Mark,
Thank you for your interest in the Detroit Truetrac helical gear limited slip differential. Because of our late delivery of the Titan from Nissan before the SEMA Show, we only had time to make a single prototype for this unit. We plan to be in production with this application by the 2nd Qtr. of 2005.
Customer Service.

Tractech,
According to the attached document your email address was listed as a contact for information on truetrac differentials. According to a SEMA show and this Document a few Nissan titans were outfitted with a Detroit truetrac differential. I own a 04’ Nissan Titan 2wd SE and I am looking to replace my stock open diff with your Detroit Truetrac differential for more traction in preparation for a supercharger install. What exact part numbers would I need and how long do you think the average conversion for something like this take? Any Info would be greatly appreciated.
Thanks,
Mark
