Rear End Options - Pros/Cons?

**CALL911** · 09-14-2008, 02:17 PM

I've got well over 600 RWHP, and take mine to the track with slicks (at least half a dozen times a year). My Moser 12 bolt has lasted years (5 and counting) without a single problem.

Back when I got mine, they were a bit more money. I payed $2500 for mine. You can now get some killer deals. The Moser 12 is great, but didn't fit in as perfectly as I had hoped. Nothing major, but had to get some relocation brackets for the rear sway bar.

If I were to do it again, I'd probably go with the Strange 12 bolt like Fastbird did.

General rule of thumb from a guy who HAS installed them all.

The 12 bolt is great for automatic cars.(I have one in mine) Will die in Stick cars that drag race fast.

Nine Inch. Great for Stick cars but no 3 channel ABS(most LTx cars are three channel) unless you get Moser M9

Dana 60 is still new in our configuration. time will tell so far so good.

BTW the Strange still has the little issue you are complaining about as the Moser

NOW IF you can find a KTRE 12 bolt they are the best but they are kind of like unicorns LOL!

BTW 9 in takes the most floor clearancing of them all

I went with the Midwest Chassis 9". After talking with Eric on the phone I learned the following: comes with relocation brackets, custom TA (tunnel or trans mounted your choice), drain and fill plugs, has an option for 3 channel abs, priced cheaper than an S60 and the same weight as a 12 bolt (he claims same as 10 bolt with alum. center). I didn't want to loose the abs so conventional 9" was out. I didn't want to have to shorten my driveshaft and the added weight of the S60. I was afraid of the notiorus noise from the 12 bolt. After buying all the rear suspension accesories I spent about the same or less than if I'd pieced together parts for a 12 bolt or S60. LCA's, PHB, and TA are rod ended chromolly and the front mount of the TA and LCA brackets on the rear have 5 holes each for tons of adjustability. As an added bonus the tunnel mounted TA has a DS loop for no extra charge. It has Motive gears, Trutrac posi, Moser 31 spline axles, and a Strange SS third member (setup by him ready to bolt into the housing) Total cost was just under $3500.00 with all options and shipping. I added things like powder coating of all parts, a back brace, 3 channel abs, and a rear drag bar. The entire setup bolted right in with no modification issues at all. That's why I went with the Midwest Chassis 9".

go 9in or s60 james

You cant beat a 9inch for the price, and the S60 is "Just as strong". Now the 9inch does rob more power because of the offset of the pinion,but the 9inch is the only rear diff you have a pinion support.

Also I built my Moser w/ 31 spine for 1600....and some change

I went with the S60. I ordered it from Midwest chassis and performance. After figuring the price it was cheaper then there 9-inch. But there 9-inch comes with a torque arm. The thing is the S60 comes with new brake mounts at no extra cost from strange. There 9-inch you have to buy new ones or send them yours. I wanted to keep the break mounts on my stock rear in case I wanted to swap rears back if I sell the car.

So my S60 cost me with new drive shaft and shipped $2900 and some change. It bolted right in no problems all my suspension stuff I had on stock rear went right on.
Pic:

Midwest 9-inch with new break mounts would have cost $3500 shipped. But would have came with the new torque arm.

I'm happy with my S60. I have no gear whine hell it is quieter than the stock one that was in it. But I have a M6 and your an auto you probably don't need that much of a rear. I also drive mine as much as I can when its nice out and has about 5,000 miles on it now.
