BTR LVX V6 Cam, Springs and Phaser Hardware Kit

Build a BTR Gen V V6 cam package with a specified camshaft, matched springs and your selected VVT hardware. This SMGspeed selection is based on BTR’s LVX kit configurator; it is not a complete DOD/AFM-delete or installation kit.

Included components

• Truck Norris Jr: BTR-TRUCKNORRISJR cam plus BTR91120-12 beehive spring set and the selected limiter.
• LVX Stage 2: BTR-LVXSTAGE2 cam plus BTR91120-12 beehive spring set and the selected limiter.
• V6 Turbo: BTR-LVTURBO cam plus SK007/0560/BB/V6 dual-spring kit and the selected full lockout. Limiter-only combinations are not offered for Turbo.

Select the correct phaser hardware

Match Gen V versus Gen V Plus to the phaser actually installed in your engine. Choose limiter travel only after checking the current cam card, clearances and calibration with your engine builder. Vehicle year alone does not determine the correct hardware. Do not substitute a limiter for the Turbo cam’s required full lockout.

• Gen V - 8-degree limiter: BTR-VVT-GENV-8CAM
• Gen V - 4-degree limiter: BTR-VVT-GENV-4CAM
• Gen V Plus - 8-degree limiter: BTR-VVT-GEN-VP-8CAM
• Gen V Plus - 4-degree limiter: BTR-VVT-GEN-VP-4CAM
• Gen V - full lockout: BTR-VVT-GENV-LO
• Gen V Plus - full lockout: BTR-VVT-GEN-VP-LO

Native engine applications and swaps

Engine-qualified applications: 2014–2021 Chevrolet Silverado 1500 and GMC Sierra 1500 equipped with the 4.3L LV3 Gen V V6. These are engine-family references for a modified performance build, not a stock replacement or no-modification fitment guarantee. Confirm the engine RPO before ordering. Excludes V8 trucks, diesel engines, the 2.7L turbo four-cylinder and earlier-generation 4.3L Vortec V6 engines. Other LV versions and swapped vehicles require individual compatibility verification.

Not included

Optional lifters and a separate valve-seal set from BTR’s configurator are not added to these packages. Pushrods, gaskets, DOD/AFM-delete hardware, tools, tuning and installation labor are not included. Jr and Stage 2 use stock retainers and locks with the BTR91120-12 spring set; replacement retainers, locks and valve seals are not included with those spring sets. The Turbo option’s SK007/0560/BB/V6 kit includes 12 springs, 12 titanium retainers, 12 stock-guide locators, 12 seals, 24 locks and 12 shims. It is designed for stock rocker arms. Verify installed height, clearances and valvetrain compatibility before assembly.

Availability: The Turbo cam and Gen V Plus 4-degree limiter were shown on backorder at BTR on September 22, 2026. Confirm lead times before scheduling installation.

Shipping: Estimated components/packing allowance: 26 lb, using BTR’s catalog entries of 15 for the cam and 10 for either spring set, interpreted as pounds, plus a provisional 1 lb hardware/packing allowance. Provisional shipping carton: 26 × 12 × 8 inches with an additional 1 lb carton weight (27 lb estimated packed total). These are estimates, not measured packed specifications.
