1988 Chevrolet G30 Hi-Cube 8 Cyl 6.20L

Transmissions & Drivetrains

What gears were originally put in the cube van?

Trying to change out the ring and pinion from a 410/411 gear to a 373 but no luck have tried 6 different gears and cannot get any to fit. It is a 1 ton 14 bolt cover on the rear end with a 8 lug axle.

Thtree (3) different rear axles were available for the G30 1 ton;

GM 9.5" Rear, '79-'97 = gear ratios = 3.42 to 5.38
GM 9.5" Rear, '79-'97. 14 bolt rear with 9.5" ring gear. Has 33 spline c/clip axles. No removable pinion support on the front.

Dana 70 U - (35 Spline) = gear ratios = 3.54 to 7.17

GM 10.5" 14 Bolt Truck, '88 & older (excluding '84-'85) = gear ratios = 3.21 to 5.38
