The 14" REVO ARC is a great option for those looking to increase their travel and/or seat height from their existing suspension setup, as the 14" REVO ARC offers 4" of travel, significantly more than a stock shock. However, in order to run a 14" shock, there are some supporting modifications that are needed for this fitment to work correctly on FL Touring models.

The first thing that will need to be addressed is the exhaust. Because of the additional length of the 14" shock, pushing the swingarm down further, the axle nut sits lower and will contact the exhaust slip-on. Therefore, a shorter exhaust slip-on will need to be installed on the motorcycle to prevent this from occurring. If you desire the 14” shocks you will need to have an exhaust system that is short enough that the exhaust tip stops BEFORE the axle nut. 

The next thing to address is belt tension. There is an acceptable variance in belt tension, meaning the swingarm can move up and down without negatively affecting belt tension to an extent, however, with the 14" shock the belt will more than likely need to be re-adjusted to account for swingarm movement outside of the previous range of movement the belt was adjusted for. It is important to double-check your belt tension with the 14" shocks installed by referencing your Harley Service Manual on this as they are different from bike to bike.

The last point to consider is the ride height in the front of the bike. Although not a requirement to run a 14" REVO ARC, we do recommend going with a +2" fork tube on the front of the bike, coupled with the +2 AXEO kit we offer. Running the AXEO +2 compliments the 14" REVO ARC rear shocks increase all-around travel, and maintains a level chassis to optimize handling and control.
