The Texas Speed Gen III 5.7L Hemi Rocker Stabilizer Kit braces the rocker shaft stands on a 5.7L Hemi so the shafts stay put under high horsepower and high rpm. Hemi rocker shafts are held by stands that can shift and flex as spring pressure and engine speed climb, and Texas Speed builds these stabilizers from high-grade steel to lock the shafts in place and keep the valvetrain stable.
The kit includes ten stabilizers and sixteen rocker shaft collars. Texas Speed states the combination virtually eliminates the chance of a rocker-related valvetrain failure in high-performance use, and installation is a bolt-on job with no machining to the heads. One point to plan for: the factory 5.7L valve covers will need to be modified to clear the stabilizers.

FAQ
What does the Texas Speed 5.7L Hemi rocker stabilizer kit do?
It braces the rocker shaft stands on a Gen III 5.7L Hemi with steel stabilizers and adds collars to the rocker shafts, keeping the shafts from moving under high spring pressure and rpm so the valvetrain stays stable.
What is included in the kit?
The kit includes ten high-grade steel rocker stabilizers and sixteen rocker shaft collars, enough for both cylinder heads on a 5.7L Hemi.
Which Hemi engines does this kit fit?
This kit is designed for the Gen III 5.7L Hemi. Texas Speed sells a separate rocker stabilizer kit, part number TSP-64HEMIVSK, for the Gen III 6.4L Hemi.
Do I need to modify anything to install the 5.7L stabilizers?
The stabilizers themselves bolt on, but Texas Speed notes the OEM 5.7L valve covers must be modified to clear them. No machining of the cylinder heads is required.
Who needs a rocker stabilizer kit?
Texas Speed recommends it for higher horsepower and higher rpm Hemi builds, such as cammed, supercharged or nitrous engines, where rocker stand movement can lead to valvetrain failure.
