LS SERIES ROLLER ROCKER ARMS
YELLA TERRA ULTRALIGHT
Late model engines utilizing lightweight valve train components and conical springs are susceptible to valve float when some performance camshafts are used.
Yella
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 425lbs
PLATINUM RACE ROCKERS
Designed for the most severe race applications Platinum rockers feature “wide body” arms for even greater strength and resistance to deflection. All platinum rockers feature heavy duty 7/16” mountings for unsurpassed rocker stability.
Recommended maximum spring pressure 900 lbs
ALL YELLA TERRA ROCKERS ARE
BILLET ALUMINUM - DESIGNED FOR DROP-IN INSTALLATION
COMPLETE WITH ALL NECESSARY HARDWARE - LIMITED LIFETIME WARRANTY
