    i ran a solid bearing once and as long as i am dd’ing my truck i’ll never do it again… basically a constant hum and vibe. it did make the driveline feel super tight though def a good idea for a dedicated play truck

    I have no hum or vibes. The diff may be that this CB is mounted in what seems to be modified leaf spring bushings

    yup big difference, mine was one of those mcmaster carr bearings, bearing in a cast housing bolted directly to the shitty oe cross member. could feel the driveshaft in my ass…wait that didn’t sound right :anonymous:

    where did you get that one ? i’m going back to a two piece when Harry does my 4 link and frame boxing etc so i need to figure out what to do for a carrier bearing. OSide Driveline mentioned something they had but it just sounded like that Ranger bearing a lot of folks use

    For those of you that have/still have this bracket, what did you do with it? Currently at full droop the bracket needs to angle down but at full stuff the diff pushes it up. I can’t see a way to angle/mount it so it works both ways.

    Currently I just slightly loosened the bottom bolt and just let the bracket pivot when it needs to. Maybe a little bushing in between the two and a little rubber bumper where it connects with the diff. Other than that I don’t know what to do with it.

    Does anyone know a good thread that discusses valving of shocks? I cant seem to find any but feel like people on here would be "experts" with good intel. I was told to ask in here, despite being a peasant mid-travel.

    The reason I bring this up is because I am trying to dial in my front end of my 2.5 King Ext w/ adjusters. My neighbor showed me the art of revalving, but I assume one of the TW guys knows much more than him even. This is what I documented along the way to keep track and am mostly happy with it, but already wish I went stiffer on the compression valving.

    While doing this, I swapped springs to 650lbs to account for the armor/ AGM battery / steel bumper / etc and went from 1 1/8" preload on both sides to zero preload on passenger side and 1/4" on driver side. Going to go up another 1/4" I think, but will figure that out later. Below are tables showing what King valves their shocks at from factory versus what I did.

    Never make multiple changes at once. You made 3. Spring, compression and rebound.

    What is it you are looking to get?

    Point taken on making one change at a time, however I just am not able to tear apart the front end multiple weekends in a row. Ultimately, I am trying to be able to handle larger bumps (or small whoops) at a higher speed.

    With factory valving, it was wayyyyyyy tooo soft on compression and too much restiction on the rebound... With that said, we did not know what most guys start with as a baseline. So this is my baseline-- pretty confident the springs were a necessity with my "prelander" setup, and honestly not as much of an increase in stiffness as expected.

    I'm assuming we're looking at the valve stack with the piston at the bottom? How much bleed do you have?

    Explain what you did with your rebound and why? Am I understanding 10’s would be the big shims and the 8’s would be the small? As mid travel these trucks really do need a bit of rebound valving to reduce how hard they top out. The top out is incredibly harsh. You’re super light on the rebound side from what I was as mid travel. But then again, it’s not a one size fits all deal. Which is why you don’t find much for resources.

    If you’re unable to take the truck apart constantly to get it right. I would suggest sending the shocks out to down south or similar so they can tune them.

    Personally, I’ve had my shocks out 6-8 times in a weekend while trying to dial things in. It takes a ton of time to get right if you’re not a pro.

    The shims were stacked

    Bleed? Is that reference to the nitrogen PSI? Sorry, first timer that leaned mostly on my neighbor who has more experience with this.

    Correct, the only changes made from the factory valving was reducing 2 15's to 8s with the theory/suggestion of getting the droop to catch up at speed. I should get an idea of how this pans out this weekend, have only done some urban tests near my local airport's big dips. Its leaps and bounds better than original from what I have felt thus far, but still pretty damn plush. I assume the higher speed stuff will continue to be an issue.

    As far as tearing it apart 8 times in a weekend, thats awesome and for sure the way to go, but unfortunately that will have to be stretched out over the course of a couple months. Instant satisfaction would be great, but mine will have to be a work in progress.

    To be honest, going down to 8’s wasn’t the right move.

    starting with the biggest, try going 10,10,12,12,15,15 on rebound. See how that goes for you.

    On compression if it’s too soft I would try a stack of straight 15’s to see if it improves. If it’s still too soft go to 20’s on the 2 biggest.

    That sounds fair, and hence why I posted. Being that I'm only going off my neighbors knowledge and the little I know, I am open to all constructive criticism. Obviously a midtravel setup with potentially drastic different curb weight, a lot of variables inbetween me and a LT setup.

    I am currently on Camburg's list to have their Trail Series +2" setup (basically a faux LT-- utilizes midtravel shocks for 13" of travel) installed sometime in March, but since rebuilding these fronts, I see the huge benefit of spending the extra cash and go full LT with bypasses. So I am most likely furloughing the Trail Series and saving some more to go all the way.

    Their race kit is only an extra inch. So that’s pretty good. I was curious when you said 13” since that’s what my LT kit is. Was surprised when the +2” was the same. :rofl:

    Bleed is the amount of fluid you allow to bypass the main piston & valving. This effects both circuits in the shock (compression & rebound). Typically bleed is created by holes drilled in the main piston.

    Im going to assume you have two bleed holes open, probably in the realm of .098” holes but if may vary slightly per manufacturer.

    What you’re likely going to run into is trying to find the balance of ride quality and damping control for harder hits. Pursing increased damping for whoops, etc will typically create harshness is other areas, assuming you’re intending to daily or street drive this truck. Finding a balance is tricky when using a single shock and no bypass technology of any sort. That’s what you’re trying to achieve by running a flutter, which creates other unwanted characteristics.

    @906taco brings up a valid point though about harsh top outs with an MT setup. This is common due to the limitation of travel. Just something to be aware of. You’ve already increased spring rate & preload which will already generate more force. You may want to consider adding limit straps
