Used to run a spool rear (60) and ARB front (44), Ran the ARB for 9 years and the only thing I had to replace was the O-rings in the diff. Now I am Detroits front and rear and love em. Steering radius is half of what iot used to be and I can't even tell the front one is there but both tires pull???? Can't tell the rear is there either unless I try to drive on the pavement like I was 18 again?:redneck:
