Trend Performance unveils a new rocker shaft for 5.7L and 6.1L high-performance Hemi engines. Its advantages are strength, reduced friction, and affordability. The shafts will be sold through Livernois Motorsports of Dearborn Heights, Michigan.
Created to overcome deflection and to improve valve-train stability when used in conjunction with high-performance camshafts and valve train, Trend produces this new shaft from thick-wall 4130 chrome molybdenum, subjects it to two heat treatments—through-hardening and nitriding—and finally applies a DLC (diamond-like coating).
The nitriding process not only contributes a tough surface skin (.015in deep) but also produces the ideal surface for the application of the DLC. The DLC provides increased wear-resistance and reduced coefficient of friction. The 4130 chrome molybdenum material is selected not only for its strength and excellent heat-treatment properties but also for its ability to facilitate a fine surface finish of .5 micro inches (Ra—roughness average).
With a diameter and length of .865in and 19.3125in respectively, the new shaft directly replaces the original (contained within the Mopar rocker assembly, Part Number 053021574AA). Shafts are equipped with correct mounting holes, oil holes and expansion plugs installed at the ends.
