Readylift 2.5" Spacer or Coils?

Been researching a bit and think I'm narrowed down to Readylift. Seems quite a few on here that are happy. But I see they off the 2.5" on a spacer OR a replacement coil. My truck is a highway brawler towing a 30' 12k lb trailer. Which setup would ride better?

I did lots of research on this and there is no one with experience regarding the springs. Readylift could not supply me with the spring rates but told me it would be rated for the lowest factory spring rate. I plan on being the guinea pig by doing the springs when the time comes.

Since we are talking about a level and not a full suspension lift, you would think replacing the coil would be the better way to go.

So before I pulled the trigger I thought Iíd call Readylift. The rep recommended the spacer for two reasons. 1) The ride will be better and 2) the full coil will settle down over time and not provide the desired lift.

Suprised to hear this recommendation from the manufacturer but since I had the spacer kit on my last truck w/o issue I decided to go for it again. 20k miles later, no regrets. Great ride and aesthetic. Good luck!

I spoke to Carli about their 2.5 inch level coil. What info are you looking for? I currently have a 2 inch BDS spacer. Carli claims their coil is going to be a better ride than a spacer and I can't find a reason to disagree.

That IS interesting. Wonder if I call will they say the same thing? I don't mind the stock ride so Im leaning towards the spacer.

The Carli seems nice, I'm just trying to justify all the $ for 2" of lift. My 2007 I bought an Icon 4" for all the $ and I wasn't impressed.

This may explain it, A "better ride" means softer springs, read less capable springs. The truth is spacers will NOT change you ride, your have the exact same suspension, your truck body just sits 2.5" or whatever higher. Most, if not al,l of your pre-made life springs are built for a "smooth ride" because this is what most of the customer want. Of course, you can go to a custom spring manufacturer and they will build you anything you want, Deaver and National Spring are two that come to mind. However, obviously, the custom route is more money than the mass produced route. The real difference is the articulation and spring travel given these are heavy trucks and not rock crawlers 99.99%, should be 100% but there is always that odd ball out there, of us do not care about articulation.

For the money, time and effort, I MHO spacers are the way to go for this application.

I agree - spacers. I have them on my truck and I hade them on my F150. Theyíre consistent and maintain the factory ride. Do get caster bushings and do get either the trackbar bracket or an adjustable trackbar. Youíll need both to maintain geometry.

I thought the complete spring replacement would be the way to go for the simple fact itís less parts. Thatís why I always replace shocks and toss the extensions that are included.

Also I second that remark on the castor shims. Below is what Iím using and the alignment after was a breeze. Getting the old ones out was the trick.

The Carli springs are multi rate ..... so are they "softer"? I don't know. But since Carli only offers 1 coil rate I guess it could be softer or stiffer depending on what coil springs you currently have. I cannot find a spec on them on the website so can't tell for sure without emailing them. I'll update with their response.
Carli's response when asked for the coil affect on load capacity: "Front coils don't affect load capacity, only rear leaf springs. Ours are a reduced rate but load capacity is unaffected"

Not sure what to make of that.

I have rear adjustable Fox 2.0's already and my plan was to replace the fronts with this also. Thanks for the link!

I've been considering the same option. Spacer or new coils. I currently have the snow prep springs. With my research of ICON or carli springs they are a dual rate where the initial part of spring is for your some bumps to give you a smoother ride and the secondary part of springs is for your pot holes. My thoughts are springs as the ride would improve over my stiffer snow prep springs.

I didn't want to risk the ride to an aftermarket co's interpretation of the factory spring. So went with the spacers. No issues.

Carli springs in the 2.5" variant are linear, not progressive. Their 4.5" springs are progressive. BUT, the Carli springs were a pretty big improvement in on and off road ride. They are much more linear in their compression, smoother while still being firmer. It feels like I have more control up front, especially on hard bumps at speed like on the freeway.

The Carli springs are only $315, its really not that much money when you think about it. You can buy your own shocks, and you can get your sway bar and bump stop spacers from anyone that makes them, you dont have to get the Carli branded ones. You'll have a better ride and you'll have more travel.

I look at it this way, every single time you drive your truck you'll feel and experience that $315 you spent. Its a $60-80k truck, whats a few hundred bucks on something that is so important to the quality of your ride every time you hop in it?

There's quite a big difference in the springs, the stock ride wasn't bad at all. The improvement per dollar though with Carli springs were worth every penny to me however. Just looking at the spring I think you can imagine the difference in ride.

Couldn't agree more with Tricon. I'll be going the 2.5 route and hope I have a little rake left as I tow often.
