Shelby 8.8 needs special pinion bearing

[wbt]

To what recommendations/suggestions do you refer? As stated in my original post, I swapped gears and rebuilt the rear end prior to posting this.

Truth be told, I will follow the advice of someone like Van or Justin (who, by the way, have nothing to gain as neither sells this part) before unknown members on an internet forum. Make sense?

I'd like to make the Texas Mile. Never been to it and it sounds like fun. You going as a spectator or a competitor?

Pit crew for a friend. We usually park by Van. Jon Lund will have his twin turbo 2011 out there with Ken B. so should be a blast.

Shoot over a PM with your name and/or team. If I make it I'll come by to say howdy.

the reason the shim is included in the rear with the updated bearing was for noise reasons. it was a combined piece to reduce gear noise. im not saying the shim was the only piece but the thinner bearing assembly will transmit less high frequency noise than a bearing of equal or greater surface area. it was almost like a retrofit to reduce gear whine without a major overhaul. in the end they kept it as there was a definitive loss in noise over the standard bearing.

i would also listen to the guys who work on them all day everyday, im not detracting that from anyone. if they want to sell it over a standard i say go for it. maybe they have seen a difference...i dont know. i do know that when i went through my FMC training we did plenty of driveline testing with no ill effects from bearing size or load. our stupid 3 link design was the hamper of the entire s197 chassis and plagued test cars.

anyways, ill see if i can contact an old buddy who is still in the game to grab you a part number to update this. could it be that timken does not make the bearing?

Thanks Kevin. I think everyone would benefit if we could identify the individual part number.

And by the way, the bearing/race assembly had "Timken" stamped on it and a part number. Nobody seems to be able to find it. So if you come up with something, let us know. I just looked in the FRPP catalog last night, and it does not list this item separately, only with the B1 kit.

i completely forgot about this thread, i will check today and get back on it.

I just wanted to add, FRPP now offers a bearing kit for all 86-up 8.8 rearends that uses the high torque GT500 bearing. That should solidify the fact that the high torque bearing is interchangeable with the standard bearing.

I can confirm the newer deluxe ford rear end rebuild kits do contain the "High Torque" bearing and it will work in a standard 8.8 rear the only problem is that due to the lack of the proper bearing race spacer that some or all of the 2007+ SVT mustangs come with, its a real pain to get the gears set up. Without the spacer, you have to shim the inner bearing substantially more to get a perfect contact pattern, avoid gear whine AND set proper preload. I had to overload the bearings to keep from loose pinion decel howl and will have to replace the bearings with the proper set before too long or my rear end will no doubt fail. Old post but after all the headaches I've been through, thought I'd share. lol.

This is the part number listed in Tasca Ford for the my 2013 GT500 rear end. 6L2Z-4625-AB

That is the correct number.

That is the correct number.

Yeah, that was $23.68

You're right about the part number I gave as being the same as the old style bearing. I pulled one and checked it compared with the prior number. It's not the new style bearing. However, you can without a doubt remove the shim and use the old style bearing. The housing itself is exactly the same. There is no reason it wouldn't work. We have done a few of them without a problem.

I have installed the GT pinion bearing and race in my Shelby GT500 and have had no issues what so ever.
