throttle body spacer

it claims to increase power and gas mileage, is there any truth to this?

IMO - Don't waste your money. If you are running a carb and have a heating problem and your 1/4 mile racing, a phenolic spacer does wonders to minimize fuel boiling.

They can make you're jeep whistle and if you practice, you can get it to hum a tune with the skinny pedal.

Other than that, spend that $$$ on other stuff.

The stock TB works just fine for FI. The chips are a waste of $$ too.

X4 on the above, TB spacer is a waste of $$$. Same on a bigger throttle body. Someone gave me a 62mm throttle body and it made no difference I could detect. I do have a TB spacer in my junk box if anyone needs a paperweight.

can we make a sticky topic with all the junk NOT to waste money on for your jeep? it'd save us 10 new topics a day.. and then people wouldnt even have to use the search feature that they fail to do

just giving you a rough time TF nothing personal

Spend $20 on a Chilton or Hayne's manual and put it next to the crapper. Everytime you contribute, you'll gain more knowledge and consolidate your time.

heh ive had a bad couple of days

like i said.. im just giving you a rough time.. this question seems to get asked almost daily..

most other jeep forums have a sticky with all the info on a stock jeep ect.. i would love to see some of that on here.. this forum is FULL of GREAT information if you search for it.. we got some VERY smart guys on this board.. i came on hardly knowing anything about jeeps minus just the basics.. and since then ive torn my jeep apart a few times.. axle swaps, swapping out hubs and axle shafts.. lifting my jeep a few times.. helping out guys with their jeeps.. and even a few cool mods like being able to keep my stock foglights on with my brights..

i know.. i didnt mean to scare him from asking questions.. we will ALWAYS be here to help you out TJ.. no matter how dumb the questions can be jk.. i use to ask dumb questions too when i first got one..

if you ever do have a question to ask, more than likely some has asked it before you, probably more than once.. the search feature on the forum is a GREAT tool for finding information.. sometimes you can find stuff that way faster than starting a new topic and asking yourself..

check your stock gear ratio.. its on your diff cover..

i ran 33s with 3.07s just fine.. would top out at 60-65 mph on the highway though.. yes it was a little sluggish from my 31s but i didnt notice a drastic change..

my 3.73s in my new axles DEFINITLY help out though.. i can reach a greater max speed and its not AS sluggish..

give us some more info on your rig.. 4 banger or i6, auto or manual, ect.. and we can help you out..

heck if you have 3.07s sometimes its cheaper to find doner axles from lets say a 4banger.. which will have 4.10s.. i know it was around 700 bucks PER axle to get my old ones regeared in town.. which is why i waited to get a hp30/d44 to swap out to change my gear ratios.. still not what i wanted but for the same price it would cost me to regear my old axles.. i was able to step up 2 gear sets and get heavy duty axles

when you choose to regear.. dont go any less than 4.56s

4.88s would be ideal then you would have plenty of room if you ever decide to run 35s

Those numbers (like 4.56 and 4.88) are the ratios of the gears inside your axles, which are called the ring & pinion gears... the main gears that convert the rotation of the driveshaft to the sideways motion of the axles that spin the tires.

4.56 and 4.88 are actually 1:4.56 and 1:4.88 which means the driveshaft and engine turns 4.56 or 4.88 times for every single rotation of the axle (tire). The lower the ratio (i.e. 4.88 is a lower ratio than 4.56 is), the more engine rpms there are at a given speed.

So for a small tire like a 29" which takes less power to turn, you might run a 3.07 axle ratio but for a bigger tire like a 35" diameter tire, you'd want a lower axle ratio like 4.88 (1:4.88) which would produce higher engine rpms to produce more power needed to turn the bigger tire. Bigger tires cause the engine to run at lower rpms which usually means less power, so you change the axle ratios (by swapping in different ratio ring & pinion gears) to raise the engine rpms back up to where the engine can then again produce the power needed to turn the bigger tires.

Make sense?

Look for a small metal tag held between two bolts at the cover's 9 o'clock position. Take a flashlight and a rag to wipe it off with, the ratio will be embossed into that vertically oriented tag. It will say either "3 07" or "3 73" which is your axle's ratio. The front and rear axles are usually .01 off from each other so it may in fact say "3 08" or "3 74" depending on which axle you look at

Better yet, go with the official Factory Service Manual for your year and model Jeep that gives specific and accurate information for your particular Jeep. I'm NO fan of Chilton's or Haynes' manuals because they try to cover too many model years of Jeeps and are thus not all that specific on any particular model year. Too many photos that say "should look like this"... I want specific information that I know to be accurate, not generalized statements that attempt to cover too many model years that change from year to year.

Much of my bathroom's floorspace is devoted to various technical manuals and 4x4 magazines... much to my wife's total inability to understand.
