BTR Brian Tooley RED HOT Cam Kit 221/24X .619/.617 113 LSA + LS7 Lifters + Trunnion Upgrade + .660″ Dual Springs + LS9 MLS Gaskets – Fits 6.0L 6.2L LQ4 LQ9 L76 L92 L96 LY6 – +50HP

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 6.0L and 6.2L 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, 16 premium LS7-style roller lifters with trays, .660″ dual valve spring kit with steel retainers and locks, hardened chromoly pushrods at 7.400″ length and 0.080″ wall thickness, premium valve stem seals, front timing cover gasket set, 2 LS9-style MLS head gaskets, and a premium LS rocker arm trunnion upgrade kit. One order, one shipment, zero guesswork. Lifetime warranty if installed by a certified machinist.

The 16 premium LS7-style roller lifters with trays reduce friction, improve oiling and stability at high RPM, maintain correct cam and lifter contact patterns for longer life, and simplify break-in for reliable valvetrain performance under load — the first upgrade every serious LS builder makes on any 6.0L LQ4 cam swap, 6.2L performance build, or rectangle port LS truck upgrade. The .660″ dual valve spring kit with steel retainers and locks delivers 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 with no additional parts needed. The LS9-style MLS head gaskets are precision matched to the larger bore rectangle port cylinder heads found on 6.0L and 6.2L LS engines — delivering superior crush resistance and long-term sealing reliability that composite gaskets simply cannot match. 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. 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 6.0L and 6.2L rectangle port Vortec V8 LS cam swap engines including LQ4, LQ9, L76, L92, L96, L9H, and LY6. Fits Silverado 1500HD/2500/2500HD/3500, Sierra 1500HD/2500/2500HD/3500, Tahoe, Suburban, Yukon, Yukon XL, Escalade, Escalade ESV, Avalanche, 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 6.0L or 6.2L 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.
