Just installed a 9" rear end from Scott at DLS
Here are some pics. I installed it today and I took it out for the initial break in. So far so good.

Not anymore! I ets'ed last week. where in kentucky are you at?
and i love the street twin... not too much pedal pressure and i have yet to have it even think about slipping on me.... only downside is there is a little clutch clatter..... If I could, I would hump my street twin if there wasn't a bell housing stopping me.

I just wanted to finish the write up I started on this DLS 9 inch. I have about 500 miles on the rear end and I followed the recommended break in procedure. I drove it like a granny for the first four heat cycles. Each heat cycle I drove it about 30 miles.
Quietness:
The gears are completely silent except for a slight whine between 40 and 60 on decel. It is much quieter than my old ten bolt which whined at all speeds accell or decell. The whine is hardly even noticeable unless your really listening for it. My wife still doesn't hear it!
Handling:
The car sits at the exact height it did before. The differential centered itself nicely so I didn't need an adjustable panhard. The rear end is heavier so the car feels more stable. The trutrac differential gives a very solid feel going around corners. My wife noticed the difference in handling immediately and was very pleased with it as was I.
Traction:
This is the biggest gain of all. This car hooks extremely well now. I think it is a combination of the extra weight in the rear and the trutrac posi. I used to smoke the tires in 3rd gear at 50 mph with my ten bolt, now I can barely manage a scratch in second. Huge difference. I have heard others complain of a loss in RWHP when installing a 9 inch but in my case I didn't notice any appreciable loss in HP.
Ease of Install:
This job was very time consuming (2 full days). However there was nothing overly difficult about it. I had to have the bearings pressed on. Primer and Paint the new rear end. Come up with a conversion U joint for my Lingenfelter aluminum driveshaft 1330/1350. Adjust the torque arm. BFH the inside of the driveshaft tunnel for clearance. Clearance the center section for the torque arm mount. I also had to buy a sway bar kit from spohn which was a very good investment. The new spohn mounts come with longer end links and poly bushings that correct the geometry on the sway bar. The sway bar hangs down pretty low and can be seen from the rear of car which I thought gave it a classic muscle car look from the rear.
Strength:
I've taken the car to 6200 rpm and 15psi and I'm not getting any extra noises or whines. It just feels very solid. Only time will tell I guess. My lt4 clutch is not good enough to do any serious clutch dumps so I haven't given it that kind of abuse. Next project is a rebuilt T56 and McLeod street twin.
Was it worth what I spent:
Heck ya. I would have spent twice that much money just for the ability to hook. The increase handling benefit and being able to hear my stereo at highway speeds is an additional bonus. I think anyone who is having trouble hooking should start with a good differential before even trying rear lca's, panhards, sway bars, air bags, etc.
Hope this helps.
