Anyone swap rear springs? (1 Viewer)

Thanks @mcgaskins

Yes, I have been happy w the STT Pros. They hum a little, but not excessive. Can still hold normal conversation and whatever noise is there fades to white noise pretty quickly.

Went out to the local preserve and snapped some photos. So as to stay on point relative to the original post’s intention, will include pics of the entire truck below and add some if the other pics on the rubs to the wheel spacer thread.

This is the OME 2702/2721 combo w 15mm packers. Very pleased with it.

What are the current measurements from hub to fender with this setup?

Where did you get the 15mm packers for the rear?

 

[Mineral]

15mm packer = 10 mm packer + 5 mm packer. Supposedly there’s a limit to how high one “should” stack them. Off top of my head, I recall 15mm was on the conservative end.

Looks like it settled at a 1.25” rake.

Front center hub to fender lip is ~21.25”.
Rear center hub to fender lip is ~22.5”.

Give or take on the above. It’s hard holding the measuring tape, the phone, and staying perfectly at hub center. (I did first measure sans phone, so knew the targets.)

Also, provided below are floor to fender lip heights. On 285/65R18 STT Pros w ~8k miles.

Front: ~37.5”
Rear: ~38.75”

Feel free to tell me I’m measuring wrong, if that’s indeed the case.

While taking the below pics, realized that am tossing road grim up against the outside of the front fender lips and chipping the paint here and there - due to the wide tires and spidertrax spacers not the lift, of course. Made me chuckle enough to share the observation. This setup, maybe this rig for that matter, might not be the best option if I obsessed on perfect paint.

There’s no guarantee the front and rear fender heights are identical. I measure the height to the bottom of the running boards or sliders, since those should be parallel to the road if you are perfectly level. They’re inboard to the wheelbase so just note that 1/2” difference front to rear is probably closer to 3/4” from hub to hub.

Hi guys. The friend of mine told me about OME suspension for my LC 200 and I decided to try it, but here in Moscow we don't have enough experience with OME to make the right choice, so I'll appreciate any help. I have a diesel model with additional 40 litters tank, 60-80 kg active vacation, no winch on front or back, stock bumpers and 285/65 r18 LT tyres on light Rays rims. I do not need leveling suspension, lift not more then 1 inch, but at the same time I dont like when rear is much higher then front. So as far as I look through what you wrote here I decided to order the next kit and really need your approval before I pay=)
Here we are:
Front: 2700 + 91005 SPORT
Rear: 2721 + 61029 SPORT
Would it be good for me?

 

[linuxgod]

I think OME tend to run taller than listed. You may want to look at Tough Dog or another option with less stated lift (I got about 1" in the rear and 1.5" in the front with the Tough Dog standard setup).

Your sub tank holds 40L which is 34kg or about 10gal/75#, I believe. I would not upgrade the suspension since the sub tank and fuel is <100kg... standard duty springs should be fine

I would like to use tough dog kit, TD much cheaper here, but the problem is that TD shocks start leaking if it used at low temperature. TD kit good for summer, but shocks rarely survive after winter snow roads.

 

[linuxgod]

Mine have survived 2 winters in Chicago, with snow, salt, and temps below -20F. No issues, minimal rust except the 4 bolts at the top of the front struts

Guys, dealer of Pedders just opened office here and made me a good offer for Pedders kit against OME kit. So I have to choose OME or Pedders.

OME Kit:
Front: 2700 + 91005 SPORT
Rear: 2721 + 61029 SPORT
VS
Pedders kit:
Front: 807109 L/R
Rear springs: 270096
Rear shocks: 9502 (Foam Cell)

What do you think about it? Any advice would be good. Thanks in advance

By way of follow-up, the 2702/2721 spring setup has served well for the last year and a half or so.

With the MT4x4 bumper now installed, the RLC rear bumper and BB sliders coming soon, am provisioning to swap out the front and rear springs for a 2703/2724 setup.

2703s were pretty straight-forward - maintain the 2" front lift with stiffer springs.

2724 was a bit more challenging to decide upon. After talking with a highly respected fellow mudder about his experience running bumpers, sliders, and roof rack, he swapped the 2723 for 2724 when adding the long range tank. As a roof rack and aux tank is on the to-do list, I'd rather swap the springs once rather than twice. So, am thinking 2703/2724 is the way to go.

Btw, talking w/ @sleeoffroad today, the 61029 shocks (vs firmer valved 61030) will work just fine paired with 2723 or 2724 rear springs - despite "recommendation" otherwise on other sites. In fact, Slee mentioned they typically pair 2723/2724 w/ 61029 anyhow.

So, if anyone is looking for 2702/2721 springs, pm me and we can work something out.

Swapped out the 2702/2721 for 2703/2724. Kept the packers in and very pleased w the result.

Wish I’d have done this setup from the get go.

Result is ~+2” front and rear. Ride is definitely firmer, but not harsh. I like it. My 3 year and 5 year old aren’t jolted in the 3rd row.

When asked if the cruiser looks taller, my 3 year daughter said w serious awe in her eyes, “no daddy, it’s BIGGER - way bigger now.”

Now those 33s are just looking a little undersized. And there’s a slight kdss lean that needs correction. Always something...

Great intel here, but got a bit of a tired head after reading it all.

I too have a set of BP51 and I'd like to know if anyone has found a good set up for a fully loaded rig, with F/R bumpers, winch, RTT, awning, drawers... Pretty much a 'Big Girl' Edition.

2724s if you like it firmer or plan to add an aux tank in the future. 2723s with maybe a 10mm spacer is you like it softer and daily it on poor roads, think Chicago roads.

Copy and thank you for simplifying the math! aux tank is in my near future so 2724 it is. How about the front?

I read above that you have BP51s, if that is still the case, the front has a coil that you will not switch out. Set preload to give you the rake you like. That is a little more personal preference of how much preload. Some guys want more, which gives a more leveled look, but then they get closer to a saggin wagon look if they load out the back end. Some guys want less preload, as they want to be able to slam more weight on the back end, and not have the back look like it is struggling.

Got it. Much appreciated.

I will be replacing my 2722’s with 2723’s in the coming weeks and I have some questions before diving into this.

1. I have a 40 gallon LRA and dissent rear bumper. Where should I plan on putting the jack stands? It’s pretty tight behind the rear wheels.

2. Current springs have airbags which I didn’t install (I actually didn’t install anything, had it built.) How much slack in the airline can I expect or is it easier to leave line attached and just work bag out of spring without disconnecting air line?

3. How should I determine if I need rear spacer? I do not believe there is one, I have been keeping a spreadsheet of fender measurements… they are very dependent on how I load out. Should I use a spacer or utilize the airbags to level things out?

4. Remove everything and use up LRA gas before doing this or just jack it up and go?

I’m hoping moving up in spring rate will solve a tire cupping issue, reduce my psi in airbags (60psi at times), and help with slight floating front end while towing on interstate at speed. Typical rear end weight can run 5300 pounds and bags at psi at 60 keep fender measurements level. This is while towing, tongue weight is 375. We pull the camper off road a lot so I’m hoping not to give up too much with the stiffer springs but I feel like I just don’t have enough spring rate given the weight I’m running.

2. If you’re removing the springs and there is some airline slack already you may be able to push down on the fitting in the top of the as and pull the airline out. That said I’ve tried that twice and both times the fitting was stuck and I ended up cutting the airline at the bag and using new airbags. The bags stretch after a while and will be REALLY hard to remove in my experience.

3. Measure center (or top) of the rear axle hub to the bottom of the fender lip above on both sides. However much you’re different is more or less how much you need. I.e. if you’re off by an inch, try to find a 20mm spacer or a pair of 10mm ones. You can stack them but there is a limit before I think ARB would consider it too many. Note that the FSM says if you’re within 15mm (6/10”) left to ride you’re within spec (though I got within 1/8” IIRC)

2. Thanks for this information, I had not even considered bag stretch. It’s probably wise to have new bags ready to install before starting this project.

3. Take these measurements while loaded for a trip, I assume. This is not a daily driver so there is not much difference in gear that it carries. I have a 10mm and 5mm spacer so between these I should be able to get it in spec.

Thanks.
