This is all good to hear. FRPP i assume?
I know that its all in the install with gear whine and such, but i hear that FRPP are easier to set up since you dont have to measure backspacing or something like you would with motives or richmond. You just have to measure backlash of course.
Are there any downsides to buying used gears? I dont see how there can be if the LOOK to be in good shape... You just have to make sure there are wear marks in the middle of each gear tread right?

The FRPP are easier to install do to the MHD design or something. I forget what that stands for but maybe somebody else knows...
EDIT: This is what i got from another forum.. Idk how true it is...
"Most shops that do gears often will charge you less for the Ford brand because they do not have to measure the backspacing depth since Ford's MHD design. All Ford gears use the same backspacing hence the name Master housing demision or MHD. So they can be done quicker with less tools. I have had two sets of gears put in my 02 and both the Richmond and Ford slipped right in with minimal shim adjusting. 3.90 is a nice ratio tall but not too tall."

Are you 100% on that? I have read on several accounts that the FRPP are easier to install for a reason similar to the one i stated a couple posts up...

I'm not sure where your source has gotten his info, but no matter which brand of gear I went with, I would approach the install exactly the same and with the same amount of tools.

i have heard about this and i ended up using the same shim when i did my install. i measured the pinion head thickness with a micrometer of both pinions and they happened to be the same, you just want to double check just be sure because if they arent they wont wear properly....i have 6 gear installs on mustangs already and not one of them had any noise related to gears of install, one had a bad pinion bearing which was easily replaced and the noise disappeared...installing gears isnt a hard job its just alot of stuff that has to be precise. all my installs i set the backlash on the tighter side, with the 4.10s i did i made it .006 because even at .008 it made a clanking/clunk sound when starting in 1st and resetting it tighter made it go away with no whine or anything, the wear on all the installs were perfect as well...if you have any questions on an install PM me or fizzicsboy on here because we both do the installs together flawlessly

i was thinking same thing recently but if you aren't doing install yourself some shops won't install used gears. If you find a shop that does and they make noise after install you could potentially run into an issue with installer: noise is from used gears.
I would buy new it is not much more and don't have to run into scenario I mentioned above.

Well to say you don't have to measure the pinion depth IMO is not smart. I would always measure it just to make sure.
Cisurfer, interesting that you found the .006" backlash better than the recommended range of .008-.012" on that gear set. Have you always set them to ~.006" or more towards .008"? When you installed that set at .006" were the teeth lining up right at the initial .008"?

Just out of curiousity, how much do u and fizzicsboy charge to install?
And which gear oil/friction modifier do u recommend/use?

i would just get new gears if you do get the used ones and they break or make noise or something like that then you lose the 70 bucks you spent AND then have to pay for the new ones to be installed again and that can be pricey.
