Question:

I was curious if you could help me find replacement leaf springs and shackles for my 2012 Eclipse Attitude Toy hauler. It has 3 6k axles. Thank you.

Hey Mordechai! I can help you find replacement leaf springs and shackles but you will have to get some measurements. For the leaf springs you either need to measure the flat length or get the spring eye to spring eye measurement. Both of these are explained in the article linked further down on this page.

For example, if you find that the eye to eye measurement is 25-1/4" (accounting for it flattening over time) you can use the 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/4" Long # e34SR. If you have a different measurement let me know in the comments below and I'll see what is available that matches.

For the shackle straps, you need to measure center hole to center hole. More than likely they're either 2-1/4" or 3-1/8" since those are the standard. I highly recommend upgrading to heavy duty shackles and wet bolts since you're already replacing them. You can use the MORryde Suspension Upgrade Kit for Triple Axle Trailers - 2-1/4" Long Shackle Straps # MR86ZR or for 3-1/8" # MR26ZR.

Any big trips coming up with your toy hauler?

Hey Mordechai, were you able to get those measurements for your Eclipse Attitude’s leaf springs and shackles? Once you have them, I can help confirm the best match for your setup. Let me know what you find—I’m here if you need a hand narrowing it down.

@RobinH finally got around to it! I believe my measurements are: 25-1/4” eye to eye 1-3/4” wide 4 stack leaf 2-1/4” shackle (maybe 2-5/16”) I almost always tow with full fuel, water, and a sxs in the trailer. Roads where I go are not kind. So a stronger leaf/shackle would be acceptable but I would like to keep it simple. Thank you.

@MordechaiY the # e34SR will work and that extra leaf will make it a little sturdier even though it has the same rating. You'll be sitting 3/8" higher if the axles are on top of the leaf springs, but it isn't going to throw anything off. If you want to move up in capacity the 6-leaf # TRU52FR will work as well. I would definitely get the # MR86ZR so you don't have to worry about those small components failing.

@RobinH should worry about getting new u bolts and hardeware? As well as equalizers to?
