Ok so im looking to get a jeep with the 44/60 swap...and the guy said the brakes are weak...said that the stock brake booster wasn't strong enough for the bigger axles...also said he thought you could swap a booster from a 70's ford into it...just want to get some info on this and what exactly i need to do...thanks.

I know a kid on this very forum who swapped fullwidth 44 and 60 axles into his XJ. He put a master cylinder out of a 2001 1 ton Dodge truck into his Jeep and the brakes work like a champ!! You buddy is absolutely right. The OEM master cylinder in an XJ doesn't have the fluid volume for the bigger brakes on the bigger axles.

Ya i also read that too...you have any idea if its just a simple bolt on...or do i have to modify anything?

BuckB91XJ

Yes the master cylinder out of the 1 ton Dodge does bolt directly in but you will have to make a spacer cuz your Jeeps push rod is a little short.

PM 98CherokeeSport if you have any other questions. He has gone through all the trials and tribulations of putting 1 ton axles in an XJ.

Alright sweet thanks.

What MC you want will depend on the year of your XJ. The earlier models have a different booster than the newer XJs. If you have an earlier XJ you can swap on a later booster or thier are MCs that will bolt on to the earlier booster.

I used the dodge 1 ton MC on my 98. You will need to extend the pushrod, this thread shows you how.

Thanks a ton...that helped a lot...also said you could use a 78 f250 MC...i'll see whats cheaper and easier to find at the local u-pull-it...O and its a 99 XJ.

I would just go to Autozone and buy this, its what i used. Should bolt on a 99 just the same, not making any guarantees though.

Not sure if I just got lucky but I'm running a stock ABS MC with the fuses out and 38s on my 44/60 combo and it stops on a dime.

Sean883

I'm running 37's and 4.10s, but i just ordered 5.38s and an ARB for the front.

I've heard lots of people say that. My stock MC stopped me just fine but I didn't like how soft the pedal felt.
