You can get 3.73 and 3.42 gears for it fairly reasonable. Rockauto has a USA Standard 3.73 gearset for $150 bucks. The 3.42 is a little harder to come by, but you can expect to pay around $300 for it. If your carrier bearings are good you can get by pinion just a pinion install kit rather than the full rebuild kit, saving some $$. As far as axle bearings go, the real advantage is the full floating hubs. http://eastcoastgearsupply.com/i-12009997-gm-10-5-14-bolt-ring-pinion-3-42-oe.html | | |
