Ranger rear axle swap
I have a 1992 Ford ranger 4x2 3.0L standard transmission. Its a 4 speed with overdrive. Truck has good get up and go off the line but on highway when i hit over 110km/h revs sit around 3000. Any way i could maybe swap a mustang diff or any other ideas on the problem? Just got the need for speed. Seems almost pointless to do up the motor and have it limited by the drive line. Ideas would be very welcome.
