Well for those of you that are going to attempt to install aftermarket shocks...good luck. My 2022 Tri-Glide has 400 miles on it, thus no corrosion around any bolts. Long story short...I tried like a SOB to get the bolts out of the lower mounting plate and had no luck. I applied penetrating fluid, heat, etc.. Just cant get enough leverage on the top 2 bolts. HD must have applied some super special Loctite on them. I guess I bring my 14.5" SuperShocks to the dealer for installation.
