After having run an R160 4.11 on my stock L24 for some time, and looking ahead to when I do the swap to an L28 I already know I want to be running a slightly smaller gear - thus the 3.9... I've had a R180 4.375 r&p I've had on the shelf for some time but I don't think I am going to want to use it so:

I've decided I want to trade my R180 4.375 ring and pinion for a R180 3.9 r&p.

Is this something that would interest anyone?

Currently the ring is loose on my work bench while the pinion is still in its diff casing - so maybe for simplicity's sake and if you are in the SoCal neighborhood you could trade me for a loose 3.9 ring and a matching pinion still in its diff case? definitely not mandatory but that is a possibility.

I am interested in the 4.375 ring and pinion as long as they are in good shape. I dont have a 3.90 for tread right now but I am willing to pay cash. and for shipping. (assuming fair price) ( I live in las Vegas). I am in a big hurry because I have a race on the 22nd. of this month. Please email me as soon as possible so I can send you a cashiers check if you are interested. If you dont mind give me your phone # so I can talk to you. call me at (702) 873-0502 collect is fine

I really would want a 3.9 in trade or else I am SOL for my R180 LSD I am building... but what kind of $$ did you have in mind if you were to buy it outright?

$125.00 seems fair, I do have a 3.9 if a locker is ok for you (both tires turn at same time (proffesionaly done)

How much do you want for the 4.38, I do have a 4.11 R180. Better to have cash to finish your 3.9 than having the 4.38 sitting in your garage. Have you thought about just getting a standard r180 (dirt cheap) and your 3.9 to put one together
