Lock Your Front Axle at the Flip of a Switch for Awesome Levels of Traction

The trusty front 8.8" 31-Spline IFS axle in your 2009 to 2020 F150 does a pretty good job of taking care of your truck off-road, but it can't pull your truck out or over anything you'll find out in the wilderness, and due to steering issues, limited-slip differentials aren't the greatest idea. That's where Eaton's 8.8" 31-Spline Ford Front IFS ELocker comes in. This drop-in, electronic locking differential allows you to lock the differential at the push of a button, giving you the ability to lock your front tires together along the axle and pull your truck out of just about anything you can get into. Eaton's Elocker is built around an electromagnetic locking mechanism that captures all of the torque available to the front axle and sends it to both front wheels, allowing you and your truck to rip out of basically any jamb where you may find yourselves. Like all of Eaton's differentials, their ELocker is built using high-quality materials that won't let you or your truck down out there on the trail or the darkest of wilderness.

Extremely Strong Case and Internal Gearing with Complete Wiring Harness and Switch

The Eaton Elocker comes with everything you need to get it installed into your F150's front differential, and even includes an integrated wiring harness to make installation that much easier. Eaton builds each of their Elocker differentials with net-forged internal gears and a responsive electromagnetic locking mechanism all built into an extremely strong body that allows the ELocker to handle just about any application or off-road driving that you have mind. The integrated wiring harness comes with a grommet , relay, and switch making the system ready to wire up right out of the box.

Professional Install Recommended.

Requires Drilling: the differential requires drilling into your truck's front differential to run its wiring leads. Eaton includes a grommet for sealing the hole.

Fitment: the Eaton eLocker will only fit 31-spline front 8.8 IFS applications, like those found in 2009-2020 F150s with 4WD.

Would this e-locker work with the 2011-2016 F150 4WD Yukon Complete 4.11 Gear Swap Package? Can the e-locker be wired into the wiring of my factory locking rear diff?

Asked by: Andrew - 1/1/2017

The Eaton eLocker will fit with our Yukon 4.11 Gear Package. As far as tying it into the wiring for the factory rear eLocker, it may be possible, but we can't guarantee it, and personally, I don't recommend it. For one, any engagement of the rear differential will also lock the front regardless of whether or not you're in 4WD, which would put needless wear on the eLocker. Secondly, the factory rear eLocker only stays locked up to 35 mph, regardless of whether you pulled out the knob, while the Eaton unit can stay locked as long as you want as long as the switch is activated.

How much shop time to install this locker? What is average labor cost? Thanks

Asked by: Michael - 8/28/2016

Install time and labor costs will depend on the shop, but 6-8 hours sounds about right as far as time is concerned. That being said, your best bet would be to shop around locally to compare prices and to work out deals.

Are new bearings required for install? How detailed are the instructions? I am thinking of doing this next summer on my 15' F150.

Asked by: Brad - 12/8/2016

New bearings aren't necessarily required for installation, assuming that your truck doesn't have a ton of miles on it and that you manage to remove the stock bearings without damaging them (which is easier said than done). The installation instructions are a bit generic, to be honest, since they're general for all 8.8" IFS applications. We generally recommend a professional install, since installation is a bit intensive and requires drilling into your differential housing.

Will this work with 5.13 gears? I would like to run 37's.

Asked by: MArtin jackson - 4/23/2017

The locker will feasibly work fine with any ring-and-pinion gear set (including 5.13s) as long as the axles keep the Ford 8.8" 31-spline pattern.

So this locker will stay locked until we turn it off?? Correct ? Meaning as long as we have switch to on. It will stay locked regardless of mph ?

Asked by: Shamoo - 10/31/2018

Correct, though you'll still want to be careful with your speed with the axles locked. It's not impossible to shear a CV

This will work on rear end too

Asked by: chris - 2/22/2019

This differential will work on the rear ends of 2009-2014 F150s with an 8.8" rear end. However, it will not work on 2009-2019 F150s with a 9.75" rear end or a 2015-2019 F150s with a Super 8.8" rear end. If you're not sure about what rear end your F150 has, please call us directly at 623-434-5277.

What are the pros and cons with this Elocker vs. the ARB air locker. I have been told air lockers are better but they require much more to work (ie.onboard air).

Asked by: Brian B - 6/21/2019

ARB's Air Lockers are physically stronger than Eaton's eLocker, but you are correct in that the ARB Air Lockers are more complex and require an on-board compressor, air lines, and manifold for install. The Eaton solely requires wiring to your battery and a standard rocker single-function switch of some sort. Both require drilling into your truck's differential housing. In the end, unless you either already have a suitable on-board compressor or you're really going to be beating the heck out of your truck, the Eaton is probably the better bang-for-your-buck.

Does the differential has any important reliability-durability effect on drivetrain, suspension or steering?

Asked by: Gustavo - 7/31/2018

The differential itself won't effect longevity or durability of your truck's drivetrain/driveline components. However, how you use the thing and your truck will definitely have an impact. If you're doing the type of off-roading that justifies this differential, if you accidentally leave it engaged on pavement, if you get one of your CV axles extremely stuck and gun it, and other situations as such will not be kind to your F150's driveline in general.

Wil this elocker work on my 2006 f150 front differential as it looks the same from your pics?

Asked by: Don - 9/24/2019

It will not. The 2004-2008 F150s and the 2009-2019 F150s both use an 8.8" IFS. However, the 2004-2008 F150s use 28-spline CV shafts, and this differential will not fit. Unfortunately, Eaton does not have an eLocker for the 28-spline 8.8" IFS trucks.

Can the front end of a 150 really take this? Thinking of adding this to it to a 2018 as a way of adding in getting unstuck. Front end leveled, 33s, and tire chains in the snow. I’d be half scared it would twist something off? Or is trying to turn with them locked the real danger?

Asked by: Wyoming - 1/20/2020

The factory front CVs of the F150s are actually pretty stout. Now, it's not impossible to break one, especially if your tire is really jammed up and you're throwing a lot of power at the problem. However, for most general applications (i.e. snow), you likely won't have a problem. If you are concerned, we do have a few upgraded axles available.

Do you know if the 2018+ Expeditions with the 3.73 gears use the same 8.8” 31 spline differential as the F150?

Asked by: Eric - 8/18/2020

As far as I'm aware, the 2014-2020 Expeditions do use a 31-spline 8.8" IFS. However, I have not seen a complete part number break down for all of the components, so we can't outright guarantee that this differential will perfectly fit.

I just got off the phone with Eton and they claim Part # 19660-010 is for the 8.8 rear axle only and that they do not offer a locker for the IFS 8.8. Did you have to modify or adapt anything to make this fit other than the wiring hole? Thanks!

Asked by: Kevin - 11/2/2020

The locker will fit the front 8.8" IFS on the 2009-2019 F150s. The 2009-2019 front 8.8" uses 31-spline axles and C-clips like the rear. Since this is a locker and not an LSD with directional gears/clutches, there's no reason why this differential won't work on the front, though you do have to drill and use a grommet to run the wiring. We have not done an install ourselves as of yet (we are hoping to in the near future), but several customers have without issues.

I have a 2013 F 150 FX4 with the 3.5 ecoboost. Do all 2013 f150s with the 8.8 front differential have 31 splines? I also have 3:73 gears, if that helps. Thanks.

Asked by: Coop - 10/27/2021

Yep. All 2011-2014 F150s used the same front 8.8" 31-spline front axles.
