Dana 110527 Differential Side Gear

Dana / Spicer 110527 Side Gear – Differential Side Gear (18 Tooth, 41 Spline)

The Dana / Spicer 110527 Side Gear is a genuine OEM differential side gear designed for heavy-duty Dana Spicer single- and double-reduction drive axles used in commercial trucks, vocational vehicles, construction equipment, and off-highway machinery. As a critical component of the differential assembly, the side gear transfers torque from the differential case to the axle shaft while allowing the differential to compensate for differences in wheel speed during cornering.

Manufactured from heat-treated alloy steel, the 110527 is engineered to withstand the extreme torque loads, shock loading, and continuous-duty service found in heavy-haul and severe-service applications. Precision-machined splines and gear teeth ensure proper engagement with the axle shaft and differential pinion (spider) gears, promoting smooth power transfer and extended service life.

The Dana 110527 is widely used in numerous Dana Spicer axle families and is a common replacement component during complete differential overhauls or axle rebuilds.
