Aftermarket Performance
High Strength
Designed to withstand the forces of high horsepower, Yukon Gear Ring & Pinion Sets bring trusted performance on the street, at the track, or on the trail.
Bigger & Better
Upgrading your differential gear ratio is a requirement when increasing tire size. Selecting the right ratio will lower engine RPMs, reduce breakage, and help your rig conquer obstacles more easily.
To Calculate Your Gear Ratio:
[ (New Tire Size / Original Tire Size) x Original Gear Ratio ]
For Example:
[ (37" / 31") x 3.73 ] = [ 4.452 ] = [ 4.30 or 4.56 ]
Improved Towing
Lower the stress from towing and improve gas mileage with an aftermarket gear ratio upgrade.
