This comprehensive package includes CNC-ported cylinder heads with performance valve springs, Screamin' Eagle® XL SE-585 cams, forged hi-compression 10.5:1 pistons and rings, a 58mm throttle body with intake manifold, and a complete top-end gasket kit. This kit aims to maximize horsepower and torque without requiring the powertrain to be removed from the chassis. It allows you to build a high-performance motorcycle while maintaining your original factory warranty. The components are finished in black. Installation of this kit requires a dealer-installed ECM calibration download or the use of the tunable Screamin' Eagle Street Tuner Kit, which is sold separately. Additionally, an accessory 58mm air cleaner must be purchased separately. The kit is confirmed to fit all EFI-equipped '14-later XL1200 models. Model year '16 is pending 50-state certification approval.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
