Designed for high rpm, BC valve springs by PAC Racing are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures.
| 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. |
