Inner fender liners for diesel?

[fourfa]

Diesels (and 392 Wranglers) come stock with longer jounce tubes than the 3.6, I guess because the oil pan sits lower and the factory saw fit to limit uptravel a bit. So if you see a particular lift kit saying you need to add 2” of bump stop, usually they have no idea that diesels already come with that extra 2”

I have 37s on stock fender liners. +0.5” bump stop in front (because I cycled it with no springs or shocks and determined exactly how much I need with my frankenlift - and it’s to protect my longer-than-stock shocks, not the liners), and have never rubbed the liner anywhere in front. +1.5” bump in the rear (mostly to protect the bed sheet metal from my aftermarket swaybar setup) and the tire kisses the liner just a bit but only on the very hardest crossed-up trails with two wheels dangling in air. NBD, no reason to do anything about it. It probably goes away if I center my rear axle a bit better in the wheel well at full stuff

I’d advise to build what you want to build, cycle it, drive it, see if there’s a problem before spending more time worrying about it.

Yep, that’s exactly what I plan to do. Thanks for the details. Sounds like your setup works really well. I guess I’m surprised it doesn’t rub in the front. I was planning to cycle mine with no springs & shocks as well. That’s the only way to know how to set up the bumps without leaving up travel on the table.

I see you have a Rubicon so wide track axles. Just for my own research and comparison, what wheel specs you running?

I saw your other thread on bumpers too - I have a Mopar-style full width bumper (MP Concepts aluminum) and I’ve seen no need to take the side extensions off. Rather, they don’t contact the 37s at all. They do sometimes contact the ground on extreme trails.

Yes mine’s Rubicon, and these are Icon Rebound Pro (quasi beadlocks) with -6 offset, or about 2” more than stock. And 12.5” wide tires. So yeah, that’s a fair bit more spacing than a Willys (but also more tread). I probably don’t need that much offset but the Rebounds didn’t come in anything less

Much appreciated. I will eventually go 40s if I don’t just go straight to it… so the stubby bumper is gonna happen one way or another.

Big issue with the diesel is the windshield washer fluid bottle is on the left side and interferes with some of the aftermarket inner fenders. I have the American adventure labs fenders which are amazing, quick release. But I had to change the windshield fluid botttle to a smaller version to get them to clear. Motobilt makes a kit but it’s expensive. I just bought a smaller tank and swapped the neck and motor over. I am on about 4 inches of lift and 40s with 72.5 inch wide fusion 60s, clears at full turn and suspension cycle.

Yeah, I noticed the washer fluid reservoir there and figured it was an issue. Had the same idea as you: get a smaller one. Then googled the cost of a relocation kit. Returned to previous idea: get a smaller reservoir.

A few questions…

So the only reason gas model inner liners don’t fit is the washer fluid reservoir?

Do you mind sharing your wheel specs with me?

Which flares are you running?

Trying to avoid buying some parts then then having that moment of ahhhh &#@$ this doesn’t work together or I need more parts now. Thanks.

I love my set up. Have Bilstein 5100 shocks right now. Planning on changing them with a black Friday sale. Want Ohlins, but they're a bit pricy. I want something that is adjustable.

I haven't seen ohlins that were available for the Gladiator yet

I have the KMC desert beadlocks 4.5 inch backspacing and 40x 13.5x 17 Pats, going to Nittos soon. I have the stock rubicon flares but split them to gain the extra clearance and did the American adventure labs fender lights. Definitely cheaper just to get a different bottle, like 25 bucks and Mount it in there.

Thanks! I will probably need to split my OEM painted flares since they are Sport/Willys. I wanna get all the up travel I can, assuming the shocks aren’t the limiting factor. That’s why I will likely need new inner fender liners. Once you split the stock flares I don’t know if you can re-use the factory inner fender liners. I’m sure there is a way, but if it’s more trouble than it’s worth and if coverage sucks… aftermarket is a better option. I guess I’ll have to F around and find out.

There’s also a simple option, use zip ties to pull the stock plastic up higher with a few strategic slits where needed

There is a couple of places that handle them. But you have to call. They're between $3700 to $4100.

I’ll probably do this to begin with, especially if I purchase one of those overpriced as hell fender chop bracket LED kits. Why the hell do those cost so much??? For the price of one of those I could nearly buy some KBD flares, all four, that also include LEDs.

Go straight to it! Sorry, I am a horrible influence.

But also, when I first lifted, I kept my original fenders and inners for 6+ months. I never rubbed, full lock or not, on my original setup of 17x9 and 40's (no spacers at the time).
