9-bolt 7.75" New Parts (3.70 gear set & Install Kit)

I recently had some troubles with my 9 bolt and I've decided not to keep it. The following are brand new parts. They were sitting under my work bench waiting to be installed in the original boxes. I have excellent feedback here and on eBay. I accept Paypal. All pictures are clickable to larger versions.



3.73 (3.70 stamped on ring) Yukon Gear Set - From Randy's Ring and Pinion- Item Number: YG GM7.75-373BW. Retails $229. These are brand new in the packaging. I've opened the box a few times to inspect them and take pictures. My original invoice shows these as 3.70 ratio, noisey, for a 3.07 and up case. Installation booklet is still in the box. $210 Shipped



Yukon Master Overhaul Kit - From Randy's Ring and Pinion- Item Number YK GM7.75BW. Retails for $230. These are brand new in the sealed packaging. My original invoice shows these do not have side shims and website says no ring bolts. Installation booklet is still in the box. $210 Shipped

Want both? $380 Shipped That's $460 of parts shipped to your door. - SOLD



Girdle with stud kit - From TA Performance- Item Number: TA_1802 & TA 1802-SK. Retails $180 [including stud kit]. These are brand new the box. Studs and fastners are still sealed. Decal and original gasket are still there. This girdle is heavy ~7 lbs and is a monster when compared to the stamped cover. It has drain and fill plugs, bearing preload supports, and adds 1/2 pint to the fluid capacity. ARP Studs are for the main caps to replace the OEM bolts. The other included fastners are for the cover bolts. I've misplaced the instructions but they can be found on the forum. $170 Shipped - SOLD

Yes, I could do a US Postal Money Order. I'd of course have to make a trip to the Post Office (1 town away) first to cash it before sending any parts.

Email with address has been sent. Sale is now pending on the girdle cover.

I still have the gears and install kit. Anyone interested? Really need to get this moved to clean out garage and afford replacement rear end.

I have received the payment for the girdle. I should be able get that cashed and shipped today. I'll send you the information after.

Any takers for the gears and install kit? You'd pay $325 just for USED 3.70s without any new bearings from 9bolt.com or around $470-$480 for the same stuff at Randy's Ring and Pinion.

Re: 9-bolt 7.75" New Parts (3.73 gear set, Install Kit, and Girdle w/ studs)

I needed a ratio change for the camshaft, so I wanted to inspect it prior to having a shop put in the new gears. On teardown I found the carrier case has already been machined prior and the posi cones are bottomed out, so I can't get much more life out of it. I also found 2 of the 4 spider gear shafts broken. So instead of using my new parts and additional funds (for a posi carrier) I'm planning on a 9" in the future.

Anyone want to make me an offer on the parts? I'm tired of them sitting next to my computer desk.

I believe I have secured a used 10 bolt replacement so I don't plan on fixing up my 9 bolt currently.
