They do but they're outsourced (i.e., made by Motive- I asked that question specifically of the guy I talked to and he said yes).

I'm confused. Are they OEM or Ford Racing? They can't be both. The non-Motive gear FRPP gears are actually made by US Gear.

This is the description that is given on the website:

Description
OEM 8.8 4.10 rear end ring and pinion only. Manufactured by the Ford motor company. Fits all 8.8" rear axles, including IRS.

I don't know of any OEM 4.10 gears made by Ford so I assume that these are FRPP. For me, it won't make any difference if they're not FRPP but instead are OEM since I'm having the ring and pinion cryo treated anyway.

Ford does make some 4.10 OEM ring & pinions. They're designed to be quieter and aren't as tough as the Ford Racing gears.

My Ranger has a factory 4.10 rear. I just got my FRPP 4.10's back today from getting Mikronited. Now I just need to find someone with a lift I can use to install them.

OK, I just spent close to an hour taking pictures/talking on the phone with an FRRP tech. about the 4.10 gears I received from Late Model Restorations (LMR) in Texas. Here's the definitive word from FRRP on their USA-made 4.10 gear and pinion set:

(1) there is only ONE Ford 4.10 ring gear and pinion set made, NOT two (i.e., there is NOT an "OEM" set and a separate "Ford Racing Performance Parts" set with one being "non-forged" and the other "forged") ;

(2) the ONLY 4.10 ring gear and pinion set that Ford has EVER made in the USA (i.e., FRPP # M-4209-G410-A) has ALWAYS been made by Ford at its Sterling Axle Plant in Sterling Heights, MI, NOT by U.S Gear (historical note: Ford originally owned the plant, then Visteon took it over when it was "spun off" from Ford; now Ford has the plant back under its own name again);

(3) ANY and ALL 4.10 ring gear and pinion sets purchased at a Ford dealership and labeled M-4209-G410-A are domestically produced and are available through BOTH FRPP AND the dealerships- i.e., there is NO difference whatsoever between the two;

(4) any genuine USA-made 4.10 ring gear and pinion set made by Ford does NOT have the pinion depth marked on it- if it does, it's NOT made by Ford;

(5) not all genuine Ford ring gear and pinion sets have the Ford logo on them for reasons best known to Ford (probably a money-saver since the raised logo stamping costs money);

(6) ANY 4.10 ring gear and pinion set labeled M-4209-G410M ( not "A") is made for Ford by Motive Gear in Motive's Italian plant.

BTW, the ring gear and pinion set I received from LMR is the GENUINE USA-made FRPP 4.10 set that I ordered (at a GREAT price I might add).
