Question:
I am upgrading my suspension hardware on an 18’ tandem axle trailer. Your kit K71-359-00 looks like the correct kit except my shackle links are 3 1/8” oc and the kit includes 2 1/4” oc links. Do I need to buy the longer links or can you swap the smaller ones out in the kit with the longer ones?

Hi Andrew,
I wouldn't suggest changing to 2 1/4" shackles because it will significantly change the angles of your suspension, which will affect the ride. Thankfully, we have a suspension upgrade kit for 3 1/8" long shackle straps, which is the MORryde Suspension Upgrade Kit for Tandem Axle Trailers part # MR76ZR. The shackle straps in this kit are heavy duty at 1/2" thick and pair perfectly with the included 9/16" wet bolts (with zerk fittings) and bronze bushings.
What kind of trailer are you upgrading the suspension on?

Thank you Claire. I ordered the MORyde kit that you suggested, just waiting for it to come in so I can get started on it. Hopefully this will last longer than the original setup that uses nylon bushings, I have replaced those twice. The trailer is a 2024 RC enclosed cargo trailer that is used five days a week for my delivery business.
