    we recently purchased a new Rockwood 1640esp pup and we love it. the lift gives it a better chance at life off-road, and that's good because of where we like to go with our Jeep. but looking at the suspension, it seems to me that it's mostly a gimmick lift to just make it look badass...

    the leaf springs are pretty tiny...not very wide, and only about 2 feet in length. seems like over the long haul, these will eventually fail or cause issues if we actually take this thing off road on trails and not just dirt roads.

    has anyone cut off their stock leaf springs and put in something beefier? I'm thinking I could find a setup for a Jeep YJ or CJ for decent cost and weld in new perches and hangers. they'd be wider and longer, and maybe give a better ride? I'd maybe even think about shocks at that point. I'm just thinking that a few years down the road those little ones will be hurtin...

    thoughts?

    keep in mind those springs are for something roughly half the weight of your jeep. Once you do a few offroad adventures with it, and see how it performs, THEN i would evaluate whether or not I needed to upgrade the suspension.

    agreed. gonna test them first and see. the CJ springs would fair pretty well as the old Jeep CJs were around 2600-2800lbs. our camper is 1680lbs dry. probably be a little stiff, but I could always find some used ones that had been flexed out a bit. :)

    There should be a lift/Jeep/truck suspension shop somewhere near you. Best place to get the leaf springs and good advice for what you’re thinking. That’s what those guys do. Congrats on the new pup!

    Keep in mind that when going to a heavier spring you are putting a lot more stress on the pup. You will find that it bounces more because of no spring give. That's when things start to break apart

    The leafs that are on it are designed for it.
    They simply do an axle flip and bolt on the all terrain tires when it comes to the dealer.

    Jeep springs would be too stiff and the trailer would probably bounce all over.

    I hammer my pop up pretty good. The springs are fine but I wish I had shocks to dampen the bounce. It’s lifted with larger tires. BB536923-5171-43B2-A464-A4E275314D42.jpeg

    I've considered shocks too.
    My sons trailer has shocks on it, makes it tow really well
