A new budget upgrade kit from Lunati utilizes captured roller bearings and billet trunnions to upgrade stock GM LS rocker arms.

This kit improves valve train durability and increases lift while simplifying the trunnion upgrade process. It is the perfect option to increase rocker stability and stiffness in modified and high-performance applications. The kit is proven for use in NASCAR LS spec engines, but also serves as a DIY upgrade for home builders and is compatible with all stock rocker geometry. A magnetic installation tool is also available that makes one-handed installation a snap, and its cylindrical construction makes it easy to use in an arbor press, vice or c-clamp.

Part Number: #854219K (Kit); #85429-TOOL (Install Tool – Not Pictured)
Street Price: $137.95 (Kit); $34.95 (Install Tool)
