Our new AFR camshafts are the ultimate compliment to your LS powered cehicle. Whether you have a stock Silverado or Sierra pickup, or GEN V Camaro or a C6 Corvette with some AFR heads on it, we can take your setup from mild to wild with one of three new bump sticks.

All AFR Camshafts are made using a billet steel core and are suitable for factory displacement engines ranging from 5.7 to 6.2. Installation will require the use of a 3-bolt style cam gear and bolts, AFR part #6010 (gear) and AFR part #6011 (3 bolts).

AFR camshafts makes more power and torque everywhere in the curve. Develped in house, we went to the drawing board and found more power and torque even with the use of less intake duration. These AFR camshafts have been Dyno tested to achieve the highest overall power curve while also maintaining strict valvetrain stability and durability standards.
