Install 4 88 Gears In Dana 35 From 4.10 || Jeep Mods E15

Installing 4.88 gears in the Dana 35 for our Jeep Wrangler with a 2.5L, how we did it and what to expect during the install. See the tools and parts used for this install below. Now everyone says you should just go with a bigger engine, there is no replacement for displacement, we don’t think this. When you are on the trail turning moderate size tires, going slow helps, give you that extra time to think about the stupid things you may get your jeep stuck in.

The whole reason for this ring and pinion change was to improve the road performance of this YJ Jeep Wrangler, the offroad crawling is a plus. This Jeep has 32-inch tires and with that said 4.56 would have probably got it down to like the factory on the speedometer. With the new gears, the speedometer is 5 miles slow at 55 MPH, but the power is awesome. We can drive uphill at speed in 5th gear now with no issues, and if the hill is gentle, even gain speed. In 4 low the crawl speed is slow, we’re talking you can get out and walk much faster than the jeep.

We hope this helps you with your dana 35 install, and most gear changes in the GM 10, GM 12, Dana 35, or in most axles are the same. It is the shim points that differ and crush shim or fixed shim in different differentials. This is not an easy project, and not having the right tools can make it very hard to impossible, plus you can destroy your new ring and pinion.
