Sulastic rear spring reviews? Please post your results?

^Never had any on a truck, but jeeebhs...I get enough violent wheel hop on dry pavement, don't need any on wet roads too!

Makes sense though. You put traction bars on to reduce rotation of the rear axle and this just takes the moment resistance out of half the axle mounts.

You can have mine. Waste of money and dangerous. Not bad without a load. But with the 5th wheel hooked up, if I got in something slippery while accelerating from a stop (painted crosswalk, bit of sand, gutter in the road with a splash of water) and the tire spun - there was unbelievable (dangerous) wheel hop which shook the truck and trailer violently. Didn't need to be accelerating very hard or aggressively as this product kept the wheel from staying planted, inducing violent wheel hop. I put the factory shackles back on and have not experienced this since.

Probably no review, since the truck already rode like a buckboard and likely rides just as stiff with the camper on.
Sulastics only help with empty ride and Mrs Blanco1 thought it was rough with the camper as I recall. Sulastics don't help the ride with a significant load. If anything they add to the load carrying capability as they take weight and deflect "first" then are not performing their primary purpose once the vehicle has a load.

Coil over shocks weren't helping the situation either, unless they were needed. That and if the rear tires were aired all the way up and that 12klbs of tire capacity wasn't needed then they were adding to the rough ride.
Essentially there's a few primary things the OP could have done to soften the ride with the camper on and this was not one of them.

Blanco,
If you install the Sulastic shackles it would be good to come back here with a review.

That you can count on!

I love to post pictures & share info on my Projects.
& I' sold off most of my Projects.

Blanco,

Doing good monotube shocks in conjunction with Sulastics, your dually will ride at least as well as a stock 3/4-ton, if not better.

Thats my current plan, just figured I'd ask you people your thought on the product before spending the money.

I've been thinking an adjustable like the Rancho 9000 sounds like a decent way to go being adjustable.

Yet i do like Bilsteins.

When you ditch the coilover shocks, get a good Monotube shock. Bilstein, KYB, Fox etc. Those will for sure make the ride softer, while providing better loaded control at the same time. But "shocks" (which are really dampers, and don't actually absorb shock....) won't help with the harshness that gets transmitted through leaf springs, and that's where the Sulastics come it. The act like an isolator for higher frequency vibrations, which we feel as harshness, or banging, when you hit an expansion joints cracks etc. And they also help reduce wheel hop on washboards (but the nature of a 800 pounds of unspring weight being a dually, it'll still happen, just not as easy).

I dont understand why you have coil over shocks to begin with. Add a extra $100 and get them gone as well.

Yeah, thats part of the Plan!

I bought the truck with those coilover'ed shocks already installed.
