Blew my clutch last month, and in the process, shredded my gear teeth in the rear diff. Just had the clutch replaced but now would love a drop in replacement (3.07 or 3.55 gears) of a complete rear differential. May be far cheaper than having the shop do a rebuild. Any idea where I can find one WITH some form of warranty?

Your best bets would be to call:

1. Unitrax - not quite the same as they used to be back in the Viper's golden days, but still worth calling
2. One of the high performance Viper shops (Nth Moto, Calvo) - I'm guessing they end up upgrading rear diffs for their high HP builds, so they may have OEM take-offs available
3. Viper-specific scrap yards (e.g., X2 builders) - maybe stay away from ones that have rear collision damage :)

I'm not sure how likely you are to find something reasonably priced and with a warranty, but I wish you luck.

I know a guy here in central florida that claims he has a dozen Viper differential assemblies. I'll PM you my phone number so you can text me and I'll get you his info.

You might try this site/call the guy who owns it; he might have a connection or be able to sell you one with warranty.

I have a spare diff in my tool shed. Was clunking with too much play in the spiders, replaced the carrier assembly with a replacement and put new axle oil seals, now it sits underneath my work bench. I had found another on EBay and had this one fixed. It is a stock hydrolock 3.07

Based on my experience and the assumption, you have a gen3. Purchase a new WaveTrac unit and absolutely go with 3.55 gears. I noticed the LSD difference my first on ramp pull. The new gears make the car much easier amd enjoyable to operate. Have a good one.

I have a spare as well. Would love to sell. Stock unit. 3.73 gears. Spider gears are worn but I believe the rest is in good shape. What's it worth? Don't need it.

On topic/Off Topic...

I have a core that I was going to rebuild this fall and put on the shelf. Likely either a 307 or 355 Wavetrac G3/4 if anyone wanted to work an exchange. Just FYI.
