Has anyone tried a locking rear diff. Looking to see what will fit my 3.55 ratio, 9.25" unit. This van was converted by PleasureWay into a camper. It weights around 8k to 9k lbs. Putting a reman'd 360 and trans in it also.
THanks for any suggestions.

 

Go with something like . Make sure the spline count matches your axles though.....

Are you sure that's a 9.25 in a one ton van??

 

Holy cow that is heavy! The GVWR for my 1st gen Cummins is 8510!
5300 on my B150.

 

It's a 'camper van' conversion by a commercial company, PleasureWay. So it has shower/toilet, cooktop, airconditioner, heater, generator, microwave and finish cabinetry throughout. That also includes three water tanks, fresh, gray, and crap.
As to the rear end, just reading the sticker under the engine hood for the ratio and gear size.
Also, I have read that the Detroit Locker is a bit noisy. Anyone have experience with the air operated lockers?

 

Air operated can be complicated. Need compressed air, and plumbing back to the rear diff. And the install isn't fun either. One of the (many) reasons I prefer an automatic locker... or limited slip. Detroit locker can indeed by loud, and until you get used to it, you might think your rear end was getting ready to blow up.

That's why I like the True Track. Its a gear driven fully automatic limited slip. No clutches to wear out, no harsh banging when it lock/unlocks, and no interesting behavior on corners like you can get with a locker. (especially the air lockers, that only unlock when you tell them to....)

 

The is a Trutrac clone that's on a good sale at Amazon right now ($365). The ARB will run in the $1100 to $1300 range usually just for the locker...plus another $220 for the ARB CKSA12 (only good for locker actuation). Don't get me wrong, they're worth EVERY penny on an off-road vehicle like a Jeep or Rover, just not really worth it on most street-use vehicles (my JK has ARBs front & rear). I would definitely stay away from the Detroit Lockers for street use. The manufacturer (Eaton) actually specifically talks about this on the https://www.eaton.com/us/en-us/products/differentials-traction-control/aftermarket-differentials/detroit-locker-faqs.html, midway down. Most people find them unbearable on the street.
