So, I just picked up my Rubicon this evening from a fellow named Dan with Dan's Gears. He's located in Sherwood, Oregon and has been doing nothing but gears and ring & pinions for the past 35+ years. If you're local to Portland I can't recommend this guy enough. I dropped my rig off on Sunday evening and he had it done the next day (Monday) at 5 PM!
Anyways, he was installing a set of 4.88 Revolution ring and pinions for me in the front and rear of my TJ Rubicon. The stock 4.10 gears were not cutting it with 33" tires and the ridiculous 0.69 overdrive that is infamous on the 42RLE transmissions.
Upon getting in the Jeep for the first time after picking it up this evening, the first thing I noticed is how much better the Jeep goes off the line. After several stop lights it was immediately noticeable that it had a lot of low end power. Climbing up through the gears to the highway speeds where I spent a good 15 minutes, I noticed that the transmission no longer seems to be hunting for overdrive (thank goodness!).
What a totally worthwhile upgrade! The power that I had seemingly lost from going to 33" tires is now all back! It feels just like stock again, but with bigger tires! I'd been so reluctant to re-gear the Jeep because I didn't think it would make much of a difference, but boy did it ever!
Dan did a damn good job of installing the gears. No whining, no weird noises, just smooth power to the ground. In addition to that the quality of these Revolution gears (which are some of the only gears still made in the USA) is amazing. I'm more than impressed to say the least, and they go well with my 4340 Revolution chromoly rear axles.
In conclusion I highly, highly recommend Revolution ring & pinions. If you read around, you'll find that these are widely regarded as being some of the best ring and pinions on the market.
Also, if you are in Portland, Oregon and need someone good to do your gears, be sure to call Dan with Dan's Gears. This guy knows his 4x4s inside and out, and he does nothing but gears!
