The Low Buck Truck cam is the most popular cam we offer. It offers gains of 60+ hp over the stock 4.8L or 5.3L stock cams. The Low Buck Truck cam is perfect for daily driver and works with a stock converter, but a higher stall will improve performance. This cam requires .550-lift springs and can be run with stock LS3/LS6 springs or aftermarket 550-lift springs (avail soon). The cam requires a tune. This Low Buck Truck cam has been extensively dyno tested and has been run successfully NA, with every type of blower (centrifugal, roots and twin screw) and with a Turbo. It works very well under boost.

The Low Buck Truck also makes an amazing TURBO cam. The low-speed torque offered by the Low Buck Truck makes for awesome boost response, and you can easily exceed 1000 hp with a Low Buck Truck with the right turbo (coming soon). On this test, we ran a junkyard L33 5.3L with the Low Buck Truck cam and springs package, then added a single S475 Borg turbo. The NA motor made 422 hp (adding 60+ hp over stock), then made 620+ hp at 7.5 psi, then 920+ hp at 17 psi. This cam (like most) works very well with boost!

BTR's .560" lift LS6-style valve springs gives you all of the performance of the venerable OEM LS6 valve spring (GM part # 12499224 or 12586484) at a fraction of the cost.
