Burly combined their dropped fork springs and stubby shocks into a very price friendly package. The front fork spring kit is a drop-in design. These do not require the disassembly of the fork and can be installed in twenty minutes in Dyna's and Sportsters with the forks still on the bike. The rear shocks are all-black 10 1/2" (26.7 cm) and come with the chrome springs and chrome top cover installed, ready to bolt on your bike. Kits for 2004 to present XL Sportster are also available with black springs and covers. In fact, the entire Slammer kit is set up to go from box to bike in under an hour on most models with just basic tools. Step-by-step installation instructions are included. Dependent on the application, kits lower the front up to 2" (5 cm) and the rear up to 2 1/2" (6.4 cm). Available as complete kit or rear shocks only.
