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 is the most complete version of it you will find anywhere. BTR's Stage 3 Truck grind sits in the sweet spot of the truck cam lineup: aggressive enough to deliver dyno- proven gains of 63+ horsepower and 26+ lb-ft of torque, while still being manageable enough for a street-driven build with the right supporting mods and a proper tune. With a 1,900–6,400 RPM operating range, a 6/10 chop rating, and .549"/.549" valve lift, this cam delivers a broad, usable powerband that pulls strong from the bottom all the way to redline. Fire it up and the Stage 3 announces itself immediately — confident, lopey, and impossible to mistake for stock. This kit is built around a complete, precision-matched valvetrain that leaves nothing to chance. The 16 premium LS7-style roller lifters with trays are wider, more stable, and purpose-built for high-lift aggressive cam profiles — the first upgrade every serious LS builder makes. The .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. Premium valve stem seals and a front timing cover gasket round out the install so nothing gets left out. The two included LS1-style Multi-Layer Steel head gaskets are precision matched to the cathedral port cylinder heads found on 5.7L, 4.8L, and 5.3L LS engines — the gold standard for sealing a performance build under sustained high cylinder pressure. This kit is compatible with 1999–2013 GM 5.7L, 4.8L, and 5.3L Vortec LS engines. A professional tune is required. A 2,500–3,000 RPM stall converter is recommended for automatic vehicles. Measuring piston-to-valve clearance prior to installation is always recommended. Big power. Broad powerband. Built for the street.
