I didn't do my homework or read between the lines correctly and bought a 9 " third member with 3.70 gears and what I thought was a traction lok. However, after receiving the unit and talking with the seller, I realized that it is a torque lok rear with the powertrax components. The seller appears to be a good guy and has offered a full refund but I wanted to get some feedback on this type of system before I make my decision.

Is it strong enough for 350 to 400 horsepower and is it noisy when you go around corners? Thanks for any input.

Does the unit have teeth or clutches? If it has teeth then yes it will make noises but as far as I know Detroit Lockers are the only ones with teeth. I don't see any reason why it won't handle 350-400 HP. Powertrax has been around for a long time and makes good products. Now if you are running all out drag slicks then you should be running a spool, but otherwise keep and run what you've got.

If for any reason your not happy with it, I'd be willing to take it off your hands. I am looking for that exact set-up but have found shipping cost prohibitive on sucha heavy item, therefore I am keeping an eye out for one nearby within driving distance.

The seller said it was the spring loaded type. I'm thinking that is the clutch type, right?

CHRISCADE, I think I am going to try it out and if I don't like it or change my mind I will let you know.

No, The Richmond Powertrax comes in two flavours.

The original is purely a toothed gear. It is the ratcheting of the tooth gear that makes the noise. It is a very strong unit. I have one in my 9 inch. It does make some ratcheting noise but I don't find it objectionable.

They also offer a newer PowerTrax locker that manages the ratcheting with the springs but is still a locker. I have not seen one but would expect it is just as strong and is advertised as being quiet.

fwiw, if it has clutches it is a limited slip, ie Traction-Loc. If it is toothed it is a locker. It is the teeth meshing that cause the 'lock'
