Hey guys i am looking for some advice with the proper gear selection and locker set up..

first i am using the set of axles that you guys helped me identify. Front hp Bj D60. has stock 4.10's and the matching sterling 10.25 with 4.10's. i want to use 5.38. i will be running 42-44's on this truck pirmaraly in the mud and fire roads. and some local mud bogs.. i am thinking about a detroit in the rear and a spool up front with manual locking hubs. my question is what carrier do i need for the front. dont i need rev thick gears on the 4.10 carrier? and the ring mounts right to the spool conrrect? thanks alot.. on the other had i might just weld the front.

They make 5:86's for sterlings now? :confused:

Well after some more shopping and research, Looks like i will be doing 5.38's front and rear due to the sterling. i will be running a detroit in the rear because this truck does get driven on the street. (it has to be driven to the mudd bogs to be in the stock class)..
My plan now is to get all this stuff from Randy's ring and pinion, any one know of a better place??

Ummm yeah the ring gear bolts to the spool. In this case if you run 5:38's tell Randy's (talk with Chad) the gear you want and they will send a matching spool. You can run either the thick cut gears or standard.

after a lil more searching. i think i will just use the 5.38 rev thick gears in the d60 and just weld the spiders.. then i will put the detroit in the rear with matching 5.38's..

Well you obviously haven't read the D60 bible...

Carrier break on the D60 at 4.10, so you will either need a new carrier to run anything bigger, or run the thick gears.

10.25 has no carrier break, but it wouldn't matter if it did since you're getting a locker for it.

Yeah Performance Offroad Center has better prices, by like $10. Both have free shipping.

Read the D60 bible, and all of the other tech articles, you need it.

i read the d60 bible.. but the hp d60 is still a lil hazy in there... according to that the hp d60 has no carrier split.. will check out that other dealer... thanks..

the d60 bible is wrong you will need thick cut gears or a 4.56 and up carrier. we can help you get anything you need. we are cometitive w/ both randys and PORC. check our site for prices or give us a call.

yeah right now i have decided on the cheaper way out in the front. with think cut 5.38's and welding up the spiders... insted of a 4.56 spool and thin 5.38's.. unless some one gets me a killer deal on one!!:D and the deroit is the only thin that is killing me for the rear.

weld that 60 up. I did mine that way over 3 years ago.

I was surfing on porc and found a full install kit for 589.99.. it includes Both gear sets, and two timken master install kits.. in 5.38 ratio. Here is the link. http://www.performanceoffroadcenter.com/oscommerce/product_info.php?products_id=3986

If pre-98 fords were offered w/ carriers that were for 4.56 & up gears, then yes the 60 bible is wrong. but if not, then I think it is correct... read the **
that said, I don't know if fords before 98 were offered w/ 4.56 and up carriers, but IIRC snowfighters and others had lower gear ratios than 4.10


Carrier split, reverse cut: All use same carrier **

** Note: The carrier is the same for all Ford RC 60's UP TO 98, and is the same as the GM/Dodge 4.10 carrier - namely part # 706040X.
BUT - the Ford RC60 was never offered stock with a ratio lower than 4.10 in those years. When aftermarket vendors started making gears lower than 4.10 for RC 60s - they made the ring gear thick, so it could just go on the stock carrier. So if you bought aftermarket 5.38 gears for RC60 - they would likely be thick. Now - if you buy an aftermarket carrier (i.e. locker, spool, limited slip) for your RC60 - I imagine, depending on where you buy it from, they ask "year/make/model" and based on that would likely sell you the 4.10 down Detroit - that way - if you already had aftermarket lower gears, they would just go on the locker. The problem you might run into, is this:. You buy aftermarket gears first - lower than 4.10 and they're thick. Then you buy a locker by ratio, not make and model, and naturally you'd think "I have 5.13 gears - I must need the 4.56 and up locker" but you get hooped because the gears are thick, and won't go on that carrier. Also note, The 2000+ RC60 Fords are offered with stock gears as low as 5.38 - but these are not thick to go on the same old 4.10 down carrier - they are thin and go on the same GM/Dodge 4.56 up carrier. The carrier break is 4.30 and down go on the 4.10 and down carrier. I don't know if Spicer is the only manufacturer offering thin RC60 gears - but the bottom line is - when dealing with an RC60, you do have to match your carrier and gear set.


all that said, that PORC deal seems like a good deal to me. I'd do it if I were looking for Yukons. Instead, I'm trying to sell mine.

what PORC is selling isn't Yukon I don't think... at least it doesn't state if they are

Yeah as i looked through that ad i didnt see what brand the gears are.. but they talked them up with no name brand. i will have to call them tomorrow.

They are PORC's brand he has them cut for him as his brand, just like yukon has theres cut as there brand and or randy's brand, they are most likely cut in the same factory. Yukon does not manufacture/cut any of there own gears. US gear, Precison and others cut them for them along with some foreign companies abroad that have the machinery.

By and large the best aftermarket gear on the market is Precsion gear and US Gear. US Gears selection is just limited. thats why these two are the most expensive.

If I was going to buy Yukons I would buy PORC gears, he at least warranties his for life, as oppossed to Yukon's I believe 1 year warranty. They are overpriced for what they are. The biggest problem is you don't know if they are going to be good or not, b/c you don't know where they are coming from some of them are great some of them are not. It all depends on who manufacturers them.

I might as well pimp my own stuff so here you go (my shameless plug) w/ a pirate 10% discount and you also get free shipping, I believe this to be the best deal out there, based on proven quality, maybe not the cheapest, but so be it. Your looking at $725 total shipped on your door.

Back to tech, you need thick cut gears or you need a 4.56 carrier as I said previously, all the d60 bible is saying is if you have a 4.56 carrier already then you need thin cut gears. the problem with that is for HP60 thin cut gears in the 5.38 flavor are more expensive than a thick cut gear, so it is cheaper better to run 4.56 down carrier witht thick cut gears even if you had the carrier already.

And finally PORC is a great company and has good products that is a good deal.

I am digging through your site right now.. the link you posted brings me to and empty cart?? so the price you listed is for both front and rear ring and pinion sets in 5.38 flavor, both master install kits and shipped to my door? with five year waranty on ring and pinions.. what does the waranty cover??

Warranty covers parts.

Duh!! lets hear a lil more about the warranty, how do you warranty a set of gears? say i shock load them and snap some teeth off a ring or pinion??

Ill send you a brand new set, If you break them, I don't care how you break them. Provided the pattern is not total shit.

I responded to your PM... your best bet is to call Cperry and go his route, you aren't going to beat that for new parts/warranty...


...just install them properly or have someone else if you can't

i can set up gears so that is no problem, and i have the tools. i will think about the percision gears. any one running them on a dd? just curious how much noise they tend to make? i will be running boggers or tsl's so i probably wont hear them over the tires..
