1977.5-1991 GM 10 Bolt 1/2 Ton Front Axle Introduction
Page 2 of 20
GM introduced the corporate, 10 Bolt, 8-1/2" Ring Gear, beam type solid 4x4 front drive axle during the 1977 model year. The new axle was available for higher speed gear ratios than was the Dana Spicer Model 44 front axle which GM continued to use for certain ratios until 1980. Although the differential parts are totally different, the 1977 to 1981 GM Dana 44 and the GM 10 Bolt front axles share a lot of common parts from the axle u-joints out to the hubs. The GM 10 Bolt front axle was used on Chevy and GMC 1/2 ton 4x4 pickups from 1977 to 1987 and on Blazer/Jimmy, and Suburban SUVs from 1977 through 1991.
