Super high performance Beehive Profile Tool Room™ Valve Springs that will handle up to .625 lift as a drop-in replacement for the Stock Beehive spring. This spring is compatible with stock retainers and locks, but we highly recommend for increased performance, the use of our 135-ST steel retainer and VL-500 Machined Bead Locks.
