The Texas Speed Steel LT1 1.82 Ratio Roller Rocker Package replaces the factory rocker arms on the Gen V 6.2L LT1 with steel rockers that offer more strength than the stock setup. A roller tip reduces wear and friction at the valve tip, and the design avoids the added valvetrain weight found on some heavier aftermarket rockers.
The rockers come standard with the TSP trunnion upgrade kit installed, which replaces the factory trunnion with quality bearings for long service life, and Texas Speed offers a second trunnion option selected at ordering. The 1.82 ratio increases valve lift and effective duration over the factory ratio for a given camshaft, so spring travel and piston-to-valve clearance should be confirmed with the camshaft in use.

FAQ
What engines do the Texas Speed LT1 1.82 steel rocker arms fit?
Texas Speed lists this steel roller rocker package for the Gen V 6.2L LT1, as found in the 2014 to 2019 Corvette and 2016 to 2024 Camaro SS shown in the vehicle list.
Is the trunnion upgrade included?
Yes. The rockers come standard with the TSP trunnion upgrade kit installed, which uses quality bearings for long life. A COMP trunnion version is offered as the alternate option at ordering.
What does the 1.82 ratio change compared with the factory LT1 rocker?
A higher rocker ratio multiplies camshaft lobe lift by a larger factor, so valve lift and effective duration increase with the same camshaft. Spring travel and piston-to-valve clearance should be checked with the camshaft being used.
Why choose a steel roller tip rocker over the stock LT1 rocker?
Texas Speed states the steel rockers are stronger than the factory setup and the roller tip reduces wear and friction on the valve tip, while keeping valvetrain weight lower than some other aftermarket rockers on the market.
Are these LT1 rockers adjustable?
No. This is a fixed pedestal-mount rocker package for hydraulic roller LT1 valvetrains. Texas Speed sells separate adjustable rocker packages for solid roller applications.
