Is Richmond making those again? They hadn't been available for years.

They were and one other company i dont recall. There was info on pirate and jko if i recall. It wasn't to long ago i saw them, but never called to see on stock so may be all backordered.

Just researched. Looks all backordered, but some available on small timer online shops like the ones you find on amazon or google shopping.

If you Google the richmond part number you can find them for sale. Jegs has some as well as others.

I think the biggest difference in MPG between 2 similar vehicles ... is the way you drive it...

PD: The stock plugs aren´t supposed to be iridium ?

Also look at where they live compared to you, high altitude with lots of hills/mountains or sea level with totally flat roads. Or all in town/offroad compared to a long daily commute at 80+ on the freeway. It can all make a difference in the replies you get...

Ugh!!!

For the last week I've been saying 5.38 vs. 5.86 (leaning 5.86) when what I meant (and originally researched) was 5.13 vs. 5.38 (leaning 5.38).

I'm a dumbass, it's been a long week. I swear I've read too many gearing threads and I need to sit back and take a break.


I'm at 6500 ft and play on big rocks every weekend. Yes, I did wheels before gearing and armor and that's not ideal, but I understand the risks and know pretty well the limitations of my vehicle. I'm taking it easy with my current setup because my wallet is empty. In a few weeks I'll be regearing/artec front truss&guss/and possibly bjs. I'll be out of town for the next couple weeks here and there for work and vacation.. so it's one thing after another!

I really do appreciate everyone's contributions, it helps me a lot.

When I got my jeep I wanted the best mpg's I could get. So naturally I stuck to slow acceleration and watching the street lights like crazy so that I could always shoot right through them. I got sick of driving like a grandma so I sped up the acceleration a little bit and found that I got much better mpg's. I went from 12mpg to 14-15mpg. However it is a very fine line. If you accelerate to fast it will go down and if you accelerate to slow it will also go down.

Glad they went back into production. That ratio in a d30 isn't for everyone, but for the few who would want it, it's good to have the option.
