YELLA TERRA ULTRALITE - SHAFT MOUNT- STREET RACE ROCKERS <click to enlarge>
Late model engines utilizing lightweight valve train components and conical springs are susceptible to valve float when some performance camshafts are used.
Terra developed shaft and pedestal systems for these engines that have
less than half the nose weight of other rocker designs. The result is greater
RPM potential without sacrificing strength or reliability. Standard and high
ratio options are available.
Recommended maximum spring pressure 450 lbs
