Included in the selected configuration: One selected BTR camshaft and the exact SK001 spring kit selected below. A set of 16 BTR pushrods is included only when a pushrod length is selected; No pushrods includes none. Installation tools, lubricant, gaskets and other installation hardware are sold separately.
BTR LSA / PDS Cam Kit for GM Gen III/IV LS-based LSA and compatible positive-displacement-supercharged combinations.
Cam choices: PDS Stage 1 Torque, Stage 2 Torque, Stage 3 Torque V2, Stage 3 Torque for 1.8 rockers, Stage 4 V2, Stage 4 for 1.8 rockers, and LS Red Hot. Match the cam to the actual rocker ratio and engine build.
Spring-package reference: BTR Platinum .660-inch dual-spring packages are offered with steel or titanium retainers. Each retainer family has .045-inch and .060-inch locator versions for standard guides, .045-inch and .060-inch versions for bronze guides, and a .060-inch Dart/Edelbrock version. These are application-specific choices, not interchangeable upgrades; confirm the cylinder head and valve-guide configuration.
Optional pushrods: BTR 5/16-inch-diameter, .080-inch-wall chromoly pushrods, set of 16, in 7.350, 7.375, 7.400, 7.425 or 7.450-inch lengths. Measure required length for the assembled engine. Pushrods are not included when NONE is selected. Manufacturer listed 7.375-inch pushrods on backorder September 23, 2026; availability can change.
Package pricing reference: Manufacturer-configured cam and steel-retainer spring packages were $708.08 without pushrods or $824.47 with a pushrod set; titanium-retainer packages were $756.58 or $872.97 respectively, verified September 23, 2026. Optional installation tools are separate, not included in these totals. Driven assembly lubricant is not a BTR-branded component and is not included.
Fitment: GM Gen III/IV LS-based LSA and compatible positive-displacement-supercharged combinations; not a Gen V LT cam kit. Final fitment depends on the selected cam, cylinder head, rocker ratio, measured pushrod length, spring package, induction, and boost configuration. An engine swap requires checking the installed engine and valvetrain rather than relying on the vehicle name alone.
Inventory & shipping: Manual BTR listing; inventory is not tracked and keep-selling is enabled. Estimated shipping setup: 26 × 12 × 8-inch carton with 1 lb separate tare; contents allowance is 25 lb without pushrods or 28 lb with pushrods. These conservative allowances include packing and are not measured weights for each combination. Verify the actual packed shipment before purchasing a label.
Native LSA vehicle applications: 2012–2015 Chevrolet Camaro ZL1 and LSA-equipped 2009–2015 Cadillac CTS-V; 2015 CTS-V coverage is the coupe only. This is not blanket fitment for Camaro LS/LT/SS trims, Cadillac V-Sport, 2016+ LT4 CTS-V, or every Corvette. Engine swaps and modified heads require checking the installed engine, guides, retainers, rocker ratio and clearances. LS9/Corvette ZR1 use requires separate verification of the complete spring/valvetrain package.
Optional BTR installation tools, sold separately: BTR-T001 pneumatic valve-holding tool, T002 valve-seal installer, and BTRHM spring-height micrometer. Check each tool’s dimensions and application requirements before ordering.
