I have an M1123 truck with MAK removed. It has a soft top and soft doors on it - truck is used as an off road toy. Since I've gotten it, I've removed the MAK springs and replaced them with softer ones all around, but the shock absorbers are still beating the piss out of us off road. I've been...

These engines run notoriously low oil pressure. I remember my Dad being concerned with the low oil pressure in our 6.2L diesel Chevrolet that we bought new. The head diesel tech at Chevy said 10psi at hot idle is normal when running straight 30 weight oil (it was 1985). We had that vehicle...

Mogman, thanks for the arrows...I love an easy fix!

I'm having an issue with my turn signal. I noticed the pecker that engages the wheel ring was not centered. I removed the cover and saw this. I cannot figure out how this rotating lever centers itself...something has to be missing.

Not entirely true. The MAK spring rate is too high to compress with the unloaded vehicle at any sane speed...and when it does finally compress the rebound shoves the chassis upward with such force that it launches things / people out of the vehicle that aren't strapped in at speeds that a leaf...

MAK is Marine Armor Kit. The MAK springs are used with the MAK armor. From what I read the MAK armor weighs 3500# - so the MAK springs are designed to work on a vehicle that weighs #3500 more than my vehicle currently does - thus the stiff ride. Yes, the M1123 is an A2. I did not cut...

I just went thru all of this. My 1123 was MAK'd and still had the 3k springs on it. I just replaced the rear springs with variable rate (did the cast uppers, the front lower bolt is not even close to being fun to remove). I did the front springs with the 954lb and disconnected the sway bar...

I also did a flex test where I put RF and LR in the air. I measured the top of the tire to the bottom of wheel well to see how much flex I'm getting. All numbers in inches - positive Delta means spring is compressed. The gravel road test shows that the MAK shocks are contributing to the...

I unbolted the front shocks and drove down my gravel road. Still couldnt do much more than 13 mph, but it was better than the 8 mph I was doing before.

Searching google does work better than searching SS directly…who would have thought??

I found this in another thread, this must be the cast mount with variable rate spring, and I must have the stamped with the MAK spring? Now I need to find a softer spring that works with my spring mounts and maintain ride height

I'm not sure what the different spring mounts look like, but the front and rears appear to be the same. Would I have to change them out to use a lighter spring? These are the rears.

Thanks, I've been doing a lot of searching and reading on the topic and keep coming up with conflicting information. The 4x4parts link agrees with the other dimensions I've seen - I have not really started looking for springs yet, but I see that they have the stock variable rate springs as...

Does anyone have the compressed and uncompressed length for the shocks? Thanks! Mine is an M1123 that was previously uparmored.

That is what I figured. The large mesh under the grille can't be helping anything either...It's like a snow fence, for your grille!

I’m having this same exact issue with my M1123. Throttle was sticking at halfway and not returning to idle. I removed the screw #9 to keep the throttle from sticking while I get the parts and fix that plunger. I’m only driving it locally without that cam screw engaged - but it definitely...

Is it normal for the engine fan on an M1123 to engage while driving on flat ground? Doing 45mph on a relatively flat (for Tennessee) road and the engine fan engages for a few minutes then shuts off for about 2x longer than it was engaged. I’m asking as my Chevy diesel pickup truck only engages...

Took delivery on Wednesday of my M1123, SF-97 arrived on Thursday. I've had the HMMWV for 2 days now and it already has plates and insurance! I have no idea how this all happened so fast!

Thanks everyone! I was not aware of mac motors or kascar. I've added both sites to my list of sources. Good call on checking the filter for algae and slime.
