Brian Tooley BTR Stage 3 Truck Cam Kit 213/22X .549/.549 109 LSA + Trunnion Kit + Hardened Pushrods + PAC1219 Springs + Valve Seals – Fits 4.8L 5.3L 6.0L 6.2L LM7 LR4 LQ4 LQ9 – +63HP

Description

The Brian Tooley Racing BTR Stage 3 Truck cam delivers some of the strongest dyno-proven gains in the LS truck cam segment — delivering 63+ horsepower and 26+ lb-ft of torque with a broad 1,900–6,400 RPM operating range that means the power is usable everywhere and not just at peak RPM. Featuring 213/22X duration at .050″, .549″/.549″ valve lift, and 109 LSA, the Stage 3 sits at a 6 out of 10 on the chop scale — firing up with a confident aggressive chop that lets everyone know this truck has been properly built. BTR Stage 3 camshafts are designed in house, Spintron tested, and engine dyno proven before they ever reach a customer — born from their own specific cam core with no generic cores used — resulting in more average torque, higher peak power, and maximum depth heat treatment for long-term reliability. This complete kit includes everything a professional installer would spec — BTR Stage 3 Truck camshaft, PAC1219-style .625″ beehive valve springs, hardened chromoly pushrods at 7.400″ length and 0.080″ wall thickness, 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 PAC1219-style beehive springs are purpose-matched to the BTR Stage 3’s .549″/.549″ lift profile — delivering correct seat and open pressures for reliable high-RPM operation while keeping valvetrain mass low across all 4.8L, 5.3L, 6.0L, and 6.2L LS engine families. The hardened chromoly pushrods at 7.400″ length and 0.080″ wall thickness provide precise valve actuation and maximum strength under high performance conditions — stock pushrods flex under load on every LS cam swap and these don’t. 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. This is not a generic cam — it is a purpose-engineered performance grind built from its own specific cam core designed for maximum depth heat treatment and long-term reliability on every 4.8L, 5.3L, 6.0L, and 6.2L LS truck build. A 2,500–3,000 RPM stall converter is recommended for automatic applications. Brian Tooley Racing camshafts are designed and engineered in the USA — backed by extensive Spintron testing and in-house dyno development.

Compatible with 1999–2013 GM 4.8L, 5.3L, 6.0L, and 6.2L Vortec V8 engines including LR4, LM7, L59, LM4, L33, LQ4, LQ9, L76, L92, and L96. Fits Silverado 1500/2500/3500, Sierra 1500/2500/3500, Tahoe, Suburban, Yukon, Yukon XL, Escalade, Escalade ESV, Avalanche, Express Van, and Savana Van. Professional tune required for all applications. Fire it up and the BTR Stage 3 Truck cam fires up with a confident 6 out of 10 chop that lets everyone know this truck has been built — past converter stall the power comes on strong and stays strong all the way to 6,400 RPM. Big power. Broad powerband. Built for the street.

• 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.

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 hardened chromoly pushrods don’t.
