The Texas Speed Steel Adjustable LS7 1.82 Roller Rocker Package is an adjustable version of the Texas Speed LS7 roller rocker arm, built for solid roller camshaft applications on the 7.0L LS7. The steel body rockers bolt into the existing LS7 rocker mounts, so they install as a direct bolt-in without extra cylinder head milling while giving the builder a fully adjustable rocker for setting lash.
Each rocker includes the adjustment cup and nut, and the package is offered with the TSP trunnion upgrade or with the alternate trunnion option selected at ordering. Like all adjustable rockers, these require taller valve covers or valve cover spacers, and some hand clearancing of the cylinder head casting may be needed depending on core shift in the castings.

FAQ
What engine does the Texas Speed adjustable LS7 1.82 rocker package fit?
It is designed for the 7.0L LS7 and bolts into the existing LS7 rocker mounts, which covers the 2006 to 2013 Corvette Z06 and the 2014 to 2015 Camaro Z/28 listed by Texas Speed.
Do these rockers require cylinder head machining?
No milling is required. Texas Speed designed the package as a direct bolt-in to the factory LS7 rocker mounts, though hand clearancing of the head casting may be needed depending on core shift.
Will the factory LS7 valve covers fit over the adjustable rockers?
No. Like all adjustable rocker systems, this package requires taller valve covers or valve cover spacers to clear the adjusters.
What is the difference between the two trunnion options?
Texas Speed offers the package with its own TSP trunnion upgrade kit (TSP-182RR-ADJ-LS7) or in a COMP version (TSP-182RR-COMP-ADJ-LS7), selected under the Bearings or Bushings option. The rocker body, 1.82 ratio and adjuster are the same in both.
Are these rockers for hydraulic or solid roller camshafts?
Texas Speed built the adjustable LS7 rocker package for solid roller applications, where the adjustment cup and nut allow valve lash to be set on each rocker.
