DYNOJET THUNDERSLIDE KIT `04-06 XL1200C/R - 133-4013

The Dynojet ThunderSlide Kit for the 2004-2006 Harley-Davidson XL1200C and XL1200R is a carburetor slide upgrade that replaces the stock slide with a custom-designed unit to deliver stronger throttle response and more usable power, making it the go-to Dynojet ThunderSlide Kit 2004-2006 XL1200C XL1200R carburetor upgrade for riders tired of a lazy, flat throttle. The Dynojet ThunderSlide Kit covers the full 2004 through 2006 XL1200C and XL1200R fitment window, so it's a proven fix across both Custom and Roadster variants of the iconic Sportster platform. Throttle feel gets noticeably crisp because the custom slide creates a stronger vacuum signal that pulls fuel into finer atomized droplets. At $222.21, it's a bench-install upgrade that wakes up your XL1200 without cracking open the engine.

• Fits 2004-2006 Harley-Davidson XL1200C and XL1200R carburetor applications across both Sportster variants.
