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
