THOMAS on 5/5/2019

The shocks were on backorder when I ordered them, but still arrived within a week after the order was placed. A black and chrome pair was ordered and they look very nice and high quality. Installation was easy and the instructions that came with the shock indicated what bushing to use with my bike. I called Progressive with a question and found out the weight limit for the standard rate spring was up to 250# for the rider, so I'm glad I called or might have ordered the heavier spring. Very nice ride on the lowest spring rate and on the middle spring rate when riding two up. Overall, a much nicer ride than with the stock shocks.

Important Product Notes

Note: When shocks are different than stock length, clearance must be carefully checked for potentially dangerous interference.
