The Texas Speed Gen 4 LS2/LS3 Timing Cover Assembly is a complete front cover package engineered as a direct replacement for GM part number 12633906. It is built for Gen IV LS2 and LS3 engines that do not use variable valve timing, and it arrives with everything needed to seal the front of the engine and read cam position in one box.
The assembly includes the Texas Speed Gen 4 timing cover, a cam position sensor, the cam position sensor harness, a front crankshaft seal, a timing cover gasket and the cover bolts. Texas Speed specifies that the kit is intended for Gen 4 LS applications that are not running variable valve timing or factory dry sump oiling, so it suits wet sump LS2 and LS3 engines in cars and swaps rather than VVT or dry sump combinations.

FAQ
What GM part number does the Texas Speed LS2/LS3 timing cover assembly replace?
Texas Speed engineered this timing cover assembly as a direct replacement for GM part number 12633906, the Gen 4 front cover used on non-VVT LS2 and LS3 engines.
What is included with the Texas Speed Gen 4 timing cover kit?
The kit includes the Texas Speed Gen 4 timing cover, a cam position sensor, the cam position sensor harness, a front crankshaft seal, a timing cover gasket and the cover bolts, so no separate sensor or seal purchase is needed.
Does this timing cover work on engines with variable valve timing?
No. Texas Speed states the kit is for Gen 4 LS applications that are not running variable valve timing or factory dry sump oiling. Engines with a cam phaser or a factory dry sump system need a different cover.
Which engines is this timing cover assembly for?
It is designed for Gen IV LS2 and LS3 non-VVT applications, which in Texas Speed's fitment data covers the 2010 to 2015 Camaro, 2008 to 2013 Corvette and 2014 to 2017 Chevrolet SS with wet sump, non-VVT engines.
Is this the same cover used in the Texas Speed Gen 4 conversion package?
Yes. Texas Speed includes this LS2/LS3 timing cover assembly, part number TSP-3906, in its Gen 4 Engine Conversion Package for Gen 3 vehicles, where it supplies the front-mounted cam sensor the swap requires.
