Solid Axle Swap BS Thread

I'm not sure. I have Johnny joints on my lower links and heims everywhere else. It's not bad at all on the road. I just made the journey to KOH and was perfectly comfortable. I can't imagine 1/8" of polyurethane in a rod end is going to be a deal breaker for you. The problem with rebuildable joints is just that, you will have to rebuild them. Heims require little to no maintenance (by little, I mean a spritz of WD40 every so often) . If heims get noisy due to lack of lube and really develops some major play in it, you swap it out for another heim. Eventually I'll make the change over on my truck. I've seen 1.25" heims in person and they are absolutely massive. There is a reason nearly every rig at KOH uses them in multiple races/seasons.

 

The only thing is with a 4 link, I'd like to triangulate the links more at the frame. With a 3 link, I don't think I'll be able to triangulate them as much since the gas tank will still be in the way...

 

X2.

 

Hmm so sounds like I'll give the heims a go then. Should be ordered by end of
Month.

 

Just placed an order for my CO's... 14" King 2.0s with resi's 150 / 100 spring rates. Hoping for 5" uptravel at 25" frame height.

 

Look at you gettin shit done lol!

I've been researching...

There is so much to learn about suspension, ridiculous.

 

I know, and I feel like I need to know it all to set up a proper 3 link the first time and not get vibes or death wobble.

 

Why such light rates? I would guess you'd be more in the 150/200 range with the 4 cylinder. I have 200/300 on my truck now and will probably step down to 175/250 to get some preload on them but only after I link the back. I feel like its useless to tune the front for go-fast when you have leaf springs out back.

 

Keep your lowers as close to flat as you reasonablely can. Stay close to the 30% rule upper around 30% shorter then your lowers. At least 6+" if vertical separation between the uppers and lowers triangulate the lowers at the frame if possible. drag link and pan hard the same lenght and plane.

That should be a start

 

Maybe the 4 cylinder i was thinking the same thing.

 

Alright, thanks! What's a general length the upper and lower links should be? I know it varies but just wondering lol. I haven't even began using a calculator.

 

My lowers are long at 43" eye to eye. I can't remember what my upper is i think it's around 30" I set mine up so that front and rear links were the same length just in case I destroy one I only need one spare.

 

I didn't choose the rates. Ben @ filthy motorsports did. He said he's usually 95% right on his numbers. He wanted me at a 125/175 but unfortunately king doesn't make #25 increments so he's going to valve it differently. Worst case scenario is I do a spring exchange for $40. And run 150 / 200. Who knows let's hope he's right. I'm not trying to go fast at all. Trail rig only rock crawling only. Softer will flex better.

 

when I bough springs I wanted 100/150 but the lowest I could get and 18" spring in was 200# so my 16" spring is 150#. I needed 2 inches of tender coil to put me at the ride height im at now but when I change up the front end I wont need em anymore.

 

I'm going with PAC springs front and rear when money permits. They have 25lb increments for the most part. Did you get corner weights and unsprung weights for Ben? If you aren't trying to go fast, really any spring will work but some will ride nicer than others (softer). A lot of go fast rigs will tune the shocks for stiffer compression and light rebound so the coilover springs have an easier time "pushing" the axle/tires/wheels into the next hole. Maybe he's valving yours the opposite? Then again, if your springs are too light, you can valve stiffer on compression and it'll ride like you have heavier springs. The main thing is to get some compression on the springs at full droop at a determined ride height and valve the shocks until you're satisfied with the ride. My rate is too heavy up front because when I put compression on the springs, the truck sits 4" higher and I have to run tender coils to keep the springs from flopping around at full droop. Coilovers are fun

Don't you have a V6? Can't you just preload the springs to get the ride height you want? Seems a little light for a V6.

 

Preload?? not sure what you're saying there. Not trying to be an idiot here but I just adjust the springs down till I achieve desired ride height. Doing that let my springs fall loose and I still had 2 inchs of droop left. so I put in a tender coil but like I said when I move my coils up I wont have that issue the tenders will just be there for looks.

And yeah I have a V6 and full front bumper and winch on it.

 

Preloading the springs at full droop. So when the shock is fully drooped out, you still have pressure on the springs, they don't flop around everywhere. You have a monster truck though so you're the black sheep with a wild ass setup LOL

 

There is alot to the CO haha, and I know very little. He said to call him when I get the CO's put on there and he will walk me through a bunch of measurements and shit to find me the right springs if I need them. He said I can go with PAC springs too, they are a tad more expensive and I'll just have to pay the difference if it comes out to needing them.

I just went with what he suggested so far. I told him I'm about 1300 front corners and 1k back corners putting me at #4600 which is what my truck weighs. I based those numbers loosely off of what I've read from norcalPRs build. I told him all my specs on the truck and what I use it for so he based it off of that. He said I will "probably" need about 3" of preload? to get the truck to ride height of 25" with these springs. He said at full droop I shouldn't have any flop of the springs so no need for tender spring, but he said it'll probably rub the shock body slightly as most long springs do. There was alot of tech talking to him and most of it went over my head lol

 

Okay yeah I got ya. Like I said earlier if I had done that I would be 2-3 inches higher than I am now and that's no good. trying to get the truck to be a bit lower. Monster truck eh??? I like it
