COMPLETE BTR RED HOT CAM KIT – Brian Tooley Racing BTR Red Hot Camshaft (221/24X, .619"/.617", 113 LSA, 3-Bolt, Made in USA), 16 Premium LS7-Style Roller Lifters, 7102-Style Billet Steel Double Roller Timing Set, .660" Dual Valve Springs with Steel Retainers and Locks, Hardened Chromoly Pushrods (7.400", 0.080" wall), Premium Valve Stem Seals, and a Premium LS Rocker Arm Trunnion Upgrade Kit. Most complete BTR Red Hot cam kit for 4.8L 5.3L 6.0L and 6.2L LS cam swaps — one order one shipment zero guesswork.
DYNO PROVEN +50HP +11TQ – MORE POWER WITH LESS DURATION – 221/24X Duration at .050", .619"/.617" Asymmetric Valve Lift, 113 LSA, 3-Bolt Pattern. 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.
16 PREMIUM LS7 LIFTERS + 7102 BILLET DOUBLE ROLLER TIMING SET – LS7-style lifters are wider more stable and built to handle the aggressive high lift cam profile of the BTR Red Hot without failure — the first upgrade every serious LS builder makes on any 4.8L or 5.3L cam swap, 6.0L LQ4 truck upgrade, or 6.2L LS performance build. The 7102-style billet steel double roller timing set delivers rock-solid cam timing accuracy and long-term durability that stock timing chains simply cannot match. This is the hardware that separates a proper BTR Red Hot LS cam swap from a basic parts swap.
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.
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.
PRECISION-SPEC .660" DUAL VALVE SPRINGS + STEEL RETAINERS + LOCKS + HARDENED PUSHRODS – 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 .619"/.617" lift level. Steel retainers and locks included for a complete professional spring installation — no additional parts needed. Hardened chromoly pushrods at 7.400" length and 0.080" wall thickness eliminate flex under load — stock pushrods flex on every LS cam swap these don't.
