Designed for LS engines with mild cam swaps, the COMP Cams LS6+ Beehive Valve Springs improve upon the popular blue GM LS6 valve springs. By increasing seat pressure by four percent, the COMP Cams LS6+ springs maintain a higher level of dynamic control while also increasing maximum valve lift by 0.030" over the GM LS6 springs. The result is a COMP Cams engineered spring that outperforms the GM product in every way! These springs are ideal for use with our NSR series camshafts and factory GM performance camshafts.
