I just got a set of 13.5 inch ODC Monza rear piggyback shocks. My front end is stock height on my 2011 Dyna Super glide custom. But has the racetech gold emulators with racetech high rate springs. I am going to be swapping about the front end I have now which also has dual disc brakes using brembo .484 radial brake calipers using the krause axial to radial mounting brackets for the ODC Monza inverted front end. Ive seen some forum members get +2 when ordering their inverted front ends after installing 13.5 inch rear shocks. What is the benefit of getting +2 up front over getting a stock height up front? Or would having 13.5 inches in the rear and stock height up front actually benefit better with quicker turn ability?

 

Increased Lean angle. More suspension travel

 

You should probably discuss this with ODC/Krause, or someone really familiar with similar setups. Changing the height relationship between front and rear changes the overall geometry of the bike, which may be better for you or may be worse. In very basic terms, raising the rear of a bike more than the front usually results in quicker steering at the expense of straight line stability. Rake and trail change. But this is overly simplified, which is why you should discuss it with someone really familiar with your goals and setup. One advantage of going longer: If you don't like the setup, you can drop the tubes back to stock height in your trees (if you don't have clearance issues with bars or anything). You can't make the shorter ones longer!

Good luck, sounds like you're building something fun!
