The Texas Speed 1.7 Adjustable Shaft Mount Roller Rocker Package for 260cc Heads is a shaft-mounted valvetrain upgrade for LS engines running LS3-style or Texas Speed 260cc cylinder heads. The rockers are machined from 17-4 stainless steel with CHE bronze trunnions and swedged roller pins, and each design is Spintron tested in-house at Texas Speed to confirm stability at high rpm and with aggressive lobes.
The shaft mount design bolts to the factory rocker pedestals and ties the rockers together on a shaft for more stability than individual stud or pedestal rockers, which is why Texas Speed recommends this package for solid roller camshaft applications and high-performance builds. The 1.7 ratio is adjustable for lash and pushrod length setup. Texas Speed tall valve covers are required and minor trimming near the valve cover rail may be needed depending on the cylinder head casting.

FAQ
What cylinder heads does the Texas Speed 1.7 adjustable shaft mount rocker package for 260cc heads fit?
Texas Speed lists this package for LS3 and TSP 260cc cylinder heads, and its fitment notes also mention GM LS cathedral-port heads. It mounts on the factory rocker pedestals of those heads.
Do I need different valve covers with Texas Speed shaft mount rockers?
Yes. The shaft mount rockers sit taller than stock, so Texas Speed tall valve covers are required and minor trimming at the valve cover rail may be necessary depending on the head casting.
What is the difference between the 1.7 and 1.8 ratio Texas Speed 260cc rocker packages?
Both use the same 17-4 stainless shaft mount design with CHE bronze trunnions for LS3 and 260cc heads. The 1.8 ratio multiplies camshaft lobe lift more than the 1.7, giving more valve lift from the same cam, so the choice depends on the cam and spring package.
Are these rockers meant for hydraulic or solid roller camshafts?
Texas Speed recommends the adjustable shaft mount rockers for solid roller camshaft applications, where the adjustability sets valve lash and the shaft design keeps the valvetrain stable at high rpm.
What are the Texas Speed shaft mount rockers made from?
The rocker bodies are 17-4 stainless steel with CHE bronze trunnions and swedged roller pins, and the design is Spintron tested in-house by Texas Speed.
