The GM axle is on the bottom. They look identical other than the boot configuration. I hope to order my seals in the next couple days and plan to install them in a week or two.

I bet the boots will split in short order, keep a close eye on them. I had a set like that that didn't last 1,000 miles.

Why would a company that's been in business so long use CV boots that only last 1000 miles?

It's the number of folds, not the quality of the rubber. The ones I had with 2-3 folds broke from flexing.

Just keep an eagle eye on them for a while. YMMV.

I usually check things out when I change the oil and such but I'm honestly not really concerned with the cv boot difference. I'm convinced The Driveshaft Shop associates are experts in their field and trust them 100%.

They are probaby Level 2 units, which would be 400WHP at $840 per set...

Product Description:

The Level 2 axle set from The Driveshaft Shop. Over the past years Chevy has had a reputation of having very strong drivetrains. Let's start by looking at the factory center bar. Unfortunately the engineers seemed to have been pushed towards corporate bean counting instead of driveline excellence. This factory bar has a miniscule 23 spline that tapers down at the outer end that makes the center very weak. The outer CV is also made from a lower grade material and will just about handle the factory power. Our Level 2 axle has a larger 4340 chromoly center bar with a full 32 splines and the outer CV is not only made from a stronger material but has a 30% larger cage for even more strength. The ABS sensor is in the hub so no worries there. The inner CV has our standard spline plug design with a larger tripod (larger posts and more needles). All in all the axle will handle up to 400WHP and keep your car from the hooks of a tow truck on race day. So if you're ready to go hunting for a race, remember without axles it may be a faster race than you wanted.

They do sell Level 5 units that will handle 800WHP for $2,100...

I assume I don't have to point out the inanity of that question.

You are correct! They are level 2 units @ $419.99 each. Again, I greatly appreciate you selling me the GM axle to make this all happen.

Along the way, I learned that the different length axles (mentioned earlier) may "work" but the length difference may cause them to prematurely wear out. GM made the originals a particular length for a reason and it's nice to have a definite replacement available.
