GM 8.5" 10 Bolt Posi Limited Slip Package – 3.73 Gears, 28 Spline, For 1970-1998 Chevy/GMC Trucks & Cars

Got a GM 8.5-inch 10 bolt rear end that needs some traction?

This limited slip posi package from Rigid Axle is a direct fit for a ton of GM cars and trucks from 1970 all the way through 1998.

It's set up with a 3.73 gear ratio and 28 spline axles, so you're getting that perfect balance of off-the-line punch and highway manners.

Everything you need is included—the carrier, gears, and all the mounting hardware—so you can get this swapped in without chasing down extra parts.

It's built tough to handle some abuse, whether you're hitting the track or just want better grip in the rain.

Six-month warranty gives you a little peace of mind too.

If you're tired of one-wheel-peeling everywhere, this posi kit will put the power down where it belongs.
