BRIAN CROWER VALVE KEEPERS LOCKS

 
K20A / K20Z / K24 - VALVE KEEPERS / LOCKS
7° billet performance valve stem keepers or locks are designed to fit BC retainers (BC2010 and BC2011). Precision machined from premium billet bar stock chromoly steel and heat treated for maximum strength to insure against shoulder shearing (common with stock and lesser quality brands).
 
BC2940 7° Billet Keepers / Locks for 5.5mm Honda / Acura 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.
