Review on 🚲 Upgrade Your Ride with the Progressive Suspension 11-1525 18 Progressive Rate Fork Spring, Black by Melvin Goerge

A cut above the standard HD fork springs. Springs are approximately 50% longer than standard springs and take up less space. The result is better bump-following, much less fork dive when applying the front brakes, and better overall handling. Installation is easy and the instructions are pretty clear. Use only a towel to soften the blow while slowly and carefully unscrewing the connector cap. I forgot my towel and cut my arm when the standard metal spacer popped out of the tube. After removing the metal spacer but before removing the springs, use a ruler or ruler to measure the fluid level in the fork tubes and note how far they are from the top when the forks are fully extended. Drain the oil because it's probably old and not working properly, and because new fork oil is cheap. As a starting point, use standard weight HD fork oil (which doesn't have a clear weight mark) or the lightest fluid (probably 5W) available at your local motorcycle shop. When installing new springs, fill them up to the level of the old springs. On my Dyna it was about 24 ounces on each side. The difference in handling will be significant if only the springs are replaced. If you want a stiffer fork and more damping you can upgrade to the next weight fork oil.
