Honda CRF450R
These valve springs are highly recommended for most applications.
Kit includes: Dual Spring Kit, Titanium Retainers, and Steel Base Washers.
These valve springs are good to .440" of valve lift on the intake and .405" of valve lift on the exhaust. These springs also include titanium retainers for the lightest retainer possible, allowing for increase RPM and lighter spring forces. Sunk guides are required with higher lift camshafts.
