4:56 gear sets, front and rear, with master install kits from Jegs. All new in box. $550.00 obo

Gears fit the following as long as you have gears lower than 2:56s:

77-87 K10/K20 (front), 77-91 Blazer (front), 80-02 C10/K10/Blazer/C1500/K1500 (rear), 80-96 Suburban (rear), 77-91 Suburban (front)





I do see you will need the proper front gasket.
