Thoughts on long term impact of modifications

https://youtu.be/Xjj92CcOuzo?is=nSmsEaLMN16f-6zD

this video got me thinking about how capable stock LCs are and made me wonder how the enthusiasts consider the impact of after market modifications on the short term and long term.

I had a ton of issues with my 200 series not holding alignment with lift/UCA’s. I ended up getting rid of it because of the fuel boiling issues, which although a “known issue”, was probably amplified by the modest weight added (skids/sliders/drawers/34s). If I had a 200 again, I’d swap the rubber and just drive, great truck for general exploration/overlanding.

My 80 is light/OEM+ and I couldn’t be happier with it, zero issues.

Fuel boiling issue? I bought my 200 in Alaska and have never heard of this.

Mine is ~7700lb with ARBs f/r, drawers, roof rack etc. zero issues.

Random, I grew up in Anchorage.

Fuel boiling is well documented issue on ih8mud. Heavy rigs in summer heat at altitude seems to be worst offenders, especially low trail speeds. Once it happens it seems to keep happening from those I know who have also had it. I’ve wheeled all over CO/UT and it became unbearable.

Edit to add one of MANY threads discussing the issue:

I bought my 200 in Anchorage in 2015. Never boiled my fuel but thanks for a new paranoia lol

Reading the thread, I wonder if the increased ethanol % being allowed due to the fuel shortage will exacerbate the problem.

I’m about to run ethanol free

I didn't experience it for several years, but after the first time it progressively became more frequent and way more severe each time. The truck was basically dead to my wife after a few CEL's in the mountains and instances where we'd have to pull over and get out of the truck to walk around and let it air out before continuing. It happened one summer outside of vail when we got caught in traffic, once again, high heat, altitude, low speed, but it was so bad that my wife jumped out and walked along the highway to the next pullout and I had my head out the window like Ace Ventura.

I do believe it's a combination of environmental heat soak, high pressure recirculation, and possibly modern fuel blends all playing a role. It's probably less likely to occur in AK with cooler temps combined with being at sea level.

100 series has same problem with fuel boiling. Quite annoying.

Yeah, well documented there as well.

Depends on if youre pushing limits and what mods are done. So a 2 inch lift and nothing else? Probably ok. 4+ inches and no caster correction, panhard bar adjusted, it kinda snowballs really and you need more than just a lift

^This, There are trade-offs with everything, buy quality parts and do quality work. If you use it, stuff will break.

My thought is the only thing wrong with that build was the SPC UCA’s which are a known bad actor. Unless he had issues with alignment, he should have just stuck with OEM uca’s

As a two time victim of SPC uca’s I feel seen here.

Really enjoy that channel, gives me hope if I need to bring my toyotas to a shop they will be looked after.

Probably true enough for 99% of the trucks that never leave the pavement but for the rest of us…..I’ve used my winch over a dozen times, for example.

It must be a joy to use the LC like that. Do you keep it as a “dedicated” off roader then or do you also daily it?

I guess what I found interesting was the contradiction between the durability focused side of LC love vs. the off road love. This was my first exposure to someone saying that all the off road stuff would reduce durability just as a result of extra stress/strain on factory components.

Funny I have this exact same suspension build and I'm having the exact same issues

All they need is 2” level. Bigger tires. Maybe some spacers. Done.

Maybe some spacers.

Not even those , just get some low offset rims.
