What ring gear size do I have?

[jmccracken1214]

I have a 98 suburban k2500, in changing my transfer case seals and the pinion seals need it to. Do I have the 10.5” ring gear? It’s got the 14 bolt with 4.10 gears

Easiest way is to look at the shape of the rear cover.

Thank you!! I have the semi float.

Glad I didnt order the 10.5" seals!

Quickest way to ID semi float vs. full float is the full float has the big hub sticking out with the 8 bolts holding the axles in. Can't miss it. Example pic is from a dually rear but the SRW full floater has the same hub.

Perhaps a moderator will move this out of "Garage" and into "Axles + Brakes".

2500s more frequently have the semi floating axle(9.5" ring gear). They would have to have been ordered that way, to have a full floating axle, 10.5" ring gear. The one tons got this axle automatically. But I have seen a few K2500 Burbs that had the full floating axle (probably special ordered for towing as these also have big blocks).

My K2500 has a 10.5", but it's also a 7.4L.

The big-block 2500s got the 10.5" rather than the 9.5" of the small-blocks. No doubt the bigger axle could be ordered with the small-blocks if y' checked the right option box, and paid extra.
