First Fox 2.5 Lift?

[RotorHead695]

I think this is the first Fox 2.5 lift I have seen. He was able to fit 295/70R18 tires. The one thing I noticed is that when looking up the part number for the front shocks they are only showing a travel of 4.5". Seems like maybe he intentionally took a suspension performance hit just to get the height. Am I missing something?

Yeah,

I seen that post. Nice stance but I'm not willing to loose that travel

Someone mentions the Fox 2.5 has 4.5” of travel and stock has 9” — let’s gather up the data and compare.

Stock

vs.

Front - Fox 2.5 Factory Race Series Coilover Reservoir Shock Set 883-02-133
Rear - Fox 2.5 Factory Series Reservoir Shock Set 883-24-002

Strangely, the coilovers he has specified appear to be incorrect. That number seems to be for a Chevy Colorado/GMC Canyon, and the rears are for an F150 and show a 0-1.5” lift.

Anyway — below is what Fox has for a 2020 F150.

https://www.ridefox.com/subhome.php?m=truck&make=Ford&model=F-150+&year=2020&position=ALL

Lets assume we are after a 4”-6” lift with the 883-06-114 coilover setup. Travel is listed at 5.59”.

Okay here is what I found on the stock Tremor suspension in MotorTrend:

2021 Ford F-150 Raptor Versus 2021 Ford F-150 Tremor

Take a look at our specs comparison between the 2021 Ford F-150 Raptor and the 2021 Ford F-150 Tremor!

www.motortrend.com

Suspension travel is increased by 1.5 inches in the rear and by 1 inch in the front over a standard F-150 (which puts it at roughly 9 inches of wheel travel).

So we appear to be talking about two different things — wheel travel and shock travel:

Wheel Travel is the vertical (up/down) distance the wheel can travel. · Shock Travel is the change in shock length through out the wheel travel.

Agreed, I won't sacrifice that either....that's a 50% loss! Why even bother with getting a Tremor if you are going to do that?

That someone is me. I could be totally wrong in assuming the strut needs the same amount of travel as the entire wheel and control arm.

Yeah...Fox doesn't have any compatible ones that peak my interest yet, and those are 2020 fitment. The ones he chose would have come from the "universal fit" section. I am looking for a set that will go up to 3" and made for the 2021.

 

[RotorHead695]

So the Fox shocks for the Raptor have a 7.9" of travel. I'm guessing they didn't sacrifice the 14" of normal travel, so the shock must not need to extend the entire distance and just pivot in the LCA?

Lol - ok.

So what is the actual shock travel for the OEM Tremor or standard F150 (Suspension travel is increased by 1.5 inches in the rear and by 1 inch in the front over a standard F-150) suspension so we can compare?

 

[P0H0]

You know I am thinking, travel can’t be the end all of suspension superiority. What about dampening and how much force it takes to compress — these factors may require less or more travel.

I need a beer.

So the Fox website doesn’t list anything for the 2021 F150. I guess the folks putting on Fox 2.0 and 2.5 are guessing and going for it.

Agreed...I'd rather be patient and wait for a solution approved by the manufacturers. Even Ford Performance said not to use the 2020 2.0s on a 2021.

Wheel travel is an extension of shock travel. It depends on the connection point of the top as offset and the bottom as arc from the pivot at the lca to the center hub + wheel offset
Dampening, etc are based on leverage of truck weight applied to those same points

 

[Yeti]

Here's something that will bake your brain.
The more perpendicular a shock is to a wheels line of travel (at the center of the wheel], the more potential wheel travel there is.

But, that also means the less effective the shock is

Icon mentions the f150 in their products up to a 1.5" lift for tremor. My concern about these adjustable is the increased spring compression and stiffer ride

An adjustable setup should help with this — I am not sure how many setting there typically are, but if you want to soften the ride, you can do it.

 

[Yeti]

unless suspension has changed in the last couple years, if you compress a spring to get ride height, you're still compressing the spring.

 

[RussTTU]

Just so everyone knows. Shock travel is 4.5 up and 4.5 down. 9 inches of total travel so thats the same as stock.

I put 2-1/2” leveling kit on a F 150 Tremor and 295 70 R 18 work well.
