We don't have a way to look that up so you would need to measure yours to be sure. The part # MR46ZR is 2-1/4 inches long shackles which is a very popular size so there's a good chance it would be what you would need. The other really popular size is 3-1/8 inch like what the part # MR76ZR has. Both of these kits come with bolts, bushings, and nuts too.

If your current shackles are close to one of lengths of these kits but not exact just go with the one that is closest and it will be fine.

Answer 6

Well shackle length is mainly based on the height difference between the front and rear hangers. The rear hanger normally doesn't hang as low as the front so that the shackle can offset the difference and add the ability to move. What is the…

Thanks for the pictures! Since your 2022 Grand Design Reflection 303RLS came with the CRE3000 equalizers you will need three of the MORryde X-Factor Crossmember item #MR33WR. It looks like you have the standard 3" wide frame hanger so all of the…

The hangers you currently have on your trailer are ones I have run into before. That being said, I spoke with MORryde and the #MR27ZR will still fit your trailer, but there is a modification that will need to be made. You’ll have to trim according to…

I reached out to MORryde and the MORryde Rubber Equalizers for Tandem Axle Trailers - 35" Wheelbase - 8K #MR27ZR you were looking at is designed for 35" axle spacing and would not work with your trailer with 36" axle spacing. My…
