I have an 88 with a 350 and stock 10bolt with 3:73 front and rear with 35s. I was going to regear it with 4:88 and 38s but from the information I have read here I’ve decided to upgrade to 14 bolt in the rear. I will be in the sand or light trails for most of my off-road adventures do I need to upgrade the front axle? Or is there a better way to upgrade? Please help!
