I found a sweet deal on a 8" rize lift with with a set of rims w/ 40"x12.5xR22 rims / tires. I'm seriously thinking about getting it, but my commute just doubled from 40 miles round trip a day to 88 miles round trip (or even more) a day. I just want to get an idea of what kinda of mpg I can expect w/ 8" and larger tires. If you've got 37's / 38's please chime in.

I have an '04 screw 4x4 with the 5.4l.


It's between getting this lift, and possibly setting it aside for a while and not putting it on, OR putting it on right away, OR getting a 4 wheeler... I HATE BEING INDECISIVE!!!

also; right now, the PO put on a "budget lift" which is like longer coils up front -- not coil spacers, but actual longer coils-- and aal's in the rear... the ride sucks, thats why I'd like to go with the rize kit. But mind you this, I also pull my mud truck from time to time. It's a '92 jeep on 2.5 ton's with a sbc.

 

if you havent re gear you need too bc with stock 3.73 trying to spin those tires will eat up your tranny and even worse gas mileage but i had 37s on my with 3.73s for awhile an only got 11mpg but thats bc my exhaust and cut out all four cats but your looking anywhere from 12-14 mayb and also if im not mistaken you wont be able to fit 40s with that 8inch rize

 

the guy has it on his truck now with the 8" kit, the 2" coil spacers, and the 40's and it doesnt rub.

Right now, I get 14-16 with the "budget lift" and the 31's that are on my truck with the 3.73's.

The guy says he has to drive with OD on or the rpms get WAY UP there, he says, thats my only hesitation about pulling a trialer - but he pulls a sprint car trailer with his ~ about the same weight as my jeep and trailer.

 

ok well that makes more sense bc then your up to 10inches of lift so yeah you can fit those then if he is....and i had 35s on my truck and got 13.5-14mpg and with 37s got 11-12mpg and im telling you right now your gonna have to re gear bc it will take a lot of pressure of your tranny

 

i was really thinking about getting it all and then selling the rims and tires. They're 22" KMC's with 40x15.5 (not 12.5 like I thought) Toyo open country MT's.

I'd like to get 37's or 38's. A buddy of mine has 38's on his 250 and they look good... I think the 40's on the 150 look too big and like you said, I would have to regear or have NO ACCELERATION at all..

 

I would say don't do it you have a mud truck. Don't put 40's on F150 just put 35" and nice wheels and then you can still pull your jeep

 

Even if you do regear you'll never make up the power loss, and will loose you **** on mileage..

I'd say w/ 37's to 40's around 8mpg if your lucky
There ar3 several members on here that will readily admit that their trucks w/ Rize don't even pull 8mpg regularly....

If you have to worry about the mileage it may not be for you....
Just saying............

Either way save about 500-700 for install since a hsop won't make any money on the lift, labor will likely be higher....

And around 1500 or so for quality gears...

Good luck

 

I got 13.5 mpg with my Rize 8" and 37x13.50s. I'd stick with 37s or 38s and still regear, especially considering you're going to be towing.

 

12 in town (when ******* on it around 11), 14.5 avg highway.. on 38/15.50s with 4.56 gears.

I'd stick with 38s personally, unless you're doing a body lift too. Good luck!

 

I get about 10-11 in town. I went to dallas this last weekend and 15mpg was the best i coiuld pull highway... Id agree with everyone else just do 37's if your going to leave it at 8" or go with 38's if your keeping it at 10" of lift. I pull trailers occasionally and have no problems but gas wont last long with a lift and trailer behind you...

as thump said, you should regear. Ive got 4.88's and love them!

 

How do you guys get such good mileage

I got a stock 2500 GMC Seirra 8.1 liter...and get 10mpgs when babying it.
My old Hummer h2--on 37x13.50 Toyos I got sub 8mpg.

Sh+t I want good mileage tooooooo.

 

to the OP:

I would suggest keeping your truck as is, and putting more money into the Heep. You already got a mud truck, why two ? With gas prices as is I wouldn't suggest the mod. Plus, towing that much weight, with such a high lift and large tires... your gunna be putting some serious wear and tear on your truck.

I would personally say, either put the money into the Heep, or buy a quad to mess around with. Quad is something easy, and you can throw it in the bed of the truck and go. The my 2 cents.

So, you build that Jeep yourself ? Or buy it ? You need to take it outta the goo, and come play on some rocks !

 

man, you guys are a great pursuasive tool. As far as lifting the 150 to mud... never. I hate the IFS too much to be replacing the cv shafts and boots as they tear - straight axle is the way to go. So IF I lifted it, it would just be a street queen to look good in going to the store, to the bar, and pulling the heep.

I built the heep. I used to drive it to work when I blew the rear axle as it was sitting on 33's. Parked it in the garage and rode the cruiser to work for a few weeks until I bought my 150. Found a great deal on a set of rockwells, decided to put the jeep on them. Swapped out the 6 cyl HO for a SBC 350 mated to a TH400 with an NP200 transfercase. That picture, I have 44" boggers on it but now I have 14.9x24" tractor tires on it ~49" tall. As far as playing in the rocks and not in the goo... I don't flex that well with 12" leaf springs all around. Maybe when I rebuilt it with coilovers and 4 link it I'll hit the rocks.

Thanks for all your insights -- so maybe I should just go with like a 6" lift and some nice rims w/ 35"s?

 

Nice ! Sounds like a damn decent little Jeep ya got going on.How do ya like the NP200 ? Not a common T-case. I know your a mud guy, but ever think about a small stretch and Np 205/203 doubler ? And you wana go coils huh? Maybe just airshocks and links ? A little cheaper. Just a couple thoughts. Would be pretty sweet, IMO. I'm a samurai guy myself, but I got a little respect left for those Heeps. We squeeze through chit the rest can't crawl over !

Anyways, the last part sounds like your best bet. trust me, you'll be saving a ton of money, a ton of wear and tear on it, and you'll still love the stance of the 6" lift. I know I am still very happy with mine.

 

yea, the heep is pretty stout. I'm running an np200, like a lot of people in the mud arena, due to the ability to clock it pretty much vertically and get about a 9" drop out of the front and rear output shafts. The np200 has i input, 3 outputs, 1 inline w/ the input and 2 offset. This helps with drive shaft angles as does the top loader axles. I couldn't do a doubler, right now, I don't even have a jack shaft between the th400 (2wd) and the np200 - it's ujoint to ujoint. My rear shaft is 1" long. ( the actual drive shaft material, not including the yokes and slip. overall, my whole rear shaft extended is about 13" ) So I don't have enough room to add another tcase.


B.O.T.

I'm actually thinking about buying the lift and rims, and putting the 8" lift on with 35's and selling the coil spacers and the rims and tires.
Anyone know anyone in the market for 2" coil spacers or 22" KMC's with 40" 15.5" Toyo open country MT's?

Believe me, if i could sell the rims and tires - the lift is DEFINATELY WORTH buying ~and I'd put it on myself, so I wouldn't be paying for install... ... directions?? how need directions when you have a blowtorch and welder.. ha ha ha.
