Installed progressive 11-1525 fork springs in the 2010 FXDWG. Followed their instruction sheet with oil level but found the supplied spacer gave me no preload at all, about 3/4" under the top of fork tube. Progressive tech help suggested using a longer spacer so that it protrudes at least 1/2" above the fork tube giving it 1 1/4" preload. Stock spacer is 4.63", used some pressure PVC tubing cut to 5.85". All seems ok. Anyone got any comments with similar experience?
