Re: need advice 1995 wrangler 4 cylinder safe rpm spee
If it is a stock 94 and the axles have never been changed, then you have 4.10:1 R&P. That is what all 4 cyl YJ's came with. And I am guessing it has factory size tires on it. Mine was the same way when I got it, and I felt the same way. I didn't like how high it reved. But it is normal, that is the power band.
My solution for the high reving was to put bigger tires on my jeep. I went from 26.5's up to 30X9.5's and it was WAY better. I felt much more comferdable with the rpm range. However there was a small loss in power. But I felt like the 30 were perfect. To make them fit, I added a leaf to all 4 corners.
Then I went with 33X12.5 in tires. And the ratio still didn't really bother me, but there is a real lack of power with a 4 dinger, and 33's. But I live with it. Next my Jeep will see 4.10:1 R&P, SBC 350 and 37" tires. I can't wait.
