Hey all, im looking into getting some 3.73's for my truck this week and i wanted to know a ballpark figure for a gear install. All i have in the rear end now are 3.08's. Should i take it to a good mechanic in my area or bring it to the Ford dealership? Will they charge me around the same price or will Ford be more expensive?
Thanks in advance.

 

I made the same switch (except I have the 4.6L V8). Definitely worth the money for me. I bought and installed my gears at a speed shop for $450 (about $70 of that was for the fluid available only at the Ford dealer!). I spent another $100 on bearings for the axle but the guy who did the swap said that the shims were in too tight from the factory and caused excessive wear. The dealers seem too be very expensive on any type of work - I suspect that the dealer gets a large portion of that and the person actually doing the work is NOT getting rich!!

Good luck!

Jim

 

The labor is usually around $300. Total prices can range from $550-$650 per axle. You may find a reputable mechanic at either place; a recommendation from a friend can be handy.

 

If price is your concern then I definately would not take it to the ford dealership. I am not sure if a ford dealership does the work they will warranty it or keep the truck under the original warranty. You shouldn't pay more than $400-$500 dollars per axle.

 

I was quoted around $550 for everything at a local shop. There was some discussion on this before, and I think the average was around $600.

 

They quoted me $1048 for 9.75 swap to 4.10 gears on one axle!

 

$1749. for the front and rear to 4.56. I almost swallowed the phone when my mouth hit the floor

 

Could the wide price range be because some of the lower gears (4.11 & 4.56) require a change of the carrier also? Right there you're looking at ~$500 additional. Something to keep in mind before ya start bashing vendors for price gouging. Also, www.drivetrainwarehouse.com, the place with "Guaranteed Low Pricing, Free Lifetime Warranty" IS part of 4wheel parts wholesalers. Just some info for ya.

 

I am getting ready to install 4.10 gears and a Powertrax no-slip. The shop that is doing the job said nothing about needing a new carrier. I was quoted 650 and that included new carrier bearings, new axel bearings, new axel seals and the install of the Powertrax unit (I bought the unit myself). This was on the 8.8 LS rear. The real problem is that not many places have the specialty equipment to do the gear installs.

 

I am sorry but they let me keep the quote and there is no carrier listed on it and they would not take my word on the long pinion set for 2000+ trucks with the 1/2" longer pinion gear. BTW for the 9.75 the only aftermarket ratios I have been able to find are 4.10 and 4.56...

I was wrong above I said $1048 when in actuality it is $1084

Here it is for one axle :
Ring and Pinion 4.10 - $359.95
Solid Spacer Kit (shims that is not needed with the right Ring and Pinion set) - $34.95
Install kit for a 9.75 - $189.95
Gear Oil - $12.50
Oil Disposal fee - $2.50
Lubes/Cleaners/Towels/Hardware (?) - $10.00
Labor - $425.00
Misc (?) - $25.00
Tax - $50.11
Total - $1,084.96


Lastly if you need to see for yourself I can scan the actual quote for the whole world to see...

 

Barnett Performance in Atlanta has gears for $180 an axle, in stock. There is a $90 kit for it that includes shims, bearings, seals, etc. That's all you need besides install, which I have been quoted from $150 to $325 locally.

I decided to go with an Auburn Pro LSD in the rear @ $350 from the same place. Prices varied greatly. The same LSD I paid $350 for was about the same at 4 wheel parts (not in stock, though), and $550 (!) from another local off road shop.

 

they wanted $1480 for auburn posi and 4.10's installed on my truck(9.75). one axle by the way. getting it done for $1100 at autostylz in lake forest. best price i haave found. parts are here and waiting for an appointment.

 

**** thats is high. The r&p should be about $150, install kit~$100 and the lalour is about $150 too high. WTF is the "Misc" charge of $25? and being charged for towels etc. is a bunch of ****.
I last message was jsut thrown out there thinking that some diffs required a carrier change around 3.5:1 ratio and was something for others to keep in mind.

 

rockit, where can you find a ring and pinion for a 9.75" diff in a 4.10 ratio at that price? i dont think so, but you tell me where and ill do it.

 

H*ll, I may be talking out my butt, but I see no reason why it would be much more than for a 9", any Dana gears or Corp. gearset. I've never dealt with a 9.75 so is there some specs. on the r&p that boosts the price up?
