Hello Jim, thanks for reaching out. The only difference between the red and blue Road Armor equalizers is the color. The blue is the aftermarket kit, whereas the red it typically factory installed.
As far as your shackles, you will want to measure your current shackles to determine what size you need. Shackles are measured from center hole to center hole. The most common sizes are 2-1/4" long or 3-1/8" long. I recommend going with one of the MORryde wet bolt/shackle kits:
- 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
If you need a different shackle size just let me know. Or feel free to reach out if there is anything else I can help with.
