Default 4 Wheel Parts says this is normal...???

This is my second lifted truck so I have some familiarity. I have a 2017 with a 6" stage 2 Procomp lift installed by 4 Wheel Parts.
Running running 20x12 XF Offroad wheels on 35" Toyo Open Country II tires.

I'll do very little off roading but Daly Street driving. Since the installation of the lift, the truck rides much rougher on the street. I seem to feel every tiny little bump in the road now.

My friend has the exact same truck running 10 inch wheels but has a fabtech stage 2 lift kit.
​ his ride on the street is much softer and smoother.
4wheelparts4wheelparts says everything feels fine to them.
Can anyone confirm if the street ride should get stiffer than stock with a stage 2 Procomp 6 inch lift?

Also can anyone confirm if there is significant difference in the fabtech vs this Procomp kit?

Lastly does anyone know if I can return this kit?
I can't stand it!

That is the one with the coilovers right? The coilover is going to make a huge difference. From what I've read, those coilovers with the procomp aren't quite as nice as the dirt logic that come with the fabtech. Could be why there is about a $1000 difference between the two lifts.

Also yes, most off road shocks are a little stiffer on the road, they are made to take big hits at fast speeds and not break anything.

You could try getting a spacer and bilstein 5100's. That will behave a little better on the road.

Correct. Procomp coilovers. They have a large 2.75" single resivoir..
I've read the opposite, many times, of what you said. coilovers producing much better rides in stock even on streets. And struts with a spacer will make the ride stiffer... Correct?

can anyone confirm if the Procomp coilover is a stiffer one?
Also can anyone confirm what the softest coilover available is for a 6-inch kit?

Last, anyone know if 4 Wheel Parts has a Satisfaction gauranty? I really HATE my truck now!

If you go with a 2.0" coil over, they are more valved for street and slow off road. Those are generally a little more plush on streets.
The 2.5" coil overs are generally more valved for off road, and if you read icon, king, fox, etc. 2.5" reviews, a lot say they are more harsh on road but amazing at 35+ off road, which is their design.

Better ride is subjective, a lot say they do give a better ride due to other factors like less body roll, a more planted feel, no wandering, etc.

You could try lowering the coilover collar a little to not compress the spring quite as much. This will give you a little more of a plush ride with the sacrifice of front lift height. If that doesn't help, a spacer designed for your lift kit (the stage 1 option) and using your factory coil over will give you back your factory feel, that would probably be your cheapest option.

Sounds like you would have been better off with the stage 1 front lift like was said. Especially if you don’t really off-road it. Probably save you some money, too. I’ve got the Zone lift using the factory coil overs and it rides just as smooth as factory on the road IMO.

Also, are you using the coil overs to stretch the front lift? If so, that can hurt the ride quality, too.

I don't know if the coil is stretched. 4-wheel parts so they did not adjust it at all that just installed it as it came from the factory.

Are you guys saying that the stock strut with a spacer is a better Street ride quality (softer and more plush or cloud like) than with coilovers? I've always heard just the opposite.

There are many factors that can go into a coilover. A big one is spring rate, which the aftermarket is probably using a 650-700lb/in eibach spring (most do) compared to factory which I believe is around 450lbs/in. Then depending on the valving on how it allows the fluid to flow determines a lot of the characteristics of the coilover. I know bilstein's are generally are a little stiffer ride but I would consider them better because it fixes a lot of the looseness of the stock suspensions. I am putting fox 2.5's with dsc (Around $2k) on my truck here in another month and have read quite a few reports of a similar thing as the bilsteins. Same with Icon and king when I was researching. Now the 2.0's I have read that they improve street performance for the most part., but I am building an overland rig so I value the off road performance and am willing to give up some street comfort.

I don't know much about and have never experienced the pro comp coilovers, but when I searched pro-comp coilover reviews, the ones that actually talked about owning those coil overs complained about it being a very harsh ride. A 2.75" coilover for under $1000 (after coupons etc) doesn't breathe a lot of confidence in me that it is very good.

But again, I would try backing off the spring preload a little (if you can) and seeing if that helps, it probably will.

On my motorcycle (penske double clicker with remote reservoir) which has rebound and compression adjusters (Which control oil flow), I can make the ride cushy or as hard as I want by controlling that oil flow. It also has a spring that was selected for the machine and my body and gear weight. For more aggressive driving, I want it a little stiffer. For general commute, I want it a little cushier. But when I am riding aggressive I don't want to bottom out my suspension in a turn. That gets scary. My commute doesn't have me pulling fast turns so I am not worried about bottoming out as much.

Same with my my rzr with the fox shocks. Factory setup wasn't great. Spring rate was terrible choice and valving was off. I changed the springs to a dual rate setup and had the valving adjusted to match my machine and riding style. Now it is a Cadillac off road going over massive bumps. But On streets it feels a lot of the small bumps (the shocks are made to move throughout their range, not just a tiny bit), super loose from how I have it set up, and can be dangerous (I really limit on road for many reasons but this is one of them.) I also have compression oil flow adjustment and can make it softer or firmer by controlling the oil flow as well. I firm it up when I am going to be going over massive bumps and quick so it doesn't bottom out the suspension. When I am cruising slower speeds or flatter ground, I soften it up.

Moral is, it depends on how these are setup. Most 2.5"-3" coilover are designed to be off road beasts and are valved and sprung as such. They don't absorb little bumps well because they are designed to not bottom out on the big bumps but take those big bumps in stride and feel the same on big bumps as they do on little bumps. They are also that size (2.5"+) so they can hold more oil and not fade as quick as the oil heats up, also why reservoirs are used, more oil.

I’ve always heard coilovers ride smoother too unless they are stretched which puts the angles out of wack same as running a leveling kit which makes things ride rough. Maybe someone will come along who has coil overs and put in their 2 cents. I’ve heard the procomp lift is horrible for the loss of turning radius. If that’s true maybe their are other issues with it...

Pro Comp runs a 2.75 coilover. I bet that is why it is running rough on the street. You could of saved $1000 and did the stage 1 kit.


Also what PSI are your tires set at? That could make a difference.
