Product Description

Mustang 4.10 Gear Kit
These Ford Performance Mustang 4.10 gears are a great way to improve acceleration to make your Mustang faster! This kit fits 1986-2009 Mustang with an 8.8" rear end. The kit features a set of Ford Performance 4.10 gears, an FPRP M-4210-B2 bearing kit, a bottle of Ford Performance friction modifier, and 2 bottles of Royal Purple 75W90 gear oil. The bearing kit includes a GT500 pinion bearing, new carrier bearings, pinion seal, ring gear bolts, pinion nut, crush sleeve, shims, and marking compound. With this kit, you can get your gear installation completed quickly and easily.

Ford Performance Friction Modifier
Ford Performance friction modifier is a specially formulated additive to provide smooth operation of clutch-type, limited-slip differentials. One bottle of friction modifier is required when changing the gear oil in rear ends equipped with Ford traction-lock units.

Royal Purple Max-Gear Oil
Royal Purple Max-Gear gear oil is an ultra-tough automotive gear oil. It’s designed to maximize power and provide unsurpassed protection to heavily loaded gears. It makes gears run smoother, quieter, cooler and longer without overhauls. Max-Gear outperforms other gear oils because it combines the highest quality synthetic oils with Royal Purple’s proprietary Synslide additive technology.

Installation Note
Although the Royal Purple gear oil has friction modifier mixed in, it is still recommended that you use the bottle of Ford Performance friction modifier to supply your 8.8 rear end with the proper amount of modifier.

Kit includes:
(1) Ford Performance Performance Parts 4.10:1 gearset
(1) FPRP M-4210-B2 bearing kit (includes GT500 pinion bearing, carrier bearings, pinion seal, ring gear bolts, pinion nut, crush sleeve, shims, and marking compound)

    5 Stars   Got Gears? Try this kit!
    By on 2/24/2014
    If you are installing a new gear set this is the best kit I have seen. Absolutely complete, including an extra crush sleeve (which I didn't have to use because of the great instructions), high quality gear lube and additive. In my humble opinion going from 3:55 to 3:73 does not make a substantial enough difference. I like to really feel my changes - wow did the step to 4:10 change the seat of the pants feel. I shopped long and hard to find the best kit at the best price - look no further!

    Great quality products, as to be expected with Ford Racing and Royal Purple... However, LMR did NOT include a new rear diff gasket for the install, as it shows in the photos.. which is a bummer!

    4 Stars   Major improvement.
    By on 9/13/2014
    This set of gears really woke my pony up. I only gave this kit 4 stars because it did not include new axle seals and bearings. Kind of stupid since replacing the gears means removing the axles.

    Also I ordered 4.10 gears but received 3.73 gears. The Ford Racing box even said 4.10 but I side were 3.73. Once I called Late Model Restoration and sen them photo proof of the box labeling and the gears stamped 373, they sent me out the correct set of gears that same day. And they paid the shipping of the return. Long story short, good gears and company. Mistakes happen. I will continue to use Ford Racing products and I will continue to buy from LMR.

    Image uploaded by James A. This kit have everything you need. The gears are quite and smooth. I highly recommend these quality parts for your 8.8 Mustang rearend. The 4.10 ratio works perfect with my Trackheat H/C/I kit and World Class T-5 with a 2.95 1st gear.
    For the money, you can't get a better kit and, as always, the customer service here at Latemodel Resto is second to none!!

    5 Stars   Amazing product. Fast delivery!
    By on 12/30/2014
    I bought this kit for my 94 gt. Everything fit perfectly and the car accelerates like a rocket! The only thing I would have added is rear axle bearings and seals. Not a huge problem cause they're only 20 buck at any local parts store. If you're gonn do this upgrade I recomme picking those up since you have to take the axles out anyway.

    5 Stars   The best upgrade yet.
    By on 1/17/2016
    I put these 4.10's on my 01 cobra. The car pulls so much harder now. I'd recommend buying axle seals and bearings along with this kit (my seals happened to be leaking). The acceleration difference between the factory 3.27's and these 4.10's is mind blowing. Love love love!

    By on 2/12/2015
    just got the 4:10 gear in my 2001 mustang gt. This is the way to go with an automatic. A lot more torque off the line. Ford racing products are very high rated in my book.

    5 Stars   4.10 gears
    By on 4/16/2015
    You can read review after review and not see much bad about this. Yeah it drops your top end speed, but for daily driver when are you gonna be clocking 140+MPH. (Not on the street anyways, I hope.) This upgrade will kick you in the pants from a dig. You need to allow 500 or so breakin miles but after that... instant smiles. Kit comes with everything you need. You want to pick up the Trac Lok carbon disc rebuild kit, and some Axle bearings and seals so you can to the whole kabootle at once. This stuff all together will make you feel 1000lbs less and give you peace of mind knowing something isnt going to fail due to the added torque.

    5 Stars   Best Gear for the S197
    By on 9/18/2014
    Kit comes complete with everything you need. I was happy to see the install kit - bearings, seals, friction additive was all genuine Ford Motorsport and not knock off brands like in other kits sold by other distributors . Ships very quickly even on the east coast.

    The 4.10s wakes up your S197, and with the standard, and driving highway isn't bad at all. Well with the upgrade.

    5 Stars   Great Product
    By on 3/14/2016
    Fit great. Appears to be well manufactured. I have used several Ford racing gears and never have had a complaint. A rear gear should be one of the 1st mods to a stock Fox. It might be a little low for some people. 2300-2500 rpm at a steady 60-65 cruise. Best bang for the buck in my opinion.
