Rocker On Shaft - 1.650 Long .050 LH Offset

The T AND D MACHINE Rocker On Shaft – 1.650 Long .050 LH Offset (Part #14-1293-180) is a precision-engineered rocker arm component designed for high-performance engine builds. This left-hand offset rocker arm is engineered for shaft-mount installation and delivers the geometric accuracy required in competitive and performance automotive applications where valve train geometry directly impacts power delivery and reliability.

The 1.650-inch length and .050-inch offset specification are critical dimensions that determine valve lift characteristics and pushrod geometry compatibility. These measurements affect how the rocker arm transmits motion from the camshaft to the valve stem, influencing valve opening and closing timing precision. Weighing 0.48 lbs with compact overall dimensions of 2.3 x 2.15 x 4.3 inches, this component integrates into tight engine bay configurations without sacrificing structural integrity. The left-hand offset orientation accommodates specific cylinder head designs and valve train layouts common in performance engine applications.

This rocker arm is suited for builders and enthusiasts working on custom engine builds, race prep, or restoration projects where original equipment specifications or performance upgrades require precision shaft-mount rocker arms with exact geometric tolerances. Buyers should verify fitment against their specific cylinder head, pushrod length, and valve train configuration before ordering. T AND D MACHINE components are known for dimensional accuracy in the performance engine community, making this part a reliable choice for builds demanding tight tolerances.

Whether you're assembling a stroker engine, upgrading an existing platform, or replacing a worn rocker arm in a performance vehicle, proper valve train geometry is essential for consistent power output and engine longevity. This left-hand offset shaft-mount rocker arm delivers the precision fit required in professional-grade engine builds.
