Single Spring/Titanium Retainer kit

Brian Crower spring and retainer kit will ensure that you are not getting any unwanted valve float if you have upgraded cams or are revving your engine higher. The springs are wound from a high-grade chrome silicone alloy that features a proprietary process to keep pressures consistent.

The springs are an OEM replacement, so no additional machine work is needed for install.
