Does anyone have any experience with sliders compared to shackles? I've read a few threads on them else where and wanted to see if anyone regrets converting to them. What's the ride quality like also?
 
 
This 40 has them up front:


There is an ex-member here (got pissed off, threw a fit, deleted all of his stuff from the forum) that had them front and rear on an FJ55 with 54” springs from the rear of a 99 GM Tahoe SUV, and claimed it rode like a cadillac.

This is his truck in this thread:

Two benefits I see to them:
1. Lower ride height
2. Protect from bending a leaf spring by bashing it into

Downside I see:
Less flex due to limiting range of motion and less leverage on bushings.

Huh I was wondering what happened to that guy. I liked his build, but I guess he didn’t like it here. Oh well

Threw a tantrum, took his toys and left the sandbox.
 
I can understand. We all have our breaking points and the community in this channel seems to be quite a bit more welcoming on average than the other channels. I’m afraid of auto check removing the “40” from “FJ” anywhere else.

Thanks for sharing these shackles. I’ve never heard or seen them before. What is the benefit of these over the Teraflex shackles?

Likely only benefit to slider style is lower ride height. Never used those style shackles (revolver or double shackle) but they would allow far more droop and flex of your suspension if shock lengths and other common interferences accommodate.

When they first came out they were headed for the mount of droop you’d get Then the naysayers claimed that thee extra droop was unweighted and therefore useless. No expeirence, just what the internet rumors said.

I don't know if I buy those arguments. "unweighted"? Gravity doesn't care, its going to pull down on that axle regardless of how its attached to the frame, how its attached will dictate how far it will droop. A properly setup suspension should utilize a bump stop to transfer force from the tire being compressed to the tire that is drooping to help increase droop and traction.

That is an interesting opposition. I’d wonder though if the tire approaching unsprung weight really matters whether it is flexed more because that tire is either touching the ground or not at that point, but wouldn’t the opposite side of the vehicle have more tendency to be better planted?

You said this better than me, and you hit “post reply” quicker, too.

Like I said, I have no experience. I was intrigued when I first saw them, but not enough to get some. Everytime they pop up in conversation I listen to what people say. At best they seem a mixed bag, but personal experience may vary. They look neat.
 
I have a pair of Liquid Iron sliders in the shop for my 69(ish) build. Only reason is to attempt to build the lowest spring over (with longer softer sprngs possible. Got delyed, bought a new shop this year. I'm not concerned with wearing them out, but it won't be a daily driver.
 
I've decided to build my own sliders to save some money and work on my fabrication skills. If they aren't a complete embarrassment, I'll post them up.

Found this great website with a how to guide and some flex pictures if anyone is interested.

 
You should post pictures either way. It’s helpful to know what doesn’t work, which reminds me that I need to post pictures of my top extensions. I thought that I grabbed 18ga from the shelf but it must have been 22ga and it lost all rigidity when I tacked it together. The top is back under my house where it has been for the past 20+ years. Ha!

Good luck with your sliders. I can’t wait to see what you come up with, even if it doesn’t work. Make a tree of learned experiments.

I know this a thread on spring sliders but figured I'd add my opinion on the revolvers here. My cruiser has had the revolvers since the 90's (before I was born) and I even recently grabbed a set that was still new in the box off of craigslist to replace my 20+year old ones. The main issue I see with them is that they almost allow too much travel. The "arc" that leaf springs allow the axle to travel seems exaggerated. An example would be when one tire is almost completely drooped out it is halfway under the rocker.
What's always had me scratching my head is biggest complaints about the revolvers is their unloading on descents and poor on road handling. I haven't experienced the unloading issue and the on road stuff is not an issue either. I have a tall, short wheelbase vehicle and I drive it as such so I don't notice excess body roll.
When I broke my pinion at rubithon this year there was a lot of "those damn shackles" from people that came up on me while broken. I still think it was the pinion being 50 years old and 20-25 yo. springs wrapping on a climb that broke my pinion and not just the shackles but who knows.
 
I've ran revolver shackles on my 40. They were HORRIBLE in the front. I couldn't keep the front axle centered under me when I steered. In the rear, they weren't bad at all. I did have the feeling of them unloading on descents, but what I was dropping into was so steep it probably would have felt that way regardless.
