Lower Forks

How would I lower the forks an inch or inch and a half on my 62 FLH? Just buy shorter springs?

The springs are engineered to work with a certain length fork tube. It would seem to me shortening the springs is not going to be the answer unless you shorten the tubes a like amount. I may be wrong, but in the old days when you installed over stock length fork tubes you also had to install spacers to make up the difference.

If only the springs are shortened the tube will then be an equal distance lower in the fork leg which will limit the available travel and affect the damping action. If you shorten the tubes and springs the spring rate will need to be stiffer to prevent excessive travel as you will effectively be reducing the travel by the amount shortened. You can also potentially run into clearance issues if you are running a front fender. If you want to do it go-for-it, just make sure you are aware of all the related issues.
