1986 R22.. auto trans.
I changed my rear end gear from 4.10 to 4.56.. Helped tremendously w/ torque.. Could use a little more..
Tires 185/14/60 ...Thinking of going to 175, just on the rear wheels, for a little more torque.
175s = 1/4" smaller side wall.. lowers the rear of the rig 1/2".. but I have air bag suspension.. so rear sits high now..
Anyone tried this..??
