Monroe Sensa-Trac 58643 Shocks

Guy's & Professionals that Be ...

I was looking at purchasing these shocks and have read some on here about the added coil spring around the shock would cause undue stress on the shock mounts. I have a 2008 F150 Supercrew 4X4 5.4L that needs some new shocks.

Here's a picture:



Just looking for advise!

Thanks!

My advice...walk away.

Buy a good shock that does what it's supposed to.

If you're doing serious hauling/towing that exceeds the capabilities of your current springs, then address that issue separately. If that is an issue, these things are a band-aid.

Thanks, I only haul things occasionally for things such as mulch, pulling a boat etc.

Try Air Bags

What you need are Air Bags, not more stress on your shock mounts.

Try this or do a search for F150 Air Bags.

From what you explained, you don't even need air bags.

Thanks guys!

I really just wanted to see if I could prevent that rear-end squat when hauling mulch. I have a 1" leveling kit on the truck and love the stance and looks, "except for that twice a year" trip to get mulch and saw someone else here mention putting these on and gaining an extra 1/2" to 1" in height in hopes to stop the mulch sag.

I also read that the shock mounts were not up to handling the tension put on them by the coil. Guess I should just go with a regular shock.

Thanks once again.

Do you really want to mod your truck based on what you do 99.46% of the year because of what it looks like the other .54% of the year??

If so, and if it bothers you that bad, get air bags. When not in use, they don't exist. Meaning they have zero influence over the ride or stance.

Thumbs up

I have Air Lift air bags on my Merc (not on the F-150 ... yet). They do work to support loads and maintain ride height. They do not jack one up past their ability to expand. You can make them rock hard. They will be noticed even when near "empty" ... not bad, but noticeable. Better than extra spring leaves as long as lines stay away from exhaust pipes and sharp objects.

Ive used those on both of my older fords (93 & 97) w/o ever having any issues... Other than they can be a pain to put on w/o a compression tool... Like you I only occasionally hauled my 4wheeler in the bed or a trailer w/ a bit of load on it. The $$ of airbags was not justifiable.

Just occurred to me, my Dad used some shocks like those in OP, "Monroe Load Levelers" I think they were called. That was in the '60s. Back in about 1981 I helped a budy remove a cab from a 64 Ford SB PU and he let me have the frame and bed (frame front was bent, he just wanted cab itself) and I made a trailer of it .... it also had Monroe Load Levelers on it .... they are still on it .... I sold trailer to another buddy who uses it still.

Those were an older style non gas and non pressurized regular heavy duty twin tube shocks with spring, now they use pressurized gas shocks .... they work.

Well, I went ahead and installed these shocks. I figured as little as I hauled stuff and I was really after appearance and just alittle more rake and the cost why not. I didn't have a load of mulch so I drove the four wheeler in the bed. On fairly level ground the truck visually appeared a little higher in the rear than level, meaning the rear looked somewhat higher than the front. I dont know how much mulch weighs but I figured the four wheeler would be a good test. Oh! the ride seems better with the new shocks. Here are some pics.

Yep...definitely looks high in the rear. Glad you like it since you're the one that's gotta drive it.
