Description

The Brian Tooley Racing Stage 3 Truck cam is one of the most respected performance camshafts in the LS truck community — and this kit gives you everything needed to install it right the first time on your 2007+ 6.0L or 6.2L rectangle port engine. BTR's Stage 3 Truck grind delivers dyno-proven gains of 63+ horsepower and 26+ lb-ft of torque with a broad 1,900–6,400 RPM operating range and a 6/10 chop that gives your truck the sound and attitude it deserves. BTR designs, tests, and manufactures their camshafts right here in the USA — Spintron tested and engine dyno proven before they ever reach a customer. This is not a generic cam — it is a purpose-engineered performance grind built to last. Every component in this kit was chosen because it belongs in a professional build. The genuine GM Performance 12499225 hydraulic roller lifters are manufactured right here in the United States — not generic offshore substitutes. The PAC1219-style .625" beehive valve springs with steel retainers 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. Steel retainers lock everything down securely under sustained load. 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 deliver the clamping force your build demands, backed by decades of proven American manufacturing. The full upper MLS head gasket set is precision matched to the rectangle port cylinder heads found on 2007+ 6.0L and 6.2L LS engines — the gold standard for sealing a performance build under sustained high cylinder pressure, proudly made in the USA. This kit is built specifically for 2007–2013 GM 6.0L and 6.2L rectangle port Vortec LS engines. A professional tune is required. A 2,500–3,000 RPM stall converter is recommended for automatic vehicles. Big power. Broad powerband. Built for the street.
