5.12\'s and 33\'s?

Will my Samurai rev high on the highway with a 4.16 t-case, 5.12's axle ratio, and 33" tires?

Billybob ran this set-up too. But I think he had a stock t-case.

All I need to go is 50MPH, But I dont want to be reving 4500RPM, 4.62's are not that much differnt though?

Re: 5.12\'s and 33\'s?

hey man, when i had 5:12s and stock t/c, i was turnin about 4200 rpm to run 80 or so. when i got my grsII, before i puked my 5:12s, i could run approx 50 or so and not twist the motor too hard. although i did have it up to 70 once on the interstate.

Re: 5.12\'s and 33\'s?

It's not that bad.... I have a GRSII, 5.13's and smallish 32" SX's.[img]/wwwthreads_images/icons/shocked.gif[/img] I realize my speedometer is way off, but judging from the flow of traffic I would guesstimate that I'm doing around 55-60 MPH at 4,600 RPM. You'll have absolutely No trouble pulling hills in fifth gear! I pulled a small utility trailer today with two lawn mowers on it, uphills were not a problem.[img]/wwwthreads_images/icons/wink.gif[/img] The revs are a bit high for a daily driver I guess, but for a rig that is used mostly off-road, low gears Rock!

Re: 5.12\'s and 33\'s?

I agree with CSR, the gearing is worth the revs. I run a GRS1, 5.38's and 32 BFGs. If I remember right, my speedo says 70 and the tach is around 4400rpm. The speedo is about 14mph off. I used it all last week because of gas prices. With all that gearing, it still got 24.2MPG in town. I dont know how true that is because of the tire size tho.

YEAH BUT 5.38'S AND A GRS 1 IS A SET-UP SOLED TO RUN 35'S SO 32'S SOUND LIKE HORRIBLE HIGHWAY TIMES!!??

P.S. IT WOULD PROBABLY BE QUICK CITY WISE THOUGH!

Re: 5.12\'s and 33\'s?

It will rev high at 50MPH, but it's not too bad. The thing I notice is that you go through the gears fairly quickly. I often don't even use first gear because it only takes ten feet before I need to shift into second.

I am running 5:12 and GRS 1 with 32" tires and it screams like a baby at 50 but I tow it so it does not matter.
