Wanting to throw in some 3.73 gears and an Eaton Posi-unit but having trouble. I have a 2007 NNBS Silverado 1500 2x4. Problem I'm running into is trying to find the right gears and posi-unit. Some gear sets come with the ABS Reluctor ring or able to install and some do not. I cannot find out if my truck has the reluctor ring. Chevrolet cannot confirm nor deny, I'm basically at a standstill trying to figure out where and what gears and posi I can buy that will match up and not have to return. Thank you!

 

Check to see if there is a connector on your rear differential, most of the time they are on top of the diff. If not then no abs reluctor. Mines also a 07 and has no ring. Maybe the newer trucks with stabilicrap and traction control have that on them? Need more? Pop the rear cover off and check lol.

 

Thank you for your help. Only thing I see on the diff is like a vacuum line coming from the top and a clamp on the axle which are two lines going from each drum which is either speed or ABS sensors.

 

Non reluctor wheel it is. Buy away with whatever gears/locker u want.

 

Awesome! Thanks for the help man. Gonna order from Ron's Machinery. Getting some 3.73 with a posi!

 

No problem. Thats where i got mine from lol.

 

+2 for Ron's.
