Brian Crower 80lbs K20A K20Z Dual Spring & Titanium Retainer Kit (No Seats)

Designed for high rpm, BC valve springs are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. BC titanium retainers are CNC machined from 6AL4V round bar titanium to exacting tolerances.

If you have a K20A2, you can use these springs and retainers with your factory spring seats. You cannot use K20A3 spring seats with these springs though. So if you have a K20A3, you will need to purchase BC0040S or BC0040
K20A / K20Z VALVE SPRING & RETAINER KITS
Designed for high rpm, BC valve springs are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. BC titanium retainers are CNC machined from 6AL4V round bar titanium to exacting tolerances. Use steel retainer for high mileage applications.

WARNING: If running a late model cylinder head (after 2004), you may need to purchase BC2940 keepers to accommodate the BC2010 or BC2011 retainers. Honda changed the keeper groove angles, therefore your stock keepers/locks may not fit the BC retainers properly causing potential damage.
