Brian Tooley BTR Stage 2 Truck Camshaft Install Kit w/ GM 12499225 Lifters, Beehive Springs, Retainers, Push Rods, Gaskets | 208/21X .549/.549 108.5 LSA | Fits GM 6.0 6.2 Rectangle Port – MADE IN USA

Description

The Brian Tooley Racing Stage 2 Truck cam is the perfect upgrade for the driver who wants their daily driven 2007+ 6.0L or 6.2L rectangle port engine to sound and feel noticeably different from stock — without sacrificing the drivability that makes it livable every single day. With a broad 1,300–6,250 RPM operating range, dyno-proven gains of 52+ horsepower and 24+ lb-ft of torque, and a cam note that lets everyone nearby know this truck has been built, the Stage 2 hits the sweet spot between mild and aggressive that most daily driver builds are looking for. The .549″/.549″ valve lift and 108.5° LSA deliver a powerband that starts pulling early and stays strong well past highway speeds — exactly what a truck that does double duty as a weekend performer needs.

This kit is built around a complete, matched valvetrain package that leaves nothing to chance. The genuine GM Performance 12499225 hydraulic roller lifters are manufactured right here in the United States — not generic offshore substitutes. The .625″ beehive valve springs with steel retainers and locks are purpose-matched to this cam’s .549″/.549″ lift profile, delivering correct spring pressure and reliable high-RPM operation while keeping valvetrain mass low. Hardened chromoly pushrods at 7.400″ length and 0.080″ wall thickness eliminate the flex that stock pushrods cannot handle under a performance cam — a critical upgrade that serious LS builders never skip. The USA-made Elgin or Fel-Pro head bolts and premium upper MLS head gasket set round out the kit, precision matched to the rectangle port cylinder heads found on 2007+ 6.0L and 6.2L LS engines.

This kit is built specifically for 2007–2013 GM 6.0L and 6.2L rectangle port Vortec LS engines. A professional tune is required for both automatic and manual applications. This cam works well with stock torque converters making it an ideal daily driver upgrade. Measuring piston-to-valve clearance prior to installation is always recommended. Big power. Broad powerband. Built for the street.
