Ford Shock mounts on front of JK (raised/ stem to eyelet)

Swapped a set of Ford shock mounts / towers into the 13 JK. Between raising the upper mount and switching from a stem to an eyelet it raised the upper mount about 3"+-. With only a 2" bump stop, there is room for about a 19 1/2" collapsed length shock.

with a little trimming of the middle on the bottom, they fit really well. Along with moving the mount up and swapping to an eyelet, they also move the upper mount out slightly to get the shock away from the frame.

Awesome. What kind of shocks are you running? And about 12 or 13" of travel?

Right now, Pro Comp ES9000 with a collapsed length of 19.42", an extended length of 34", and a 14.58" stroke.

Whats the cost? I mean you can buy shock towers from several fabrication companies for $50.

Some build info here:

You can get them for around $15-$20 each depending on where you get them from. They are a factory Ford part, so they can also be sourced from junk yards or from junk trucks. They are cheap, simple and work well with the available space.

Part number is E5TZ-18183-A

$30-$40 for a pair is alot cheaper than anything I've found from fabrication companies. Most of the similar mounts from them get into more of a coilover mount that costs considerably more and are not made to fit beside the coil bucket or tube style shock hoops that again takes up considerably more space and still cost more.

Nice travel right there! You using all of it? How much chrome at full bump?

Just got them put in yesterday so can't really say for sure.

I hope to use as much of the travel as possible in the Metalcloak 3.5" coils (have 2.5" now and the 3.5" waiting to be installed). They have a solid height of 8" and a free length of 22" with 14" of travel. After I get the suspension done and decide on which Bias tire and size I'm going to run I will see what I have and adjust from there.

At full bump, it's going to be close. I didn't quite get metal on metal last night but at about 1" away, there was just a little over 1" (1"-1.25")of chrome showing. It's close but will be fine. At ride height with the 2.5" coils I have about 3 3/4" of compression and with the 3.5" coils I should be right about 5" of compression.

I may have to steal your idea with those shock towers. That’s going to be some nice droop without having to run struts or coil overs. Good job

Always great to see old become new again. We've used those mounts on CJ's for years as there is plenty of material there to adjust height significantly and the perfectly flat back makes for a clean weld or bolt-in application. There are a couple of local Ford houses that actually keep those in stock due to the popularity on other platforms.

Nice work here!

Steal it and improve on it. Thats why I shared it, I wanted others to see how using Ford shock towers / mounts on a Jeep JK / JKU would works out. Relocating shock mounts and using the Ford shock mounts was/is pretty common on other Wrangler models but not very common with the JK. It's something that can benefit a wide range of builds and lift heights. Making room for a longer stroke shock without limiting/reducing suspension travel by extending bump stops is a good thing. It allows you to gain travel without trading sprung travel for unsprung travel which is often done.

It's really a pretty easy swap if you can weld. Without a 1"-1.25" body lift, you can gain around 2" and with a 1.25" BL you can get around 3". The mount is moved outward about 1" or so (will have to get a good measurement to say more accurately) and even that can be altered by trimming the bottom at a different angle.

Exactly. I've used these on a TJ on the front and also to outboard the rear of the TJ. It was common on CJ, YJ, TJ and even Suzuk Samurai ( actually ordered these from Low Range) builds and forums but very little if any mention of them and I have not found any use of them in the JK /JKU builds/forums.

You are right though, It's an old idea that could become new again. I am by far not the creator of this idea, I just used them on a platform that you don't normally see them used on.

You running a 1310 or 1350 driveshaft? My 1310 binds a bit at full droop with 11” travel shocks. I’m sure a 1350 may have more misalignment

1310 front shaft and the rear is stock that is up for replacement when I redo the rear suspension. There's a few things I'll have to keep an eye on and fine tune. It's not a throw'em on and forget about it fit.

What's the extended length of you 11" shocks? Is the lower/axle mount stock or has it been rotated and moved up for frame clearance?

After making some adjustments to the brake lines, YesI am able to use all of the travel in the shock. It takes some work to get the last 1" (after the jounce bumper makes contact) compressed but it does it.

Still haven't had time to get the rear upper mounts in and a longer rear shock installed. Hoping to get them done this spring/summer.

Yes slightly under 11”. The lower mount is in its stock position but that may change soon now that I just got this shiny new welder. it’s a little over 27” extended length.

@-SLADE-

First, this is awesome.
I would so love to see more of this ( I think we will) type
of ingenuity for the jk. Really cool.

second , from all the questions , it sure might be cool
to snag a few more images of the setup , maybe from the
lower mount looking frwd & from about 6' ?

Only if you can .

Thanks again for sharing the wealth , man .

I'm going to pull the Boggers off and put the 37" STT Pros back on this weekend (still a little early to run Boggers on a DD), Ill be able to get a few more pictures then.

The difference between upper mounting points.
Shock specs are measured from Center to Center of the eyelets on a shock with eyelets on both ends.
The measurments on an Eye/stem shock is taken from the center of the eyelet to the end of the chrome shaft (not between the 2 flat bushings).

The extended length comparison of the old shocks vs new shocks was pretty significant. The old stem shocks were around 28" and the new shocks are around 34".

By reducing the amount of bump stop needed and raising the upper shock mount, you are able to better keep your suspension travel sprung and at full droop the axle is not pulled under the Jeep like it would be with the same length shock in the stock mount. The available sprung travel is detirmined by the coil springs solid height and free length. 2dr JKs are at a disadvantage compared to 4dr JKUs because the coils have a shorter spring length until you get into really tall lifts. When I first started looking at mild lift coils for my JK, alot of the 2"-2.5" lift coils had a free length comparable to some of the stock JKU coils.
With the exception of Metalcloak's 6 pack shocks, a shock with a long stroke has to have a fairly long collapsed length. To fit the long collapsed length shock without raising the upper mount or lowering the lower mount, you have to extend your bump stops. Bump stops limit/reduce suspension travel to prevent shocks from bottoming out and to increase tire clearance. If you rely solely on bump stops to give you the clearance needed for a shock with a long stroke, you end up trading sprung travel for un-sprung travel (after the coil spring reaches its free length and unseats from the coil bucket). Not a good trade in my opinion.



The 1.25" Body Lift made a big difference in increasing sprung suspension travel. It reduced the amount of bump stop needed for tire clearance by 1.25" (front and rear). The Body Lift also allowed the upper shock mount to be moved up an additional 1.25" which allows for a longer collapsed length shock that has a longer stroke. Even if you only credit the body lift for allowing for 2" of additional sprung travel, That's almost a 25% increase over stock and almost 15% of a 14" stroke shock. 2" does not account for the additional stroke in the longer collapsed length shock which also contributes to increased travel.

I wanted to limit the amount of bump stop needed for tire clearance to 2"-2.5" at most. The front has around a 2.25"-2.5" bump stop, the rear has 2" bump stops and I'm running a 38.5x13.50x17 Super Swamper Bogger (had to do a little trimming). The 37" Cooper STT Pros fit about as perfect as it gets though.

These show how the Ford mount was cut/notched to fit up against the coil bucket. It's a pretty easy cut to make and can be cut to adjust the angle and depth of the mount.

Clearance looks good sitting level but at full stuff/droop/lock it looks like the tire is going to be rubbing hard in there. You are on the right track about adjusting shock mounts and clearancing for up travel rather than just adding long travel shocks and bump stops. better balance and stability. Another benefit is better drive line angles since your overall droop is less than what a factory jeep has.
