The dip is done and the wheelwell is huge due to other work I've done.

I also removed the spring tower and will probably be going with some 14" coilovers if I can afford them. If not I'll run some leaf springs I have until I can afford it.

I made the front dip disappear and now the wheelwheel ends just under the headlight. I removed the turn signal and will put a new light into the raised bumper ends. The side marker will be shorted about 2"
and reused.

The back is stretched back about 7" so it ends below the a-piller. I have one spot to weld in and some cleanup left to do.

Pictures will come soon hopefully. A friend is going to help me out.

I had another back fusion done a couple of months ago. I have to wear a back brace for about 2 more months.

Re: Pre-runner type suspension stuff

I'd love to see some pics, I remember you talking about it and wanting to do it. but not wanting to be the guinea pig

and I'd definitely save a few months and do coilovers instead of skimp for a bit and do leaves.
pics would be awesome!

bummer about the back man, I was supposed to have surgery about a year or so ago, but for some reason my back problems suddenly disappeared...
I'm sure that'll come back to bite me someday though...

Just wondering if it could operate properly that way. The shocks I just got bought hose is really too long to mount it the correct way.
Just to add to the answer you already got, the oil and air in the reservoir is seperated by a dividing piston, so it makes no difference how the reservoir is mounted.

That's a long hose........

Re: Pre-runner type suspension stuff

Funny that this thread is still floating around, after what, 8 years? Look where we've come.

Re: Pre-runner type suspension stuff

Bumping an old thread because I've been reading quite a bit and not finding what I'm looking for (but this is as close as I've come)


Summary of notes to date (having just read this entire thread).

-275/78 front and 255/70 rear is a common recommendation for damping on all around rigs that both crawl and like to go fast on occasion. Some guys like 360/80 front but this is getting damn firm. Bilsteinís guide can recommend either. https://www.my4by.com/bilstein-valving-guide

-Best practice is to flex test before committing to shock lengthsÖ That said, at about 6Ē lift (reasonable for going faster) 12Ē travel fronts and 10Ē travel rears are common

-Many of the better shocks will require converting to a 1/2Ē eye style top mount. TandJ makes a nice conversion. JKS has an OK one but they sometimes loosen up so TandJ (or custom fab) seems like best practice.

-Lower front shock mount relocation is common too: typically a drop moving the lower mount point outboard of the lower control arm pockets

-7100 Short Bodies seem like the "go to" at high end of the low end. I donít much like how the reservoir hose on the 7100s exit the shock (rigid, pointing up and out). The 5160s (direct fit) or 5165 seems like a better option if one prefers to have the reservoir mounted to the shock body. Compare the orientation of the hoses.

7100


5165


-I canít tell you why sometimes the 7100s have a blue rubber hose and sometime a SS hose.

-Thereís a slight challenge that the Bilstein catalog (https://cart.bilsteinus.com/Portals/...og2020_WEB.pdf) doesnít publish either lengths or damping for their direct fit stuff. Eshocks.com appears to be gone. So if anyone knows of a searchable resource that might be handy.

-It appears that the 5165s can be custom valved but they only come with 255/70 and 360/80 by default. Unfortunately, that seems to skip over the more common valving recommendation at 275/78. More notes on valving 7100s here: https://www.naxja.org/forum/showthread.php?t=994685

-Front spring rates in the 230 to 240 lbs/in are popular (Skyjacker, BDS, maybe Deaver). In the rear, everyone just calls Deaver.


Questions

-Are the stem style shock tops inherently limiting? Iíve blow up several sets of shock bushings which is annoying but not that expensive all things considered.

-Several folks allude to failures of the rear shock upper mounting within the thread. Anyone have pictures of where how it fails? My rig sees quite a bit of daily driving as well so I need to keep the shocks outside (not cutting body for towers) but Iíd love to find a way to reinforce the original mount.

-Iím running Bilstein 5100s in the back of my rig now and the bushings are cracked. Is this a systemic issue with Bilsteins?

-Stupid question, but do 5100s have a top and bottom? Iíve seen them installed both ways.

-If someone were willing to spend some coin beyond 7100 SBs, what's the next step up? I can find some guys talking about 2.5 class shocks but little info on more specific recommendations. Iím not sure I really need it but Iíd like to know. I've been running some longer trail rides and I keep blowing up my top shock bushings so I'm thinking it time to go a notch more serious, the question is how serious?

2.5 class shocks seems like they start around $400 per. One weird bit is that it seems like King or Fox smooth body 2.5s come in notably longer body lengths for a given travel. Compare:
---King 10" smooth body (KRS-PR2510-SSPB) is 18.3" collapsed length
---Bilstein 7100 SB (AK7110SB) is 14.3" collapsed length

-King and Fox seems to rate their damping based on shim stacks. IE ď10/12Ē damping would be a tapering shim stack with 0.010Ē shims on rebound and 0.012Ē shims on compression. (https://www.crawlpedia.com/shock_tuning.htm). Bilsteinís ratings are Newtons of resistance 255 = 2550 compression but I donít know at what speed. Anyone know how to make comparisons between the two rating styles?

Anyways, good resources like this thread are why I love the forums, so I'm hoping some folks can help me out (while in turn I hope the clarifications help others.)

Regards,
-Joel
