For those that were looking for and bought a rear 2010+ rear differential for your 2008, how long did it take you to find one? How often were you looking on www.car-parts.com? Did it seem to take awhile? Are there any other websites that you went on to find a rear diff?

The junkyard near San Diego has a rear diff but for a 2008...so I have to keep searching.

I found one the first search I made online. The wrecker was located 35 min away from where I live so it was very convenient. They had two at the time I bought mine and I was thinking of grabbing both just to have a spare. I payed $730 tax in if I remember correctly and i knew they would be very sought after hence the reason to buy both but I decided to let another member have the chance at snagging it. I've looked periodically for another one but I've had no luck.

I watched the first two people get them, then had to wait 4 months checking almost every day. Then finally got one for $850 out of a 2011 in northern CA with 11k totaled, hadnt been in the yard a day he said when I called. Blitz got one after me somewhere and i think he was the last one to get one... its been months 5 months sense then.

Well it's still an "ELSD"...

Our diffs ratio is 2.937:1 from 2008 to 2013
With Torsen added 10'+

Only swap I would consider would be the OEM IS-F LSD Torsen unit..

Great write up and general feedback is similar to my experience. I say just save up and get the OSG unit. Its going to be twice as much or perhaps 3x after install but it behaves locked all the time which eliminates the need for a loss of traction event to engage. I have periodically looked for people and these cars are just not getting wrecked. If you have an 08 09 its such a pronounced upgrade. Make your mods count.

im currently looking at the toms lsd as it is not bad price wise. I can't find the oem torsen so I might go aftermarket. there is not a lot of info on the toms so i was wondering if someone can shed more light on the toms lsd before I make a purchase...

never mind just found some info but for cusco...
