Drive shaft sale is suspended, for now at least.

it's a long story....but, anyway, i have two 4" aluminum drive shafts that were built locally that i'm putting up for sale

shaft A

4" shaft with 1310x1330 performance dynamics conversion ujoints. this is the first shaft that i bought which was built locally. when i originally bought this shaft, it had greasable light duty joints. i ran it probably 3 years. it didn't vibrate after having it balanced by driveshaft specialists (after the original builder did an insufficient job of balancing). i used this shaft as said for probably 3 years. after i started launching on slicks at the strip, i decided to upgrade to the better performance dynamic ujoints. after the upgrade and rebalance, the shaft picked up a slight vibe above 80mph..this is with 4.56 gears..up to about 115. at about 120, this shaft on my car vibrates at a rate which you probably wouldn't want to drive at for long. my desire is to do the texas mile, so i looked for a second drive shaft to fab up, which leads us to drive shaft B

shaft B

4" shaft. this shaft i purchased brand new from larry's drive shaft on ebay. i took it to driveshaft specialists (thrash) and had it shortened and rebalanced. it has straight 1330 spicer ujoints. this shaft acts exactly as drive shaft A does, slight vibe over 80 to 110, but not really drive-able for long at 120 or above. not really a surprise that they act the same as they were balanced by the same guy. i consider shaft B to be the better of the 2 drive shafts, at least in terms of strength.

i spoke with DSS about these drive shafts, and they will balance any shaft on their ultra high speed balancer for $150 plus shipping. my decision was instead of spending more money on either of these two shafts to go ahead and buy a shaft guaranteed not to vibrate so i can run the texas mile with confidence. my belief is that either of these two shafts, balanced on their ultra high speed machine, will produce a drive shaft that would do pretty well in terms of not vibrating, but i can't guarantee it.

so, i'm selling them cheap

shaft A, $125 plus shipping
shaft B, $150 plus shipping

both of these shafts will come with the pinion flange to make them work on your 8.8 mustang. some may be concerned about switching flanges out. i can only say, i've swapped mine numerous times without incident, despite what all the experts say about having a shop do the work

pm me if you're interested. i'm not interested in OBO at this point.

okay, it seems more information is needed. prospective buyers for now assume shipping may run between $25 to $50. to the lower 48. i haven't boxed them up and measured them yet for quotes at the ups store, so make your own assumptions about shipping

as far as mods are concerned to make these shafts fit....on a lowered car (pro kit on mine) i had to relocate the e brake bracket. there are a couple of humps in the tunnel that may need to be dinged a little with a hammer depending on how low your car is, but it's not a lot of work.

also of course, if you have the stock cv flange, it will have to be changed. take off the oem shaft, us a harmonic balance puller if you have one, and pull that one off. have your new flange standing buy and spin it back on with an impact if you have one. i torque mine to about 140lbs after installing the new flange, and it's never created a problem. i've done this several times while swapping between the oem shaft and the aluminum shafts while having them balanced.

i'll ask the experts that say this shouldn't be done to not post about that in this thread. let the buyer(s) decide how or who will swap flanges.
