Matt from Bleepinjeep put those on his MJ. Hasn't given a full review on them yet but he has a video talking about them before install. He may review them when he reveals the finished truck.

DirtyComanche Posted April 27, 2018 Share Posted April 27, 2018 I don't think they're a good idea, too many wear points, and they do not allow the spring to move how it naturally would when the axle is articulated. Their intended application was circle track racing. Pretty much the exact opposite of 4x4ing. Link to comment Share on other sites More sharing options...
Smokeyyank Posted April 27, 2018 Share Posted April 27, 2018 Check on NAXJA, a few guys run them. Not a ton of info for them but I like the idea. So far from what I've heard the biggest downside is losing some departure angle and they can get hung up on rocks vs regular shackles. But the flex and overall streetability is a major improvement.

yxmj Posted April 27, 2018 Share Posted April 27, 2018 I had them on a YJ I just sold and really like the ride (YJ's are leaf front and back with the front leaf mounted backwards) I am building another now and intend to use them again. And when the MJ's suspension needs attention it will get a set as well Link to comment Share on other sites More sharing options...

They were made for circle track racing originally. They've just become trendy in some other applications in the last few years. Link to comment Share on other sites More sharing options...
HOrnbrod Posted April 27, 2018 Share Posted April 27, 2018 How long will that noisy sliding block last? 100 miles or so? Link to comment Share on other sites More sharing options...
yxmj Posted April 27, 2018 Share Posted April 27, 2018 How do you know is it is less or more noisy than a shackle working in the same situation? I think the noise is coming from the spring not the block? My blocks I made myself out of a product call Delrin.....they lasted thousands of miles ( I pulled trailers with that rig) and were still looking good as I watched it drive down the road with it's new owner. ..and I have made blocks for slipper springs on 5000 lb trailer axles from a cutting board as well Here is a Thread that talks about some on an XJ https://www.cherokeeforum.com/f67/leafspring-sliders-vs-shackle-142993/ Link to comment Share on other sites More sharing options...
HOrnbrod Posted April 27, 2018 Share Posted April 27, 2018 Zero experience so I can't comment yea or nay. It looks like they would be a lot more stable than shackles for cornering at speed though... Link to comment Share on other sites More sharing options...

Which is what it was intended for. Most of them do not last that long on the street. It's not like you will get 100K+ miles out of them like an OEM shackle.

yxmj Posted April 27, 2018 Share Posted April 27, 2018 Actually slipper springs were standard equipment on quite a few large trucks back in the day (before being utilized in dirt track and drag racing) and even today can be found on utility and heavy duty equipment trailers. Search the inter-web there is an interesting read out there about how this type of set-up is superior to a shackle as it allows the spring to run in a true linear motion as intended....the shackle when revolving puts less/more/less stress on the spring as it moves through its half arc of travel.....with the slider the stress is smooth as it allow the spring to stretch out into a straight line......like I said linear Link to comment Share on other sites More sharing options...
saveevryjp1998 Posted April 27, 2018 Author Share Posted April 27, 2018 I seen the sliders on the bleepin jeep and thats why I brought this up. I think it will be a great setup. There is a reason why jeep speed racers use it. It seems like binding would hardly be an issue. The bushings are cheap and easy to replace. I pretty sure you can buy it in sheets and cut yourself. Servicing would be extremely simple. Many aftermarket companies use these bushings in the front linkage although I have not tried it there yet.

Dzimm Posted April 27, 2018 Share Posted April 27, 2018 Like yxmj said, those blocks are made of delrin. We used to produce parts made of delrin here at work until we found out what happens when it sits in a hot injection molding machine for a while.... The safety guy made us stop using it when the machine's feed throat made a nice big dent in the 30ft ceiling.. Anyway, from the experience I have with it, I see no reason it won't last quite a long time in this application. Link to comment Share on other sites More sharing options...
