Hey Russell, thanks for reaching out. The MORryde Suspension Upgrade Kit # MR76ZR comes with 3-1/8" long shackles. It will work great for you provided the shackles on your StarCraft travel trailer are also 3-1/8" long Center hole to center hole. The common shackle sizes are 2-1/4" long or 3-1/8" long so please confirm which one you have and select from the following:
- MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 2-1/4" Long Shackle Straps # MR46ZR
- MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 3-1/8" Long Shackle Straps # MR76ZR
Are you wanting to replace your equalizers and leaf springs as well?

Hey Russel, This MORryde suspension upgrade is going to make you and the contents of your trailer VERY happy! I put it on my 34’ Grand Design along with 4 new GoodYear tires and no doubt,it was the smartest move ever. The piece of mind knowing my rig is SO much safer now makes owning an RV so much better. I did the entire job in my driveway by myself with a floor jack and a small bottle jack,some common hand tools (1/2” socket set,hammer,a punch and some grease) did the whole job in less than 3 hours. Watch the e-trailer video a couple times and go for it. You’ll be surprised at how easy it actually is, and the rewards are worth every penny! Good luck!??
