I stopped by my dealer yesterday to take final delivery of my truck and it wasn't ready. No big deal, but I noticed the leveling kit they installed was a 3" Pro Comp, not the 2.5" Readylift I requested.

First off, I think the front-end will be too high. But if it is level, what do you think of the Pro Comp kit? It's a 2 piece design that compresses the spring about 1" and adds a spacer on top of strut. My concern is adding preload to the spring will hurt the ride comfort, which is a big deal for me.

For those of you with a 2.5" Readylift, what is the part number?

What do you think?

 

curious about this too, my dealer works with an offroad shop for aftermarket, and they are only offering me the 3" procomp. I'm sticking with stock wheels/tires for now and thought that a 2" level would look ok until i upgraded tires. I'm thinking 3" with stock will just look wimpy...

 

The only time the spring is preloaded is when its out of the vehicle and the thicker top coil spring piece is installed. When its in the truck the spring is compressed to the exact same length by the weight of the truck. The shock shaft is extended to a different neutral position by the thickness of the new piece on top of the coil spring, thus you have different shock travel range, that's it. I don't know of any advantage to a 2 piece kit, a lot more work to install.

 

how does it look?

 

The 2" Procomp lift that my dealer installed didn't change the ride at all. The rear is 3/4" higher than the rear. I have 3" blocks from Autospring I'm thinking about installing. I am a fan of more rake.

 

Please if you can post some pictures of your new purchase. You can find out if they did install the Pro-Comp 4WD Strut Spacer, Part # 62206 is a 3” Leveling-Kit. They didn’t install the Ready-Lift T6 Billet 2.5 Leveling Kit Part #: T6-2058B Part Colors: Black, Red & Blue. Fits: Ford F 150 2WD 2015 ONLY.


Because is made for 2WD only…

 

I wouldn't worry about it. Truth be told, they achieve the same goal. If the dealer will warranty the truck, I'd be okay with any of the major manufacturers.

 

Not true. Once you've moved the end points for a spring closer together you've altered the spring response. A spacer between the shock body and the spring is creating a preload situation. The shock shaft extends fully whether you are using a stock spring or a spring with preload.

 

Do you happen to be located in South Louisiana?

The dealer I bought my truck from installs only ProComp, reason buying is that the ProComp is sold by a dealer that Ford has a contract with and its the only one they will warranty if they do the install.

Not sure if it's true or not but that's what the service manager told me.

Also, ReadyLIFT had issues with the studs cracking. Mine broke 2 studs in each side. A friends truck broke 2 on one side and the other had 1 broken stud.

They did redesign the studs and neither of us had a issue since swapping them out.

The bad studs have a allen hole in the top to install it. The new ones don't have the allen hole.

Yes it is true, a lot of people think its preloading the spring but its not. Its only preloaded when its out of the truck. The end points of the spring are exactly the same distance apart when its in the truck before and after the spacer. What do you think is compressing the spring? The weight of the truck. Look at it this way. Put a spring compressor on the spring when its in the truck, just snug it up so the spring stays right at the same end point distance. Now jack the truck up take out the strut. The shock will creep upward on its own with the end cap until it tops out. You can take the nut off, cap off and "drop" the spacer down to the spring, NO preloading. You can't really do what I just said because you can't get a HD spring compressor in there, just makes visualizing it easier. Another way to see it is get an ink pen with a spring in it and play around with it.
Not many manufacturers use 2 piece anymore but the ones that do will claim no ride difference from stock. Which is true because there is no "preloading". If your spring was really preloaded, end point distance shortened by 1", you would have a stiffer ride.
