Trick Flow has introduced a new top end kit specifically for GM trucks sporting the 5.3-liter LS engine. Since there are hundreds of thousands, perhaps millions of these trucks on the road today, it is a brilliant idea. The kit includes heads, a cam, Harland Sharp roller rockers, head gaskets, push rods, and bolts. This kit is the biggest no brainer in the history of hot rodding LS engines. 

Trick Flow says that bolting on the Gen-X top end kit is worth 50-70 horse power at the rear wheels! That’s plenty to turn your normally zippy truck into a tire shredder with upwards of 450hp and 425 ft/lbs of torque. That’ll make your trailer towing duties easier, and your ability to hit a test and tune night with the intention of eating “hot” cars alive a complete guarantee.

Why bother considering a total engine swap for a 6.0L engine when this kit can get the job done and a whole lot more, for a whole lot less money? Blame Trick Flow the next time a stock looking truck walks your muscle car.

Here’s the full release from Trick Flow :

AKRON, OH—
Trick
Flow has taken its proven formula for creating complete top-end kits for GM LS
engines—the same formula that helped make up to 515 horsepower on a stock GM
5.7L LS1 short block—and developed a potent top-end kit for GM 5.3L LS-powered
trucks. When tested on a GMPP LS327 short block, this new Trick Flow GenX^® Top-End Engine
Kit for GM LS Trucks made 455 horsepower and 425 ft.-lbs. of torque.

            The
Trick Flow GenX Top-End Engine Kit for GM LS Trucks takes the guesswork out of
buying top-end components by bringing together performance-matched components
in one complete, power-building package. It includes a pair of GenX 205 cylinder
heads (TFS-30500001-C00), a hydraulic roller camshaft (TFS-30602001), heat-treated
chromemoly pushrods (TFS-21407500), Harland Sharp roller rocker arms, and GM
Performance Parts head and exhaust gaskets and bolts—everything needed to add
50-70 horsepower at the rear wheels.
