I know alot of you guys are using 13"-15" rear shocks. Did any of you raise the front aswell? If not, how does the taller shocks affect handling/steering geometry?

Will raising the rear 1,5" without raising the front make the bike unstable?

 

I added 1" longer rear shocks the same time as installing standard height progressive wound springs in front. Noticed no handling difference beside no longer scraping while cornering.

 

I have a 2005 Super Glide...changed the rear shocks with 13.5" Progressive's and Over 2" fork tubes in front (Similar to a FXDX T-Sport).

 

13.5 shocks on my FXD, Maybe a little quicker turn in from raising the rear, which is nice, but nowhere near unstable. Love the better ride and extra ground clearance

 

I use longer shocks...a larger diameter rear wheel and a smaller diameter front on my FXDWGI and it's still not unstable...just sportier and better suited to aggressive cornering.

 

I did the 13.5" progressive 970's on my rear and just did Speed Merchant fork adjuster to stiffen the front and the bike feels much better than stock.

 

Thanks. That's what I was hoping for. Just put in an order for the Bungking rear shock lift kit.


I was looking for some 13"-13 1/2" shocks, but I just realised that my 12" JRI's have the same amount of travel as the Øhlins 13 3/8" (88mm), so I see no reason to spend $1000 on New shocks


I'll let you know how it handles...

 

Hello from France! Same question.
On my 2015 Dyna FXDL , I have new longer rear shocks :13.5 .
I am thinking to add 2" extension tubes to the fork.
What do you think about this solution in order to keep the same genuine geometry?
Thanks.

 

I think the Fatbob has the steepest rake of any of the Dynas in the lineup. I've been running 13" shocks for over three years on my Fatbob and have not experienced any negative handling issues since raising the rear end. I went with a quality JRI fully adjustable shock and I wouldn't think twice about running longer shocks on these bikes. The improved ground clearance along with a plusher ride from a premium suspension makes hammering around on this baby really worth it. I wouldn't hesitate to make the change.

 

I've talked to two professional racers, and they both told me that going to 13"-14" will dramatically improve the handling, and no additional length in the front suspension is necessary.

Of course, if you want to improve the performance of the front forks, by all means do some upgrades, but the key point is that you don't need to go longer in the front because you go longer in the rear.

In fact, one of the best changes from going longer in the rear and no change in the front is that the front fork rake and trail changes make the bike corner and respond much better.

At the moment I'm pretty much decided on 13.5" Hagons. Can't wait!
