4.88 ratio "Super 60" ring and pinion sets bolt right into RockJock® 60 or standard high pinion 60 housings and provide you with a 10" ring gear! These gears fit the 4.30 and up ratio style of carrier. Be aware - if you have a RockJock® with standard reversed rotation 60 gears and carrier in it already - it has a 4.10 & down carrier in it. This makes these gears not a direct swap without a carrier replacement!
