Overview

The Texas Speed & Performance 1.72:1 Ratio Steel Roller Rocker Arm Set is a valvetrain upgrade designed for LS cathedral-port cylinder heads. These rocker arms offer improved strength over factory setups and feature a roller tip to reduce wear and friction.

They are intended as a bolt-on application for LS1, LS2, and LS6 engine applications and work with factory rocker arm pedestals. This set includes the TSP Trunnion Upgrade Kit with quality bearings for longevity. Note that installation requires a change in pushrod length, approximately .140" shorter than stock.

The Texas Speed & Performance 1.72:1 Ratio Steel Roller Rocker Arm Set is a durable valvetrain upgrade engineered for LS cathedral-port cylinder head applications. Constructed from steel, these rocker arms provide superior strength compared to stock components. The roller tip design minimizes wear and friction on the valve tip, contributing to enhanced reliability. It is intended as a direct bolt-on for LS1, LS2, and LS6 engines and is compatible with factory rocker arm pedestals. The package includes the TSP/CHE Trunnion Upgrade Kit, featuring quality bearings for extended service life. Installation of this rocker arm set necessitates an adjustment in pushrod length. It is approximately .140" shorter than the stock pushrods. It is highly recommended to verify the precise pushrod length required during installation to ensure optimal performance and engine health.
