Brian Tooley BTR Stage 2 Truck Cam Kit 208/21X .549/.549 108.5 LSA + Trunnion Kit + PAC1219 Beehive Springs + Valve Seals – Fits 4.8L 5.3L 6.0L 6.2L LM7 LR4 L59 LQ4 LQ9 L76 – +52HP

Description

The Brian Tooley Racing BTR Stage 2 Truck cam delivers dyno-proven gains of 52+ horsepower and 24+ lb-ft of torque across a broad 1,300–6,250 RPM operating range — the ideal cam for a daily driven LS truck that wants to sound and perform noticeably better than stock. Featuring 208/21X duration at .050″, .549″/.549″ valve lift, and 108.5 LSA, the Stage 2 works with stock torque converters and maintains excellent street manners — delivering a confident throaty cam note at startup that separates it from every stock truck on the road without the rough idle that makes a daily driver miserable. BTR camshafts are designed in house, Spintron tested, and engine dyno proven before they ever reach a customer — each cam born from its 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 2 Truck camshaft, PAC1219-style .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 PAC1219-style .625″ beehive springs are purpose-matched to the Stage 2’s .549″/.549″ lift profile — delivering correct spring pressure and reliable high-RPM operation while keeping valvetrain mass low 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 throughout the entire 1,300–6,250 RPM power band. 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. Pull onto the highway and the broad powerband delivers strong confident acceleration from 1,300 all the way to 6,250 RPM — throttle response is sharper, highway pulls are noticeably stronger, and the power is always right there when you need it. 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, LH6, LC9, LY5, LMG, LQ4, LQ9, L76, L92, and L96. Fits Silverado, Sierra, Tahoe, Suburban, Yukon, Yukon XL, Escalade, Avalanche, Express Van, and Savana Van. Works with stock torque converters — no stall upgrade needed. Fire it up and the BTR Stage 2 delivers a confident throaty cam note that separates it from every stock truck on the road — a refined daily driver upgrade that makes your 4.8L 5.3L 6.0L or 6.2L LS truck feel alive every single time you drive it. 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.

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.
