Toyota trucks and 4Runners use 7.5", 8" and 9.5" ring gears, plus a few oddballs. Check our list to match the gearset to your diff before you buy.

We are only looking at ring and pinion sets, not differential housings. Make sure to check out our Toyota axle information and also the links at the bottom of the page.

About Mike Johnson

Mike came out of the womb with a Birfield in one hand and a stick of 6010 in the other, ready to weld any piece of trail-busted steel back together. He has wheeled, broken, and modified a variety of rigs, from Toyotas to Jeeps to Fords to Chevies. He likes doing long distance overland travel and would happily spend every night in the bed of a pickup under the stars.
