Question:
Hi, I am looking for information on the difference of bx1121 vs bx1115. I understand the 21 is for 2004 jeep Grand Cherokee and the 15 is 99-2003 WJ. I would like to know if you guys have a spec sheet on them with dimensions? I am looking to install a bx1121 on a 2003 jeep wj and want to see what I would need to modify to get it to fit Thanks for your help

Hey Nick, thanks for reaching out!
The Blue Ox Base Plate Kit # BX1115 is what you want to go with for your 2003 Jeep Grand Cherokee.
The basic design between the Kit # BX1115 and the Kit # BX1121 is the main dimensions and mounting bolt pattern for it. I don't have these readily available, and since the 1115 is a custom fit it wouldn't make sense to try to modify the 1121 on your Grand Cherokee.
You're welcome to purchase the 1121 and try to modify it to fit your Jeep, but I don't recommend doing so.
