Ford doesn't make their on gears so someone in the aftermarket world is making them and putting in a ford box.

Now why do you want go and invite all those to jump in and **** & moan and start their BS with how their brother's uncle's sister's friend had 1 gear set (rear only) installed in their 1981 2WD F150 for a lot less.

Seriously though - $2,400 front & rear, turn key with complete warranty ($600 parts / $1,800 labor)

All haters please keep your comments on the price keep to yourself

Thats right on the money, ive seen the tickets myself from a reputable shop, not some backyard driveway

Then you install them in your F150!!

I have been through the gear set game with my GT 500 and the FRPP gear sets are the only gear sets that are OEM quite.

Yeah the average price from a dealer that's worth a f*** and knows what they're doing will be $2,200 - $2,400. The dealer I chose has done lots of gear set changes in 2015/16 F150s and knows what they're getting into. This isn't their first rodeo in the modification world. They are a Roush, FRPP, etc. dealer and have been doing a lot of non-factory installations on F series trucks and Mustangs.

I am driving 150 miles one way just to take it to this dealer.

Totally not true. Have 4:10s in a 2000 mustang GT and a lowered 05 Chevy 2wd 4dr truck. None are FRPP gears and they are totally quite, no hum and no whine whatsoever. Gear whine is most always caused by the installer not the manufacturer but I do understand your concern totally.

I'm ecstatic you've had good experiences with aftermarket gear sets...

I am also glad your not running FRPP gears in your 05 Chevy 2wd 4dr truck.

I've seen lots of Motive, Yukon, etc. gear sets get removed because they were noisy. I'm not going down that road.

Same here, although usually in the lower ratios (4.56 - 4.88 etc). The factory gears are machined using a two-cut method also known as hobbing. This produces more of a sweeping contact pattern and typically quiet. Aftermarket gears are milled using a five-cut process. The aftermarket is just starting to come around. Five cut milling is actually very durable, and was how hypoid gear sets were made for generations. If properly spec'ed and lapped they are excellent. The problem is almost all aftermarket gear sets are made in China for export, and the production standards are not tremendously high. I re-geared my '05 to 4.56 and never did get a completely quiet set. I tried Yukon, which was very noisy, and two sets of Sierras. Sierra #2 is acceptable, but I'm not thrilled because I still have a whine between 47 and 52 mph. Sticking with factory gears definitely has it's merits.

Thank you !!

If someone else wants to install a brand x gear set that's fine. My experience has been less that favorable with most non OEM or FRPP gear sets.

by the way here's a great website w/calculator if you are considering a gear set change and would like to determine what ratio to use
