BTR LS Truck Cam Kit

BTR LS Truck Cam Kit combines a Brian Tooley Racing camshaft with a specified spring kit and chromoly pushrods for a Gen III/IV LS truck engine build or compatible engine swap. Select the camshaft for your engine combination and intended use.

Included with every camshaft choice

• One selected BTR camshaft: LS Truck Stage 1 V3, Stage 2 V3, Stage 3 V3, Stage 4 V3, Truck Norris, Truck Torque, Truck Hoss Stroker, or LS 400+ Low-Lift Truck.
• One set of 16 BTR chromoly one-piece pushrods: 7.400-inch length, 5/16-inch diameter, .080-inch wall. Verify required pushrod length and lifter preload during assembly; modified combinations may need a different length.
• All choices except Truck Hoss: one BTR-SK018 .625-inch-lift beehive valve spring kit with .045-inch-thick locators.
• Truck Hoss Stroker only: one BTR Platinum LS dual spring kit, SK001/S/0560/BB, with steel retainers, .660-inch lift capacity and .060-inch locators, in place of SK018.

BTR specifies that a separate seal selection is not required with SK018 or SK001. This package does not add a duplicate seal set.

Package choices and pricing

Stage 1–4 V3, Truck Norris and LS 400+ Low-Lift packages: $746.87. Truck Torque package: $727.47. Truck Hoss Stroker package: $824.47. Each price is for the components listed above, not a camshaft alone.

Application and installation

How to read the vehicle fitment list: Current vehicle references cover 1999–2013 Chevrolet Silverado 1500 and GMC Sierra 1500 with 4.8L/5.3L Gen III/IV LS V8 engines, plus 2007–2009 6.0L and 2009–2013 6.2L Silverado 1500/Sierra 1500 engine references, 1998–2002 Camaro SS/Z28 (LS1), 1997–2004 Corvette Base (LS1), and 2001–2004 Corvette Z06 (LS6). These are engine-family references for a performance build, not a promise that every camshaft choice suits the factory engine. They do not cover V6 models, Gen V direct-injected LT engines, diesel engines or older non-LS small-block engines. Other compatible LS swaps require build-specific confirmation; a swap vehicle is not automatically a stock bolt-on application.

Stroker-only choices: Truck Hoss and LS 400+ Low-Lift are intended for 400–416ci LS truck combinations with cathedral- or rectangular-port heads. Do not select either for an otherwise stock-displacement 4.8L, 5.3L, 5.7L, 6.0L or 6.2L engine simply because the vehicle appears in a fitment list. Vehicle references identify the engine family; the actual build and selected cam must be compatible.

For compatible Gen III/IV LS truck engine combinations and swaps using those engines. Fitment follows the installed engine and valvetrain, not simply the vehicle body. Camshaft selection, displacement, cylinder heads, piston-to-valve clearance, spring setup, pushrod length and calibration must be checked for the actual build.

BTR recommends SK018 for 6.0L/6.2L truck engines with square-port heads and for Stage 3/4 V3 truck cams. BTR requires the SK001 .660-inch spring kit with Truck Hoss; that kit is included in the Truck Hoss package here.

AFM/DOD, VVT and timing hardware: This is not a complete AFM/DOD or VVT conversion kit. Confirm whether the installed engine has either system before ordering. Engines retaining AFM/DOD hardware require an appropriate non-AFM valvetrain conversion for these performance cams; VVT-equipped engines require the appropriate non-VVT conversion and matching timing components. Confirm the selected cam's bolt pattern, cam/crank trigger compatibility and required calibration with the installer. Lifters, lifter trays, timing gears, conversion hardware, gaskets and tuning are not included unless expressly listed above. Hybrid powertrains require separate application review and are not represented as direct-fit installations by the 6.0L vehicle references.

Not included: pneumatic valve-holding tool, assembly lubricant, exhaust manifolds, installation labor, tuning or other installation components not expressly listed above. These are fixed-content SMGspeed packages assembled from BTR's available kit selections, not a reproduction of every optional add-on in BTR's configurator.

Provisional shipping weight: Stage 1–4 V3, Truck Norris, Truck Torque and LS 400+ Low-Lift combinations are estimated at 20 lb (camshaft 15 + SK018 springs 3 + pushrods 2). Truck Hoss is estimated at 25 lb (camshaft 15 + SK001 springs 8 + pushrods 2). These are sums of BTR catalog component weights, provisionally interpreted as pounds because the source omits units; they are not measured packed shipments. For shipping estimates, all eight package choices use a provisional 26 × 12 × 8-inch carton with a 1 lb empty-box/packing allowance, giving estimated packed weights of 21 lb for the SK018 combinations and 26 lb for Truck Hoss. These carton dimensions and the packing allowance are estimates, not manufacturer-confirmed measurements; verify the actual packed shipment before purchasing a label.

Compare LS truck options

BTR Truck Norris — camshaft only · BTR Truck Norris NSR — camshaft only · TSP LS Chopacabra — camshaft and spring package · BTR Weekend Warrior — camshaft kit

Compare like-for-like contents: Truck Norris and Truck Norris NSR links are camshaft-only listings; the TSP Chopacabra package includes its camshaft and PAC-2568 springs. NSR means no springs required for the cam's specified application; it does not make the cams interchangeable or eliminate application, clearance and calibration checks. The linked Chopacabra package is for cathedral-port 4.8L/5.3L LS truck engines, not Gen V LT or HEMI engines.

Manufacturer image is representative. The exact supplied components are the contents listed above for the selected camshaft.

SK018 hardware and rocker limits: The SK018 choices include springs, valve seals and locators, but reuse compatible factory retainers and locks; new retainers and locks are not included. Do not use OEM hat-style valve seals with SK018. BTR does not recommend these beehive springs with roller rockers or increased-ratio rockers without specific application review. Verify guide diameter, installed height, coil-bind clearance and retainer-to-seal clearance for the actual heads.
