Inexpensive and quick to install, Burly Lowering Blocks are the time tested method to drop virtually and HD without breaking the bank. A bike lift and a few wrenches are all that it takes to pull up to an inch and a half out of the rear of most year Sportsters, Dynas and FLH (Baggers). Simple bolt-on installation; comes with mounting hardware. Designed for OEM and most aftermarket stock length shocks. Made in the USa. NOTE: Rear lowering kits are not to be used in conjunction with shorty shocks or low-profile shocks. NOTE: Fender-to-belt and tire clearance must be checked along with frame and exhaust clearance. Saddlebags may require spacing. XL models are lowered approximately 1in. ; wheel travel is reduced 1/2in. for stock. Do not install on Sport, Deluxe, Customs, Huggers, or Low models.
