Well there are two mounts for the rear diff.... a rear mount, and a front mount, so it can definitely be confusing. The rear diff REAR mount is the one that can fail and cause axels to snap. SU and CPE are the only companies that make the rear diff "rear" mount. Most people just refer to this as the "rear diff mount." Turbine Tech makes the rear diff FRONT mount, which you don't need (and they don't make a rear diff rear mount afaik).Alright, I know the mounts for the differential are bad, but if I had to choose one mount what is my best bet? I don't drag or track race.
Turbine Tech Diff Mount vs SU StiffDiff Mount

Just put in the CPE diff mount after breaking the stock and a SU mount. no problems yet, good luck getting a SU mount been out of stock for a while.
And the SU mount fit fine, it just didnt like launching with the WOT/2 Step.
I meant to say that to the person that broke his StreetUnit mount wondering if it was that old design. I guess I will place an order at Street Unit and play the waiting game...Well, the link above is to the OEM mount, not the "Stiff Diff". Make sure you buy this one:

It appears that it is a slightly different design than their original version. This one "looks" even better than the original. It has thicker bushing loops and bushings.
Will post photos when i get home, if you look in my garage thers pics of the broke stock mount and axle before i pulled them. not sure what version of SU mount it was, but got it late last year.Please post photos of the SU mount failure. Yours is the first I've heard about. Was it a production version or protoype pre-production? I've launched my Speed6 with the 2-step and with AP/LC set to 4600 and 4800 rpms with NO problems. We (the community) need to know details of any failures, please.
SU should be shipping back orders now, mine was on BO for a couple of months and I just got it today.900 for a mount, Yep, I'm doing it myself....
I should have mostly everything, I have stands and a jack but I don't know how a standard jack will fair with lowering the rear end....
Think you may be confused on the tt mounts. here are twop. U are correct in stating the tt front motor mount gives you a new mount. But there is a forward rear diff mount the tt has a mount to replace.The turbinetech mount does not replace a mount..but adds one. Some people get both that front mount and a stronger rear mount (SU or CPE)
I have just the front.. not installed.. anyone want to donate me a rear sway bar to install the same time?
