March Performance Chevy Small Block "Ultra Drive" custom serpentine kits are designed for mounting accessories below the valve covers and in-between the width of the heads. These kits are a low-cost alternative to the Deluxe and Ultra Series that give up nothing in performance. Their components are precision CNC-machined from 6061-T6 aluminum for strength and perfect fit. The pulleys will not fracture like common cast pulleys, since they have high tensile strength for much longer wear—and are hard-coated for extra durability. Custom kits feature: * Sanden air conditioning compressor * 140 amp alternator * GMB aluminum reverse rotation water pump * Maval Type 2 power steering pump (except where noted) * Dayco spring loaded tensioner * Air conditioning bracket * Alternator bracket * Billet power steering bracket (except where noted) * Crank pulley * Hard-coated water pump pulley with fairing * Alternator pulley with machined fan * Power steering and tensioner pulleys * Wing cross emblem * Air conditioning line fittings * Grade 8 mounting hardware * Some models include power steering pump

An 883 to 1200cc Hooligan cylinder kit for a Harley-Davidson®, like the ones made by S&S Cycle, provides a significant increase in engine displacement, resulting in substantially more power and torque without requiring major engine modifications, making it a popular upgrade for riders seeking better performance on their Sportster 883, with benefits like increased horsepower—by boosting the engine size from 883cc to 1200cc, the Hooligan kit delivers a noticeable power gain, allowing for better acceleration and highway cruising capabilities. Typically these kits are designed as "bolt-on" upgrades, meaning they can be installed without needing extensive machining or engine rebalancing, making the process relatively simple and straightforward. Compared to a complete engine rebuild, a Hooligan kit is a cost-effective way to significantly improve your bike's power. When installing a Hooligan kit, it may be necessary to upgrade the clutch to handle the increased torque produced by the larger engine. Depending on the specific kit and your bike setup, you may need to adjust fuel injection mapping to optimize performance.
