I had the 20% TJ gears...went well... BTW be prepared for drive line breakages once you got to 31s and a locker or 2... |

I have pushd the firewall quaters back on both sides, and cut into the sills. Is being welded up now and shouldbe finished today. Still searching for a nice set of flares to suit, then will cut the guards as necessary. |

think 24% would be too much IMO vvts got 20% and if Im not wrong they still end up doing 4000rpms at 100Km/h (from the 3000-3200 factory) non-vvts already do 4000rpms from factory... so adding even more reduction would be crazy for highway driving.... go for the sierra transfer case |

BertZook, when you say VVT's got 20%, I assume you are referring to the Transfer Case High range. This is true but the gear box is also different, which compensates somewhat. I have done very similar... 32" tyres with an Auto VVT case in my manual Jim. It does just over 4,000 at 100k's so yes it is a bit high but bearable and is a reasonable tradeoff for the offroad benefit. On Sierra cases, I can see no benefit in that because all Sierra cases are lower ratio in high... 1.409 and 1.580, so its actually worse. Add a gear set and it doesn't get any better. |

I should think it would go ok. The gearing would still be better than stock. No powerhouse but able to crawl through a lot easier. |

My last Jimny was an M13A, it had 24% reduction gears and 235/75R15s. It ran really well in the bush and around town but highway driving was tedious. Running 31s with 24% gears would be great all-round in my opinion. |

I'd imagine a M13 would be better than a G13BA, and it's just fine with the carby

I see your running 235s with 2" lift and 15mm spacers. Much scrubbing? Cheers |

I get annoyed when I do more than 4200rpms... I would go crazy with 5000.... plus bye bye fuel economy and yes Im talking about Hi range... either way this trialjimnys kits affect hi and low at same % |

Also if you're wanting 31's and reduction gears on a Jimny.. Maybe it's less of a road car than you want it to be and you could maybe sit on 80-90 on the freeway? |

I got 31's with a g13bb motor, at 100kph I sit on 4150rpm. i have the 24% reduction gears. I use mine as a daily and I like the setup. Whenever I go on the highway I only sit at 100kph it feels comfortable at that. |
