RPM/DSS Polyurethane Torque tube Couplers? Whats your opinion?
 

Who is using them and what is your opinion?

I'm talking about the ones RPM sells made by the Driveshaft Shop.

Figured this is the best place to ask, since many guys here have upgraded drivetrains. Have a nice later model tube getting ready to go in and was thinking of running them instead of OEM rubber.

Been running them for a few yrs already no problems.

putting them in my car

I have them with a carbon drive shaft seem to work just fine.

RPM all the way here have the Level VII trans from rpm both couplers and the driveshop 3in driveshift. Also running a C6 z06 cradle and Rick worked me up a c6 z06 rear for the car also. Robert

Yeah, car already has an RPM Lvl 4 T56 in it.

Any increased tube noise over the stock rubber couplers?

Thanks for the opinions.. keep em coming.

I have them in my car too... RPM/DSS is an unbeatabe combination...! :thumbs:

That is what I recommend if the stock couplers are on it's way out. I wouldn't use anything else! :thumbs:

At what point would you upgrade to these over stock on a car that is not tracked?

If you have much over 450 rwhp and you run the hel* out of it I would look at doing it for sure. Better safe than sorry alot of guy dont do nothing until it breaks. I look at it as INS from breaking that plus even more parts....:thumbs::thumbs: Robert

I have been running this combo for awhile now . You don't
even know you have them on. If you run big hp this is good
insurance even though they are pricey.

:iagree:

:rock: That's the way to do it! Bulletproof!

My only real concern was with noise/vibration.

Looks like I will be ordering a set of these couplers this week :)

Thanks

I dunno, I'm not convinced. I run the OEM couplers and haven't had any problem with them. If I did, that's when I would determine if an upgrade was necessary. I just wish it was easier to inspect them.

You are running big power. The stock couplers could be falling
apart right now and you wouldn't know it. When they let go
you are going to have more damage then a couple of couplers.
Think about it but not too long. Good luck.

I believe his car was converted to an auto, which should have slightly less shock to the couplers vs. a 6 speed (ie. dumping the clutch). That is a lot of power though, this car will be nowhere near that.

That's what I used to think. So I went thru my torque tube last year, and the couplers were good as new. I just haven't seen any evidence to support that couplers are prone to failure, or that poly couplers are any better.

I think the stock couplers are ok to about 800 if you're not going to beat the hell out of the car and esp if you have an auto. I'm running stock but I have an auto and I don't shock the car that much. If I run my car harder I will switch to the poly couplers.

Yes I have an auto now, and when it was a stick making 700, it saw plenty of 5K clutch dumps on sticky tires and never had a coupler issue. I remember a thread from BLOWNBLUEZ06 when his DSS poly couplers were twisting up with around 1000rwhp. Possibly something to do with the shape that's perfectly round, as opposed to the hexagon shape of the stockers? I never heard how that worked out for him.
