Question:
I own a 2025 Grand Design 2670MK travel trailer. I want to install the CRE3000 equalizers you sell and replace the OEM shackles. The center to center measurement on the shackles is 2 1/4. My measurements on the wheelbase however show 36 every way I measure it. Concerned since I do not see the equalizer offered in a 36 wheelbase. Please advise

Rick, unfortunately it does not look like there is going to be an CRE3000 kit for your trailer based off of your current shackle strap length.
You can still upgrade your shackles with the MORryde Suspension Upgrade Kit for Tandem Axle Trailers # MR46ZR. This kit includes (8) upgraded 2 1/4" shackles, (8) wet bolts, (6) wet bolts (for suspending equalizers and springs from the hangers), (14) bronze bushings, and (14) locknuts.
