Budget Boost vs. "normal" suspension lift

This is probably something someone better at the search function could find, but I haven't really been able to find what I'm looking for.

I have a 1997 Wrangler 4.0 5 speed. All factory. I want a lift for mild off-road use. I've been looking at the Rubicon Express 2" budget boost and an OME 2.5" suspension lift. I realize price wise those two are on opposite ends of the spectrum.

I also understand the parts difference in the kits (and thus the price difference), but beyond that what makes someone go one direction over the other? Outside of money, is there a situation where the budget boost is a better choice than the OME (or like) kit?

I'm assuming the overall ride quality will be better with the OME, but that is purely an assumption. Is the OME more reliable? What else do you consider when choosing between the two types of lifts?


Thank you.

Praying there isn't a thread just like this that I missed

Budget boosts have no advantages over a true suspension lift...it is basically a prettier alternative to a body lift. Well that and it lifts the frame and everything like a suspension lift does compared to a body lift which only lifts the body...but you still gain no additional travel in the suspension system.

If you can afford a suspension lift, definitely go that route.

Thats basically it...budget boosts wont gain you anything other than height. You wont gain any more travel because for every inch you add to the top of your spring (with the spacer) you will have to add an inch of bumpstop extension. Suspension lift is the better alternative if you can swing the cost.

the suspension lift is always better than a BB, and the reasons why get into the suspension geometry of the TJ's solid axles.

with a BB, you're basically pushing the stock spring down, and reducing the space it has to compress into at full suspension compression. You'll need to add that space back in with bumpstop extensions to prevent something call coil bind, which will damage your coils. You'll also need new shocks.

with a suspension lift, you install new springs. If you buy a quality spring, like the OME you've referenced in your post, the spring is much longer than stock and may have the same spring rate or even a higher rate. The higher spring rate compensates for added weight...like bumpers, winches, skid plates, etc. The longer spring not only provides the lift, but it also has a very important function when off-road. The lift kit includes shocks that allow the axle to travel more through the suspenion cycle - sometimes refered to as flex. When flexing, the longer spring allows you to retain better traction off-road because the spring doesn't come unseated. If the spring becomes loose and unseated, it stops pushing downward force on the tire...so the only thing giving traction is the weight of half the axle and that one side tire.

a spring lift often allows more uptravel too. your suspension cycle includes uptravel and downtravel. uptravel is the amount the axle can move upward to full bump from ride height. downtravel is the mount it can move downward from ride height. uptravel is half the component of your suspension.

Here's an example: In the rear of the TJ, if you install a BB, you need 2" bumpstop extensions to match the BB height of 2". You gain no uptravel over stock. However, if you install a 2" lift like OME, you only need 1.25-1.3" rear bumpstop extensions to prevent the shocks from bottoming out. You actually gain 3/4" uptravel over stock.

The gain in uptravel is one component of a better ride - both on road and off. Another major component is the shocks - quality shocks like the OME N66 and N67 will provide an great ride on road and off.

The only time I'd recommend a BB is if you're being cheap (budget) and just want a slightly taller stance. Either lift, you're still limited to a 31" tire unless you adjust the bumpstops more and/or a body lift and/or a highline fender modification. not to say 31's are bad, but people seem to want bigger tires because they think that means something special...but 31" tires and a good suspension system will get you pretty darn far on most trails.

That all makes good sense. Thank you for the great replies.


I guess my second question on going with a suspension lift---does it make better sense to buy a kit (all in one), or to piece one together? I'm concerned more about quality than cost. I absolutely hate when something fails.

To the OP, banace your realastic needs with the amount of money you want to spend. There are alternatives between a BB and OME. Consider BDS 2" and people are having positive reviews of Zone.

I understand I was at opposite ends of the price spectrum. I was more trying to understand the budget boost and why you would use one. The lack of extension is something I had not considered, and that alone is reason for me to pass on the budget boost.

Now I'm looking at lifts. Like I say above, my main concern is reliability. I want to buy something once. Not buy something that is lower quality and lower priced, only to have to replace it 3 times.

Then OME is a great place to start.

Well a 2-2.5" such as what you are considering does not consist of many parts. Springs and shocks are the main things and there is not too much that will go wrong. 4" and above lifts need more parts. Do a search on BDS or OME and you will find no complaints. Zone is relatively new. Rough Coutry has sold a lot of kits and has a lower cost 2.5 but the older shocks have been hit or mis and spring sag apparently does occur.

The problem with kits is they aren't complete. Figure 50% to 95% complete, depending which one you buy.

OME's as it comes is in the 50% range. It includes rear bumpstops, springs, shocks and a rear relocation bracket. The rear bumpstops aren't long enough...they give you 0.8" (20mm) extensions, but you need 1.3"...and longer M10 bolts. On the other end of the spectrum, you've got the 3" Savvy/Currie...which is quite complete.

I'm running an OME "hybrid" suspension.....Rokmen control arms, tummy tuck, CV shaft, 1.25" BL, OME #934 front springs, #949 rear springs, the relocation bracket, 1.375" bumpstop extensions in front, and 1.3" rear bumpstop extensions. Both front and rear track bars are custom because nothing on the market right now fits without more bumpstop extension than i'm running. It fits 33s, has more uptravel than stock and is very reliable.

Look the build over and let me know if you have any questions
