The differences between the RPG fox's and the icons is more apparent at normal driving speeds off road.
At high speed, they both kick ass. The fox's droop out quicker for a bit more control, but the icons take a massive front hit (endo !) a bit better.
At lower speeds, the digressive damping...
Jack up the truck by the a arm on both sides, grab a wheel and wiggle it vertically and horizontally. You'll probably notice the noise before that though.
Or when you see your alignment guy throwing wrenches at the side of your truck :rotflmao:
Same here with my rpg's.
I went over everything three times to find out wtf was loose.
Just the minimal rebound damping in the ride zone.
You'll be happy to have it when you're in an off camber turn cresting a hill at 80mph offroad.
The thumping is annoying in some situations, but still...
The stock springs are a better choice due to their overload spring and higher rate.
The others are more for performance.
Your only option is the sdhq air bag setup, or the RPG long bump stops.
There's two ways to build a truck for snow.
One is a solid axle with lots of lift and tall skinny tires. Typically a heavier vehicle. The solid axle weight transfers in a way that keeps the tires on something firm.
The idea is to cut through with minimal drag.
The second is usually ifs...
I think about it like this:
I've owned a lot of trucks, and ford, Chevy, dodge, etc. they're all pretty much the same.
A 1/2 ton ford doesn't really do anything different or better than a 1/2 ton chevy.
A 1 ton dodge diesel doesn't really do anything more or different than a 1 ton diesel...
What you are missing here is that the intercooler that's shedding the heat is sitting in front of the radiator.
Less cooling for the engine.
The more heat from compression ratio in a n/a builds is a moot point, as you have to look at how much hp a blower motor is actually making.
The blower...
I'd say get the +2 hd springs then.
You could get away with the +3 standards if you're not running too much tongue weight on the trailer.
By loading the truck up with that stuff though you will be attempting to reach a compromise with the springs.
You can have it ride as soft as possible loaded...
+2 is the most common.
I've got +3, and if there's nothing in my bed, the rear was always higher with both the icons and the fox's.
The +3 is more for someone who always has 300 pounds of gear in the bed.
No, the compression adjusters actually don't change the compression that much.
See big j's shock dyno thread for more info.
The icons have more potential for doing this, but are currently valved too stiffly to use their compression adjusters this way. Their softest setting is suitable for high...
I like the fox's compliance on smaller stuff, washboard, expansion joints, that kind of stuff.
Anything it can drop a wheel into like potholes gives the fast droop and "thump".
Kind of sucks, but it's a trade off for a cushier ride on everything else and suction cup like behaviour at high...
I might do some testing of a set of fox 3.0 rears that have been valved specifically for cold weather later this winter. But no plans in the near future.
With the icons on all four corners and the nationals out back, I found the rear to ride much better than the front.
The icons would actually...
I'm running goodyear duratracs at 38 psi.
If you went to a softer spring rate the compression and rebound would definitely need to be adjusted.
The high rebound damping is a byproduct of the stiffer spring rate, and part of why you were seeing your truck rocking back and forth with slower...
The shin guards, the adjustment knobs, and the silent valve seats.
Mainly the shin guards though, that's a huge feature to me since I'm offroad all day, every day.
And I don't feel that the rear end is lacking at all, they are working very well indeed.
It'd look the same more or less.
Because you can't tell what's going on outside the vehicle.
I started shooting video, but it really doesn't convey what you're actually feeling.
For slow speed across washboard stuff it would have been dramatic, but there is so much more going on with the...
