Can I use the BMR transmission crossmember that relocates the torque arm with the TH400? I found conflicting posts in the swap thread. What length tail do I need on the TH400?

I am hoping all I have to do is buy Spohn's adapter.

Thanks,
Kevin

you have a spohn tq arm? If so and it is a chassis mount, just get the crossmember with out the tq arm mount. The BMR is setup to fit the short tail th400 but i slotted the mounting plate so it would fit my 9" tailshaft.

I am running the BMR transmission mounted torque arm, but using the BMR crossmemeber to get it off the transmission.

If you have a stock style tq arm, htn the BMR th400 crossmember with TQ arm relocation will work for you, regardless which manufacturer the tq arm was made from. If you already have a spohn chssis mount arm, a regular TH400 crossmember from bmr is all you need. It will work with a short or long tailshaft TH400, you'll just have to grind the mount a little where the trans bushing attaches to the crossmember for a long tailshaft tranny... that is what BMR told me before I bought the crossmember, a chromoly stock style tq arm and their d.s loop. Hope this helps!

I am swapping from an M6 to the 400. I have read that there are two different lenth tails you can get with the 400 and you can use the M6 style crossmember with one of them. I was hoping someone could verify which tail would work with my existing M6 crossmember. I am running the BMR M6 crossmember that relocates the BMR torque arm off of the transmission.

the short tailshaft will work but it is not an exact fit...you need to mod it a little

So if you end up with the long tailshaft it will not fit, or you have to do a lot more to get it to work?

I have seen that BMR and Yank both make crossmembers for the TH400 with integrated torque arm mounts. Spohn makes a mount for the TH 400 that is supposed to get it to the right height and use the stock crossmember.

None of these sponsors have anything to say about what length tailshaft you need to have to use these mounts.

I know Lee at BMR said he made his crossmember to fit a short tailshaft. i have the long and had to notch his crossmember a bit...no biggie. No idea about yanks
