"Pacing myself" build

Another one of my cockamamie ideas is rattling around in my head again. I've been measuring my uptravel and how it relates to my overall ride quality as of late. After doing the ziptie test, I average about 3.25" of uptravel during normal DD and typical road events such as pot holes, and mountain road driving. My current setup allows 4.5" of uptravel, however, 1.75" of that uptravel is taken up by the jounce bumpers. So, if I do the math, I'm hitting the jounce bumpers most of the time just during normal everyday commuting road events. Now I know the jounce bumpers serve a very important purpose, and it gets me thinking of all those threads I see of folks complaining about ride quality. In my situation, there is only a couple things I can do,
1. Raise the suspension height up more.
2. Remove some bumpstop.

Removing bumpstop is a no go unless I run a smaller tire. Not going to happen anytime soon.
I really don't want to raise it much higher than it is now, but I am thinking about new springs since mine are getting long in the tooth. I'm considering going with 3" front/2" rear springs. If I go 3"/3", and have a rake I don't want, then I end up spacing the front to level it, and in turn raise it even more. If I do 3"/2", and the jeep sits even or a little low in the rear, I can space it to level out and not be raising the jeep more than 3". Either way I'd end up needing to use coil spacers to get the ride height I desire. Nature of the beast.

Another thought I had was to trim the jounce bumpers .75" so as to not be always hitting them as much. Not sure if that is such a good idea. @jjvw , I seemed to remember you dabbling with the 3"/2" setup. Thoughts? My end goal, 3" of lift, 5" of uptravel, and not hitting the jounces at 3.25".
Also would like to find a 2" rear spring with about 150 in.lb. spring rate. My OME 942's are 160 in.lbs., and while they work well when I'm loaded down, 75% of the other time I'm running light as a DD. Thoughts?
How much bumpstop are you running on your current setup?
 
The jounce bumpers are so soft I couldn't imagine them causing any significant concussion if you get into them.

In all my spring combinations, I've kept both ends pretty even.

If anything, trimming the jounces might let you use a bit more travel on the everyday hits, but you'll feel the impacts of hitting full bump more. As an test, maybe remove the jounces and see what happens.

With your bumps being only as long as they need to be, I think the only way you get more up travel is to add clearance in some way.

I have 6"/7" of up travel. Using the zip tie test, I'm typically well into 5" on the street. More if I don't slow down for anything.

Regarding the spring rates, if you can find a 150 lb/in that provides the same ride height as the 160lb/in, you won't feel any difference. It will be the same difference as 20 lbs of cargo. Keep in mind that a tank of gas is about 90lbs. If I'm close paying attention, then I can feel the slightly softer ride after leaving the gas station.

I like the stock fender look, so that won't change. Maybe some trimming can be had, I don't know.

Still undecided on which springs to get. I only have experience with OME, so I might go with 941's rear and stick with 933's up front and add 1" spacers to suit. I'm not afraid of trying BDS or Procomp, but their spring rates are a little high for my light jeep. Rancho had a spring that I liked but those dillholes won't sell just their springs. Idiots!

I wish I could get onboard with aftermarket fenders, but I love the look of the stock ones so much that I'm willing to give up some function for form.

Pretty much where I'm at now. It's the price I have to pay for going to 33's. Still kicking myself over that one.

Fenders.....fenders....fenders! The original Jeep had flat fenders. You'll be more Jeep if you go with some. MCE has a fender that has the same OEM finish as our stock (+ 2" upper clearance). There's your answer. I just didn't provide it because I know you don't like it. But now that fenders are on the table....

The only beneficial fender options are MCE, Metalcloak or hi lines.

This pic shows exactly why regular flat fenders don't accomplish anything. In fact, if the lip is larger than that factory cut out, they will reduce clearance. Jeep really made the most out it the old CJ platform when they built the TJ.

Meh! @JMT.

buddy of mine did the MCE thing. I just couldn't sign up for the look, although the function of them cannot be denied.

I just can't bring myself to do this,

I'm still unsure about the aesthetics of MCE. Especially where the fender meets the hood. I think the darker the body color the better. Or paint them to match.
 
I like the flat fender look although the cost makes it prohibitive for me at the moment. If I crash my fenders and have to replace them I may go that route. I do like the stock fenders but hate the turn signal in it. I always have. If I could get someone to fill it and paint it cheap enough I would run JK blinkers in the grill and cover the fenders. All of that said I have always been a fan of the flat fender jeeps.

I am still deciding if I want to get rid of my spare springs or not. They are the lights, and I believe the 941's although I don't have them in front of me. They are practically brand new; were on the Jeep about two months. (rears only)

New springs are down the road for me, so if you ever decide to off the 941's, I may take them off your hands. When I say down the road, probably next year. Hey, you can bring them to Moab and save me shipping, lol!

Yeah that is perfect because it gives me plenty of time to decide if I ever want to go back to them. I am pretty sure if anything I will go to currie some day rather than go back to those, so you probably have a deal.

Buy some used from the junkyard, as long as any damage is outside the inner portion you need to connect the flares, you could get a deal, cut them and mount some MCE's, and save your original fenders if you hate it.

That is an option if I could live with how they look.
 
C'mon....You know where this is all going...Body lift! I'm actually surprised at how much bumpstop you have to run, based on 3 inches of lift and a half inch body lift. I'm running 32" tires, with a 2" spring and 1.25" BL and I only needed 1" in the rear and 1/2" in the front. So an inch less tire (half inch for the purpose of clearance) 1" less spring lift and .75" more BL. Net is I only have .25" more clearance (due to more BL and Smaller tires) but you have significantly more Bumpstop than I do. Curious...are you bumped based on clearance or shocks?

Yeah, it's all going back to butt crack! Of course, I love how you hid your's. Need more butt crack @bobthetj03, 1/2" won't cut it.

On mine I'm running 1.75" bumpstop with 2.5" OME in front and rear and a 0.75" spacer up front to level it out and 1.25" body lift. I'm right up to the fender at full stuff.

Yeah, we all know you like butt crack buddy, lol!

Technically, my suspension lift is only 2.5", so with my 0.5" BL, I'm only sportn' 3.0" total clearance. With the newly added BL, I could probably shave 0.5" of bump up front, but at that point my shocks will be the limiter.
