The etrailer.com Trailer Coupler # CTA-280 that you referenced can have a bit of up and down play like what you described when mounted to a channel like # CTA-CB126. As long as you have the bolts tightened down to the correct torque spec (159-212 foot pounds for the included grade 8 bolts) this is not cause for concern. Normal manufacturer variances such as the amount of powder coat applied can result in this type of movement.

Hey Ron, good to hear from you! How long are your current U-Bolts? The U-Bolt Kit #APUBR-8 could potentially work as it has 7" long U-Bolts, but it really boils down to what you currently have. For something longer we have the MORryde U-Bolt Kit…
