OME spring question

Posted in Suspension but got no responses. So I figured I try here for more exposure.
I'm picking up a used pair of OME Dakar EL095r medium duty with an extra leaf added to make them equal to the heavy duty.

My questions:
If I want to run a ubolt flip kit, what length ubolts will I need. Will 8.75 be long enough? Are longer bumpstops needed?
When I did my solid axle swap on my 4runner, I just used stock bump stop welded to the top of the ubolt flip kit plate haha.

Can I get away with no extended brake lines and my 5100's in the rear for right now until I upgrade?

Also, Can I reuse my stock factory shackle and eye bolts with these springs and the OME bushings? I'm assuming Yes.

Thanks all.

 

Cant tell ya on U bolt flip length. But I can take measurements on my standard setup EL095r pack if needed

Longer bumpstop not needed I rock the stock one with proper length 5125 Bilstein shocks (slightly longer than the stock length 5100's) and the travel works out great, more droop and not smashing the shock before bumpstop hits. Not sure if you are going to be able to use the stock bump on a ubolt flip kit though.

As far as extended brake lines I believe I added in a little 1 inch spacer between the axle and the brake line bracket where it goes from hard line to soft as well as bent the bracket to angle the hardlines up a bit. Stock softlines have plenty of free movement and dont get too tight on droop even with the longer 5125's

 

Thanks for this. U bolt flip kit isn't needed, I can run the standard ubolts. Can you measure yours to see the length for me? I got new ones when I did the single aal but can't remember if they were longer than stock. I plan to move to the longer 5125, guess I might as well just go ahead and do that now. Do you know the part number for yours? Was the only strange install issue the bottom mount being too narrow for the shock?
My old 4runner just had a bracket that moved the brake line bracket up so maybe i'll go that route. This truck wasn't built to flex that hard and most likely never will have to where it goes.

Thanks for all the info and assistance.

 

Im pretty sure it was 5125 part num 33-230337 ~ .5in of extra shock travel and ~1in longer collapsed and ~1.5in longer extended. With the extra thickness of the OME pack and the stock bumpstop measured out to ~ .5in of unused uptravel which is good as the stock bumpstop while rock hard will compress a bit. If you were to use the 5100's (which are a stock length shock) with the extra thickness of the OME pack you would be missing out on utilizing the shock travel as there would be a good chunk left on the table on compression and not much downtravel.

Yes the bottom shock eye mounting width on the axle is too narrow to fit the 5125 out of the box, but its only by a little bit. Easy enough to take the shock eye bushing sleeve of the 5125, grind it down a bit (~1/8th in) to fit in the stock axle hanger, then simply trim the rubber bushing to match on either side.

Im about to go to lunch so ill poke my head under my truck and confirm what I did for the brake line (honestly cant remember if i did a spacer+ slight bend of the stock bracket or just bend of the stock bracket) and get you a measurement of my U bolts with factory bump stop, EL095R (without an AAL) and the stock bottom u bolt axle bracket.

 

I can confirm the U-bolts with the wheelers kit you listed fit with plenty of thread to spare on the OME leaf packs, both heavy and medium duty. Had to cut em down a good inch.

 

awesome, thanks!

 

Very much appreciated.

 

Confirmed part number is proper for the 5125's

U bolt length. I have 7in square u bolts with rather long nuts (they are dobinsons U bolts). There is ~ 1/8-3/16ths of an inch of thread poking through the nuts on my EL095R pack with stock mounting hardware, stock bump stop + leaf liners on every leaf (would recommend leaf liners for no squeaks) + a thin 2degree wedge. The extra thickness of an AAL would make it to where the 7in bolts on my setup would be a smidge short and not utilize the full nut, but if they were a more normal sized nut they would probably be just fine. Needless to say if you went with the 7.75in option here you would be good if you wanted to stick with standard square u bolt vs the flip kit.

Brake line bracket. No spacer on mine (I think I had plans to make a spacer but never got around to it haha... maybe I should eh) But the bracket has been bent to face the hardlines straight parallel to the ground vs pointing down at the ground like stock. When I installed the 5125's (which will be the limiting factor for droop) fully drooped you are close to softlines being tight but not tight enough to cause concern of being pulled.

 

You are the man! Thank you!

 

Great info man. I have the 96r that has a leaf removed currently. After adding a topper and removing my aftermarket front bumper, I’ve gained about an inch in the front and lost about an inch in the rear. I’m about to put the leaf back in but I know I’m not going to be anywhere close to that 660lb load mark. So I know my 5100s will be pushing its max extended length and leave me very little room for travel. You said that the 5125 would be the limiting factor to droop. Just curious if you could expand on that. Also, you said no concerns with brake lines, was curious if you could share a pic of what you did for your bracket. Thanks in advance sir!

 

Limiting factor of droop: If the shocks (either 5100's or 5125's) were not attached to the axle the natural arch of the OME springs droop out (extend down) quite a bit further than the shocks would allow. The shocks become the limiting factor for droop when attached, 5100's more so than the part number 5125 mentioned above.

Rear brake lines. This is really personal preference, theres zero issue with going extended brake lines but when we are talking ~ 1in extra of droop over stock its easy to make the stock lines and stock bracket work. That stated, working on the rear axle when removing the rear shocks / replacing leafs etc, undoing the brake line bracket from the axle allows the hardlines to flex up a bit and not stress the soft lines. My running solution was to bend the stock bracket to point the lines more level from their stock downward point so the softlines wernt as tight at full droop. I can definitely get some pics when I get home from work.
