Description

The Brian Tooley Racing Red Hot is one of the most talked about camshafts in the LS performance community right now — and this is the most complete kit you will find anywhere to install it. The Red Hot was engineered to deliver more power than BTR’s existing Stage 2 profiles while using less intake duration, resulting in a broader, more usable powerband that works equally well in naturally aspirated and lightly boosted applications. With dyno-proven gains of 50+ rear wheel horsepower and 11+ lb-ft of torque, a 113° LSA that keeps the powerband broad and accessible, and .619″/.617″ valve lift, the Red Hot is the cam for builders who want serious real-world performance without sacrificing street manners. Fire it up and you will know immediately this isn’t a stock LS anymore.
This kit is built around a complete, precision-matched valvetrain package that leaves nothing to chance. The 16 premium LS7-style roller lifters are wider, more stable, and purpose-built to survive the demands of a high-lift aggressive cam profile where standard lifters fail. The 7102-style billet steel double roller timing set delivers rock-solid cam timing accuracy and long-term durability that stock timing chains cannot match — a mandatory upgrade for any serious performance cam install. The .660″ dual valve springs with steel retainers and locks deliver the seat and open pressures needed for reliable high-RPM operation at the Red Hot’s lift level. The hardened chromoly pushrods at 7.400″ length and 0.080″ wall thickness eliminate the flex that stock pushrods cannot handle under a performance cam, and premium valve stem seals ensure a clean, oil-tight build from day one.
This kit is compatible with 1999–2013 GM 4.8L, 5.3L, 6.0L, and 6.2L Vortec LS engines across both cathedral port and rectangle port cylinder head families. A professional tune is required for both automatic and manual applications. A 2,800–3,200 RPM stall converter is recommended for automatic vehicles for best performance. Measuring piston-to-valve clearance prior to installation is always recommended. Big power. Broad powerband. Built for the street.
