Off Roading ARB D80 Air Locker and Dodge/Dana Hybrid 80 Rear Differential...

Will this air locker work with the factory Dodge rear axle?

I think you want it for the D70HD (Heavy Duty), 35 spline, not the D80.

Axle

You have a Dana 80 in the truck listed in your signature. You will need a locker that will accept your 35 spline axles. All stick shift trucks with Dana axles have Dana 80 rear end and automatics have Dana 70s. Sam

It looks like the D80 35-spline is what you want based on that application chart, but obviously check with a good supplier.



What we have on our trucks is a D80 center with D70 tubes and axles (35-spline).



Outside of the Dodge world the closest thing to a drop-in rear diff for our truck is a D70HD. This is a D80 carrier drilled for a D70 ring gear and is 35-spline. If you re-drill this carrier for a D80 ring gear then it drops right into our truck. Several suppliers sell the D70HD already re-drilled for the D80 ring gear.

Can you specify "supplier(s)?"



I believe the D80 supercedes the D70HD?
