    I have a 1990 c1500 chevy truck 10 bolt. 1 wheel tire burner will this help

    Asked by: Wwt6666
    Thank you for your question. A Lock Right replaces your Open internals to create a mechanical locking differential. Part# 1920-LR(28spl '70-'87) will not fit in your 1990 truck since after 1988 the GM 8.5" differential used 30 spline axles shafts. Part# 1921-LR(30spl '88-'98) will fit your application.

    Asked by: redneck65
    Thank you for your question. The Lock Right locker replaces your open/standard internals to create a locking differential.

    this will not affect drive ability on the street and can different gear ratio be used

    Asked by: Hotrod 72
    You will notice a difference in how it drives but not negatively. A different gear ratio can also be used with this.
