The Texas Speed Stock LM7-Style 3-Bolt Camshaft is a factory-profile replacement camshaft for the 1999 to 2006 5.3L LM7 found in GM trucks and SUVs. It carries the stock 190/191 duration, .466"/.457" lift, 114 LSA grind on a three-bolt core, so it drops in with all of the factory valvetrain hardware and, per Texas Speed, does not require any additional tuning.
Texas Speed positions this cam as the right choice for a stock or daily-driven truck that needs a replacement camshaft, including after a DOD delete, where the goal is factory manners rather than added power. It is rated daily driver friendly with a smooth, near-stock idle and no valve spring upgrade is needed.

FAQ
What engines does the Texas Speed 315267 camshaft fit?
Texas Speed lists it as a factory-style camshaft for the 1999 to 2006 5.3L LM7, the three-bolt Gen III 5.3L used in Silverado, Sierra, Tahoe, Suburban and Yukon trucks and SUVs of those years.
Is the stock LM7-style cam a single-bolt or three-bolt camshaft?
It is a three-bolt camshaft. Texas Speed sells the single-bolt 315215 for Gen IV 5.3L engines that use the single-bolt cam gear.
Do I need a tune or new springs with this camshaft?
No. Texas Speed states the cam is compatible with all factory hardware and does not require additional tuning, and no valve spring upgrade is required since it is a stock 190/191 profile.
Why would I replace an LM7 cam with a stock-profile camshaft?
Texas Speed describes it as the choice for stock or daily-driver trucks that need a replacement camshaft, including after a DOD delete, when the owner wants factory idle and drivability instead of a performance cam.
Does this camshaft add horsepower?
No. It duplicates the factory 190/191 duration, .466"/.457" lift grind with a smooth, near-stock idle. Texas Speed offers its low lift and stage truck cams for added power.
