Nitro's new AAM 11.8", 4.30 ratio gears are what every diesel owner has been
waiting for. The larger 11.8“ diameter increases the strength of your rear axle
overall, while still fitting inside the older ll.5" housing. Of course 2014 8. newer
models have the larger 11.8" housing already, but now you can install the much
desired 4.30:1 gears that have been sought after for so long. We have taken all
the bearing guess work out of these builds and detailed what Master Kit you will
need based on year & model. For a complete, no fuss, one part number over-
haul, check out our Gear Packages which include both front & rear gears and
front & rear Master Kits!
