Brian Tooley BTR Red Hot Cam Kit 221/24X .619/.617 113 LSA + Trunnion Kit + .625 Beehive Springs + Valve Seals – Fits 4.8L 5.3L 6.0L 6.2L LM7 LR4 L59 LQ4 LQ9 L76 – +50HP – N/A & Boosted

Description

The Brian Tooley Racing BTR Red Hot is one of the fastest growing cams in the LS community — delivering 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. Featuring 221/24X duration at .050″, .619″/.617″ asymmetric valve lift, and 113 LSA, the Red Hot delivers a broader more usable powerband that pulls strong in real-world driving conditions — not just on a dyno sheet. 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 entire BTR lineup. This complete kit includes everything a professional installer would spec — BTR Red Hot camshaft, .625″ beehive valve springs, premium valve stem seals, front timing cover gasket set, and a premium LS rocker arm trunnion upgrade kit. One order, one shipment, zero guesswork. Lifetime warranty if installed by a certified machinist.

The .625″ beehive springs are purpose-matched to the Red Hot’s .619″/.617″ asymmetric lift profile for correct spring pressure and reliable high-RPM operation — lighter than a dual spring setup these beehive springs reduce valvetrain mass while delivering the control this cam demands at high RPM. The premium LS rocker arm trunnion upgrade kit converts your stock LS rocker arms into captured roller bearing rocker arms — eliminating the factory failure point that has caused catastrophic engine damage in countless LS builds. A 2,800–3,200 RPM stall converter is recommended for automatic applications. Whether you are building a naturally aspirated 5.3L cam swap, a 6.0L LQ4 truck upgrade, a lightly boosted 4.8L build, or a turbocharged 6.2L LS performance build — the BTR Red Hot delivers exceptional power gains across the entire RPM range. Brian Tooley Racing camshafts are designed and manufactured in the USA — backed by extensive in-house dyno development and real world engine testing.

Compatible with 1999–2013 GM 4.8L, 5.3L, 6.0L, and 6.2L Vortec V8 engines including LR4, LM7, L59, LM4, L33, LH6, LC9, LY5, LMG, LQ4, LQ9, L76, L92, and L96. Fits Silverado, Sierra, Tahoe, Suburban, Yukon, Yukon XL, Escalade, Avalanche, TrailBlazer SS, Pontiac GTO, Pontiac G8, Express Van, and Savana Van. A 2,800–3,200 RPM stall converter is recommended for automatic applications. Professional tune required for all applications. Fire it up and the Red Hot delivers a confident aggressive idle that lets everyone nearby know this LS has been properly built — past converter stall the throttle response is sharp, the power is broad and strong, and the pull stays relentless all the way through the RPM range. Big power. Broad powerband. Built for the street.

• BTR RED HOT – ENGINEERED FOR N/A AND BOOSTED BUILDS – Most performance cams serve one application — the BTR Red Hot serves two. The 113 LSA and .619″/.617″ asymmetric 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 entire BTR lineup. One of the fastest growing cams in the LS community for 4.8L 5.3L 6.0L and 6.2L builds running N/A or boost.
• PREMIUM LS ROCKER ARM TRUNNION UPGRADE KIT – DO NOT SKIP THIS ON YOUR LS BUILD – The factory LS rocker arm trunnion is a known failure point across the entire LS engine family. When the factory pressed-in needle bearings fail they send small bearings through the entire engine causing catastrophic damage to your 4.8L 5.3L 6.0L or 6.2L LS build. This retrofit trunnion kit converts stock LS rocker arms into captured roller bearing rocker arms — eliminating the factory failure point entirely. Trusted in everything from stock 4.8L daily drivers to 1,000+ horsepower turbo motors.
• MATCHED .625″ BEEHIVE SPRINGS + VALVE STEM SEALS – Purpose-matched to the Red Hot’s .619″/.617″ asymmetric lift profile for correct spring pressure and reliable high-RPM operation across all 4.8L 5.3L 6.0L and 6.2L LS engine families. Lighter than a dual spring setup these beehive springs reduce valvetrain mass while delivering the control this cam demands at high RPM. Compatible with beehive spring setups — no dual spring kit required. Premium valve stem seals included for a clean oil-tight build from day one.
