The Texas Speed 4x Billet Upper Timing Gear is a Rollmaster-made billet upper camshaft sprocket with a 4x reluctor pattern for LS and LT engines that are not running variable valve timing. It replaces the factory upper timing gear in a non-VVT timing set, giving the cam sensor a 4x signal while using a billet gear in place of the stock stamped or cast piece.
Texas Speed sells this gear as part number TSP-10135. TSP's page does not list bolt pattern, tooth count or a specific timing set, so match the gear to the camshaft (1-bolt or 3-bolt) and the timing chain already in the engine before ordering, or ask Texas Speed or BPS to confirm compatibility with the build.

FAQ
What engines is the Texas Speed 4x billet upper timing gear for?
Texas Speed lists this Rollmaster billet upper gear for LS and LT engines that do not use variable valve timing, where a 4x cam signal sprocket is needed in the timing set.
Who makes the TSP-10135 upper gear?
The gear is made by Rollmaster and sold by Texas Speed under part number TSP-10135 as a billet upper timing gear with a 4x reluctor for non-VVT LS and LT engines.
Is the 4x upper gear compatible with a VVT camshaft?
No. Texas Speed specifies this gear for LS and LT engines without VVT. A factory VVT engine would need a phaser or a VVT delete setup rather than this gear alone.
Does the Texas Speed 4x billet upper gear come with bolts or a chain?
Texas Speed's listing covers the upper gear only. Cam bolts, the lower gear and the timing chain are not described as included, so plan on reusing or sourcing them separately.
