GM 10-Bolt Front Axle Spline Count? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

trukman1 · 02-24-2021, 12:30 PM

My '88 K5 8.5" 10-bolt has 28-spline rear axles and so I'd think it has 28-spline fronts as well.

Later Gm went to 30-spline axles in the rear.

My question is did they have 8.5" 30-spline front axles as well?

I tried researching internet but can't seem to find anything on this.

Any ideas?

Thanks in advance...

Yes 30 spline fronts were available in the Suburbans, easy to convert to if you wish
