Description

If you want a complete, high-performance LS cam kit where every single part is proudly manufactured in the United States — this is it. The Brian Tooley Racing Stage 3 Truck cam is one of the most respected performance camshafts in the LS truck community, delivering 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 6.0L or 6.2L 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 supporting component in this kit is also made in the USA — and that matters. The genuine GM Performance 12499225 hydraulic roller lifters are manufactured right here in the United States — not generic offshore substitutes. These are the same trusted lifters used in OEM performance applications, chosen by professional engine builders who refuse to cut corners on the parts that keep a valvetrain alive under a performance cam. The head bolts are made by Elgin Industries or Fel-Pro — two of the most trusted American engine component manufacturers in the industry — delivering the clamping force your build demands for a proper, lasting seal. 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, providing superior crush resistance and long-term sealing reliability that composite gaskets simply cannot match. 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. A 2,500–3,000 RPM stall converter is recommended for automatic vehicles for best performance. Measuring piston-to-valve clearance prior to installation is always recommended. Every part in this kit is proudly made in the USA — because your build deserves nothing less. Big power. Broad powerband. Built for the street.
