Trend Performance has introduced a new rocker shaft for 5.7L and 6.1L high-performance Hemi engines that offers strength, reduced friction and affordability. The shafts will be sold through Livernois Motorsports of Dearborn Heights, MI.
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 carbon) coating.
The nitriding process not only contributes a tough surface skin (.015˝ deep), but also produces the ideal surface for the application of the DLC coating. The DLC coating 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 .865˝ and 19.3125˝ respectively, the new shaft directly replaces the original (contained within the Mopar rocker assembly, p/n 053021574AA).
This new Trend shaft is equipped with all the correct mounting holes, requisite lubricating holes and freeze plugs installed in the ends.
