Lift / Tire and Wheel thoughts

But these springs didn't lift my Jeep as much as (or more than) advertised. :)

Because your jeep weighs more than the average bear. My 933/942's raised my jeep exactly 2.5" with a M8000/minimalist bumper up front, and light rear bumper/31" spare, with no back seat, and the hard top.

Sometimes I wonder where I would be now on my build if I had never needed to figure out how to get the back end of my first lift high enough.

I bet you could figure it out. Why are you still running the equivalent of a 33” tire on a 4 + 1.25 Lift?

0-60 in 18 sec. That’s about the time I got when I clocked it. LOL
 
Ok so I don’t want I hijack the thread.

If your going 2” but only having a 7” wheel what size would you guys be recommending?

That OME but I'm not so sure about that specific model of shock. I ran OME NItrochargers for years and they were great but that model has been discontinued and from what I have read, their later model shocks have gotten a lot stiffer riding.

OK, pretty convinced to go with the OME lift kit. But, one more question...light or heavy? I have no intention of getting a winch and I have a soft top with intention of riding w/out doors most of time ( this is not my daily driver). I’m more interested in a comfortable ride so thinking on the light-stock version.

Ride quality relates to shocks and tire pressure, not springs. Get the right shocks and you will have a comfortable ride

Edit: what the springs do is hold the weight of the Jeep up. What the shocks do is restore the Jeep to ride height after compression so you don’t go bouncing down the road on your springs. Tire pressure on 31’s should be about 28, on 33’s about 26

Check out the link in my signature for photos. I am running the light duty springs. They are fine, even with the hard top.

At this point I would recommend calling Dirk at DPG. If you purchase the kit through him, it will be close to the same price as you buying from various vendors, unless you find some sort of crazy memorial day sale. With Dirk, he will walk you through the part numbers you need, and will chuckle at LD or HD, he will make sure you get what you want, and you will have full support from Dirk for any install questions. If there are any issues Dirk will happily talk to you until your issues/concerns are resolved. Amazon, Quadratec and those types of Sellers provide zero support.

Talking to Dirk is a good idea. He will ask questions about how your Jeep is built and use that to estimate it's weight. From there he can pick and choose which springs are best for what you want to achieve.

@Alvin A
I do agree that talk to Dirk is a good idea but for what you looking for, is no need to go that direction. As @glwood mention the light duty springs will do fine, is on the shock and the tire as well where you need to focus to get the ride quality you are looking for.
We pair the OME light duty springs with Blistein shocks out a Amazon ending up on a good combo for a Jeep that has winch and and a aftermarket tire carrier , but wasn't until the addition of the 32x11.50r15 BFG KO2 that we do notice the ride quality improvement.

The OME Nitro charger are not bad shock, i do run the sames on my LJ and I can tell they are the correct for the TJ's.

Regarding vehicle weight:

Rather than estimate the weight, visit your closest CAT scale and get your jeep weighed with a full tank of gas, all of your trail and camping gear, and you. You don't need "certified weight" so it should only cost a few dollars and it only takes a few minutes. You might be surprised by the results. https://catscale.com/cat-scale-locator/

Before you ask what my jeep weighs, I must confess that I weighed my last jeep and my "other 4x4" that I use for extended overlanding trips, but I have yet to weigh my current jeep since I purchased it last summer. When I do, which is likely to be in the next week or two, I will get it weighed both loaded and empty so I can make educated decisions rather than guess. I have known too many jeepers and other offroaders over the years who have guessed wrong despite their best intentions and made expensive mistakes that could have been avoided by knowing the actual weight.

Exactly, don't select springs thinking they're what give you the ride quality you want. It is the shocks that do that, together with inflating the tires to the appropriate pressure. The springs support the weight, the shocks are what control the quality of the ride... followed to a lesser extent tire pressure :)

I do agree with your point and we should not guess our rigs weight, but that is why I recommend the OP to listen this thread suggestions that comes from proved product end users than call Dirk that anyway he will be guessing his rig weight to accurate sell the product.

J - newbie here. I hope this is the right thread, so much in the way of tire/ ride info. 2008 TJ 4" lift. very harsh ride. replacing shocks with your suggestion Rancho's 5000x. My son wants 15" rims with 33" tire. he is 90% road and 10% muddy field driving. what is the sensible formula? Of course he wants it to look like an off roader.
thanks

If you have not spoken with Dirk then you should not make comments like this as you are 100% off base. Experience is worth a whole heck of lot more than you are valuing it to be. Dirk takes the time to listen to what you are putting on your rig and his experience is what we all lack, except Jerry and Blaine and a couple others.

I used the forums to narrow down what I wanted, then found an expert in that brand and the rest is history. I have read numerous threads of members buying suspension parts from Amazon and then asking why their jeep is not level, or some other issue. Dirk is there to also help you through the install, and gives you a cheat sheet with tips and directions.

Sorry, don't mean to attack you, but Dirk is tremendous and you are shorting him.

Is 2008 the correct year? TJs ended in 2006.

After replacing my RMS on my ‘06 TJ this weekend, my next upgrade will be a suspension lift with new wheels and tires. Thinking on the Skyjacker 2 1/2” lift with M95 performance shocks, then some Mickey Thompson Baja ATZ P3 tires (P265/75R16) mounted on Quadratec Rubicon Xtreme wheels in black...Thoughts ?
Click to expand...

I Feel like it would be nice. I just ordered the 2.5 skyjacker coils with the RS5000x Rancho shocks and Im having a good feeling about the combo. I plan on upgrading from bald 31s to meaty 32s sometime this year I think it'll be an realistic combo especially bc I don't want to push my Stock D30s/35s with my 4 banger and don't plan on going any bigger until more engine upgrades

A truck scale won't tell you the sprung weight which is what it needed to calculate a spring's lift height. First you need the front and rear total weights on the wheels. Then the weights of the tires, wheels, axles, half the springs, shocks, links, etc all need to be subtracted from the total weight.

I was able to very closely reverse calculate my sprung weights from my first set on OME springs because their rates are published. That's the nice thing about linear rate springs.
