    IRS Brace

    Who has one and has it aided the IRS in keeping the diff. from leaking?

    Mine was perfectly fine, even with 80+ passes on them. Even with the gear swap & 20 runs on them NO PEE!!!

    Then I took the sway bar loose and with better 60', I noticed the scent of diff fluid & saw the evidence last night of the PEE!

    Not much, but still noticeable!

    I have the Billetflow piece. I bought it to keep the cover from breaking. Keeping it from leaking is a nice bonus though. Lots of these things leak just ever so little. Once you see it on the ground it's time to reseal it.

    So you didn't go to the Solid Axle Camp?

    OK, so the diff. brace will help then? Not to worried about blowing the cover or the diff....

    My understanding is that the front of the pumpkin is fairly firm, but the rear tends to move around alot under extreme stress and the way that stupid FORD designed the back of the IRS to the Chassis allows all that flex between the diff cover & the pumpkin...not sure how the brace holds it in place, but calling Leathal Performance for the Billetflow Brace now.

    Tetge got his installed yesturday & the shop says it is a far better piece then Brakelate who got a good deal on a Steeda one.

    I have the Steeda one and it has an extra triangulated support on it. Look at a picture of each and you will see it. It was a bitch to put on, even having a rack it still sucked!

    Hum...Shop says that the Billetflow one went on pretty easily.

    I got to see Brakelates brace last night....although not on a lift, I couldnt tell any difference or see the entire picture between the two.

    I just dont want the car to PEE anymore!

    I'm wondering if the brace transfers more of the vibe noise from the 4.10's to the body of the car?

    Brace looked pretty stout, but the gears make the whole back half of the body drum, not like my '01 where the vibes from the 4.30's were basically isolated.

    Crossing my fingers and hoping mine dosn't start leaking.

    I would say no since it only bolts to the rear. There is no connection to the body, so the noise should remain the same.
