March Performance small block Chevy Ultra serpentine conversion kits will make it easy to convert your old V-belt pulleys. They bolt to the front of any 1969 or later small block Chevy heads and are precision CNC-machined from solid billet 6061 T-6 aluminum to fit perfectly and handle high-torque and vibration. The included bracket kits come complete with stainless steel tensioning rods and chromoly rod ends for high performance operation. Required mounting hardware is included and is powdercoated to eliminate polishing in those hard-to-reach places. Matching serpentine pulleys are precision CNC-machined from 6061 T-6 aluminum. These pulleys will not fracture like common cast pulleys because they are hard coated in the high-wear areas on their high water flow ratio pulleys. The street rod ratio increases water flow and fan speed. This helps at critical low-speed driving.

The primary purpose of S&S Cycle's 750cc big bore kits is to enhance the performance of smaller engine models, particularly for the Street 500 or Street 750, giving them more power and acceleration. These stock bore cylinder kits are designed to increase the engine displacement by enlarging the cylinder bore, resulting in more power and torque compared to the stock engine, typically by converting a smaller displacement engine like a 500cc or 650cc into a 750cc unit. Many big bore kits are designed to be "bolt-on" upgrades, meaning they can be installed without requiring extensive engine modifications or machining, making them relatively easy to add to a motorcycle. Before ordering, make sure this kit is compatible with your specific street bike model.

COMP Cams Nitrous HP cam and lifter kits are designed to work with your nitrous system to get more power from your engine. The unique intake cam lobes allow your engine cylinders to fill better for more complete combustion. While, the exhaust lobes are spread to decrease overlap and ensure maximum scavenging of your combustion chamber. The bottom line is an increased power boost from your nitrous system, without any loss of throttle response or torque in street applications.

Eagle forged 4340 steel crankshafts are great for high performance applications. They feature non-twist forging, undergo a multi-stage heat-treatment process, and are stress-relieved and shot-peened. These cranks are X-rayed, magnafluxed, and sonic-tested, so you know you're getting a top-quality piece. Each crankshaft has chamfered oil holes for improved oiling, a .125 in. radius on rod and main journals for increased strength, and the journals are precision-ground and micro-polished to less than 5 R.A. A target bob weight of +/- 2 percent greatly reduces balancing time. Many options are available; order the model recommended for your year/make and engine application.
