Description

The Brian Tooley Racing Red Hot is one of the most talked about camshafts in the LS performance community right now — and this kit pairs it with a complete, matched valvetrain package built to support it at every RPM. 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, matched valvetrain package that leaves nothing to chance. 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 .619″/.617″ lift level — a serious spring package for a serious cam. Steel retainers and locks are included for a complete, professional spring installation with no additional parts needed. 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. Every component in this kit is selected to work together seamlessly so you can focus on the build — not the sourcing.

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.

This kit pairs the BTR Stage 3 Truck cam with a matched valvetrain package to support it from day one. The PAC1219-style beehive valve springs are purpose-matched to this cam’s .549″/.549″ lift profile, delivering the correct seat and open pressures for reliable high-RPM operation. Premium valve stem seals are included for a clean, oil-tight build, and the front timing cover gasket ensures your install is complete without any last-minute trips to the parts store. Every component in this kit is selected to work together seamlessly so you can focus on the build — not the sourcing.

• DYNO PROVEN +50HP +11TQ – MORE POWER WITH LESS DURATION – The BTR Red Hot delivers dyno-proven gains of 50+ rear wheel horsepower and 11+ lb-ft of torque while using less intake duration than BTR’s existing Stage 2 profiles. The result is a broader, more usable powerband that pulls strong in real-world driving conditions — not just on a dyno sheet. This is big power with street manners built right in.
• BTR RED HOT – ENGINEERED FOR N/A AND BOOSTED BUILDS – Most performance cams serve one application. The Red Hot serves two. The 113° LSA and .619″/.617″ lift profile were engineered to deliver exceptional power gains in both naturally aspirated and lightly boosted LS applications — making this one of the most versatile performance cam grinds in the BTR lineup and one of the fastest growing cams in the LS community.
• PRECISION-SPEC .660″ DUAL VALVE SPRINGS + STEEL RETAINERS + LOCKS – A serious spring package for a serious cam. The .660″ dual valve springs deliver the seat and open pressures needed for reliable high-RPM operation at the Red Hot’s lift level. Steel retainers and locks included for a complete professional spring installation — no additional parts needed. Premium valve stem seals included for a clean oil-tight build from day one.
• HARDENED CHROMOLY PUSHRODS – 7.400″ length, 0.080″ wall thickness. Built for the demands of a high-lift performance cam like the Red Hot. Stock pushrods flex under load — these don’t. A critical upgrade that serious LS builders never skip and one less thing to source separately.
