We have a 96 1500sethat we bought new in 96 a few years back we had progressive springs put in the front with the 15wt oil as recomended.
In 06 we had a lehman trike kit installed with a four and a half degree rake kit it rode like a log wagon no give to the front forks.
Drained all the 15wt oil out and put in automatic transmission fluid,wow what a diffrence rides great now.
So if any of you have a 1500 with progressve springs and a rake kit and it rides harsh try removing what ever oil you have in the forks and replace with atf.
