The Texas Speed Gen III 6.4L Hemi Rocker Stabilizer Kit locks the rocker shaft stands on a 6.4L Hemi in place so the shafts hold position under high horsepower and high rpm. As spring pressure and engine speed increase, the factory rocker stands can shift and flex, and Texas Speed machines these stabilizers from high-grade steel to brace them and keep rocker geometry steady.
The kit supplies ten stabilizers and sixteen rocker shaft collars for both cylinder heads. Texas Speed states the stabilizer and collar combination virtually eliminates the possibility of a rocker-related valvetrain failure in high-performance driving, and installation is a straightforward bolt-on with no cylinder head machining. Unlike the 5.7L version, Texas Speed lists no valve cover modification note for the 6.4L kit.

FAQ
What does the Texas Speed 6.4L Hemi rocker stabilizer kit do?
It braces the rocker shaft stands on a Gen III 6.4L Hemi with steel stabilizers and adds collars to the rocker shafts, preventing shaft movement under high spring pressure and rpm so the valvetrain remains stable.
What comes in the 6.4L stabilizer kit?
The kit includes ten high-grade steel rocker stabilizers and sixteen rocker shaft collars, covering both cylinder heads on a 6.4L Hemi.
Does this kit fit the 5.7L Hemi?
No. This kit is designed for the Gen III 6.4L Hemi. Texas Speed sells a separate kit, part number TSP-57HEMIVSK, for the Gen III 5.7L Hemi.
Is any machining or modification required?
Texas Speed describes installation as bolt-on with no machining. The 5.7L version of this kit requires valve cover modification, but Texas Speed does not list that note for the 6.4L kit.
When should a 6.4L Hemi get rocker stabilizers?
Texas Speed recommends them for higher horsepower and higher rpm applications, such as cammed or forced induction 6.4L builds, where rocker stand movement can cause valvetrain failure.
