10 bolt with LPW Girdle & Axle Tube Brace
#62
I believe they are also spot welded from GM, not just pressed on. It is an ok design until, under traction, they twist. Fully welding them all the way around the tube helps this a bit.

Im about to order parts for this project and before I do I wanted to know If a solid pinion spacer is worth installing. Im not even really sure how it benefits the rear end. Can someone enlighten me?
#65
I wouldn't know if it is worth it or not. I'm not sure at what horsepower level the crush collar becomes a liability with the 8.8. I do know the crush collar takes a butt load of torque to actually crush--it's not like you can just crush it with a ratchet. Maybe someone else can chime in here.

Solid pinion spacer is a good idea if you don't mind the extra work in setting it up. Typically, these style rears use a crush collar that literally crushes down to help set clearances with the pinion depth in the housing. The downside is that, under high horsepower applications, the crush collar can be further crushed, changing the pinion depth and contact patch of the gears, ultimately weakening the strength of the rear. The solid pinion spacer eliminates this problem, but requires more work getting the other shims to compensate for the now fixed depth due to not having a crush collar.

They can be a PITA to install, even for someone with lots of experience.

Exactly. Housing flex caused from wheelhop or driveline shock can compress the crush sleeve causing inadequate pinion bearing preload which can allow the pinion to move around in the housing affecting gear mesh. An early indicator of this is the common pinion seal leak.

Any general ballpark horsepower figures/types of usage about when to consider putting in a solid pinion spacer, both for an 8.8 and the 10 bolt?

This is one of the best threads in a long time on read end set-ups.
Question - does anyone have a link to a video or perhaps a pullaway diagram of these rearends? I would love to watch a short video of one being torn down - or more specifically, the alignment set-up of the internals.

From what I understand its a combination of a solid pinion spacer and crush sleeve. The manufacturer says its easier to install and has a superior cycle duty compared to the traditional solid pinion spacer.

Where is everyone ordering their LPW girdles from? I looked through some site sponsors and wasn't able to find anyone that stocks their products. If somebody could PM me something if their source is not a site sponsor i'd appreciate it. Thanks!

The company's name is LPW Racing - Google it. None of the sponsors carry their products, so buy from them direct.

Here is my finished project. I can't wait until I can install it.
Check out the pics.
Here are the parts:

Installed with pics, didn't cost much so we will see how time will tell..
Blew my carrier up a few weeks ago, got a used one on here cheap + LPW Ultimate Girdle & Axle tube brace kit for the 10 bolt. Had to have the the drivers side brace cut since it didn't fit and requires some welding for brackets. Pics below.

LPW said it should take less than two hours to weld the tabs and measure the bar length and then weld the rod ends to each bar.
Looks to me like eight welds.

I have a TA girdle on my 10 bolt and a Moser girdle on my Moser 12 bolt.
IMO there isn't enough material forged into a TA girdle that will support the forces of the axle braces.
The LPW girdle forged their girdle with extra material on each side to tap bolt holes in order to attach the brace rod ends to both axle sides.
