Description

The Brian Tooley Racing BTR Stage 4 V3 is the most aggressive option in BTR’s revamped LS truck cam lineup — delivering dyno-proven gains of 72+ horsepower, 24+ lb-ft of torque, and an extra 1,000+ RPM of usable power over stock on a stock Gen IV 5.3L with stock heads. Featuring 219/23X duration at .050″, .553″/.553″ valve lift, 108.5 LSA, and a broad 2,200–6,700 RPM operating range, the Stage 4 V3 sits at an 8 out of 10 on the chop scale — delivering a very aggressive lopey idle that announces this LS truck means serious business. A 2,800+ RPM stall converter is recommended for 6.0L and 6.2L automatic applications. This complete kit includes everything a professional installer would spec — BTR Stage 4 V3 camshaft, 16 premium LS7-style roller lifters with trays, Redline 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, 2 LS9-style MLS head gaskets, and a premium LS rocker arm trunnion upgrade kit. No piecing parts together from multiple sellers. 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 Redline PAC1219-style .625″ beehive springs are purpose-matched to the Stage 4 V3’s .553″/.553″ lift profile — delivering a max lift of .625″, spring rate of 340 lbs/in, coil bind at 1.100″, installed height of 1.800″ at 135 lbs, and open load of 348 lbs at 1.175″ for correct spring pressure and reliable high-RPM operation. 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 engineered 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.
