I am going to install the Triglide triple trees on my 2003 FLHTC. I will use fork spacers instead of the longer forks. The spacers I have are 2" long. will this have any negitive impack on my installation?

It'll be a bit harder to get the fork cap nuts on.

my liberty tree came with one inch spacers - 2 inch spacers may raise the front a bit and that will "increase" your trail - you may need to futz with the rear preload to keep the thing level

Will the "increase" trail make it easier to steer?

to make it easier to steer you want a decrease in trail..

many things affect trail - raising the front end in relation to the rear will increase trail, lowering the front end in relation to the rear will decrease trail.

so for example - if you swap the rear tire for a 145r15 tire - that lowers the rear - so in that case with a liberty tree you leave the spacer out and the whole bike is lowered a inch and the trail is reduced the intended amount.

if you run a standard rear tire - then you want to install the spacer so you dont decrease the trail too much.

the idea of the spacer is that as you change the rake and push the front tire forward it takes a longer fork to have the same ride ht. the hd trees are set up to work with the longer lowers to get the same affect as the liberty spacer does. each mfg of raked trees has a "set" of parts that result in the original ride ht with the increased rake - the only reason to futz with it is if you are making other changes.

in my case with the smaller rear tire i lowered the front to match.

measure loaded front frame to ground clearance - then do the change and see what that number is and adjust from there. you want it to stay the same UNLESS you are changing the rear ride ht at the same time.
