Tremor Rear Shock Options

[High_Country]

It might be helpful to have a thread dedicated to upgrading/replacing the rear shocks. We've got some great threads for leveling kits, a rear spring thread started, etc. It seems the consensus is the rear shocks leave much to be desired. This would be such a (relatively) low cost and low effort issue to address by replacing them with better components.

I've seen these referenced from Eibach (thanks @TxT):

What else is out there for a rear shock option?

(It seems it would be an easy exercise to remove the factory shock and measure compressed and extended lengths for reference.)


This is a list copied from page 5 to give an idea of known measurements for rear shocks.

Good idea, watching.

While not a shock, I am planning on adding the Roadmaster Active Suspension (standard duty). I believe it will help with axle wrap and improve the ride.

Ford F-150 (4WD) 2021 -2024 | SD Kit

Kit includes an easy to install RAS® Standard Duty Spring for each rear leaf spring. This kit is designed to strengthen the rear leaf springs for light towing or hauling while providing same-as or better-than-stock unloaded ride and performance. This 3-in-1 solution works like a helper spring...

I have been impressed with a set of Bilstein 5100's I've had on our 2015 4Runner Trail since nearly new. It dramatically improved the ride and handling (was honestly shocked - no pun intended - at the difference just shocks made). They have to have some options for our trucks - if not explicitly stated, at least that would work. On their website they list 5100's for the previous gen F150's for:
0-1" rear lifted height
2" rear lifted height
4" rear lifted height

And their 5160 is listed for 0-2" rear lifted height:

Did rear shocks change from the '20 and earlier models to the '21+ for F150s? I had planned on doing the Fox 2.0 as I have them on my '17 and they are an improvement over stock, but Fox's website doesnt list an option for '21+ F150s.

Anything that accepts up to a 1.5" lift from gen13.
Fox 2.5 are 2" and Fox 2.0 may also be.
I'm unsure about Icons since they don't actually tell you measurements
Eibach's are 1.5" and was the best $100 I spent, so far.

Sweet, I thought you were getting these. You'll have to give us a full review!

Will do. Earliest install is this weekend. If I can get them in, I'll do a loop with my 8k trailer

Here’s another Bilstein 5100 option - extended and compressed lengths nearly identical to the Fox referenced above.

Bilstein 0-1" Rear Lift Shocks for 2015-2023 Ford F-150 4WD

Bilstein 0-1" Rear Lift Shocks for 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023 Ford F-150 4WD Part: 2x33-253190 Need the full kit? [product sku="47

www.bilsteinlifts.com

Looks like we’re looking for a shock that is about 28.5-29.0” extended and 17.5-18.0 compressed (based on the published info from the fox and bilstein).

With a minimum of 9" of travel allowed, there are lots of options out there. Pick a price and a brand and you can find it.

Stupid newbie question but this is my first vehicle with leaf springs. Are shocks the limiter for (downward) suspension travel in the rear?

Not counting u joint geometry I guess.

 

[Yeti]

Generally it's the springs. In some cases, there will be a limiting strap but most times the weight of thebrear end isn't enough to overcome the arc and length of the spring.

Unless a graboid is wrapped around your axle, then standard physics do not apply

Is this the method you are trying to use to offset the leveling while retaining towing capabilities without going nose up? Or did I misunderand your intent?

It is. I'm only looking for up to a 2" lift in total and my thought is that adding a way to help the rear leaf springs not sag so much will end up giving me what I'm looking for. My tow payload is ~ 1,000 pounds with most of that on the hitch and my overland payload is about the same in the bed. I'm more function over aesthetics so some rake won't push my buttons, too much.

 

[Brad99superd]

Sorry for a silly question guys, which Bilstein shock would be used for a completely stock Tremor then? I see they have 0-1", 2", 4". Just confused if we consider the 2" lift block or not or since it's stock I would order the 0-1" shock.

Thanks again fella's!

By the way this is for future, I'm a long ways off from getting my truck I'm afraid lol

 

[Captain]

@Yeti Stage3 specifically mentions the Eibach sport shock (E60-35-035-02-01) as not being long enough/incompatible with the Tremor. What gives?

not sure, honestly. They also say we have a 3" rear block. Maybe I'll plan my trip to AZ, this year and let them take a look. Heck, I may even swing by when they receive my Icons.

It’s about an inch shorter than our stock one. I installed anyway and fine so far lol

Thanks for the responses fella's, I'll keep an eye out for this thread while I wait ever so impatiently!
