Thanks for providing the list of parts.
I'm in the process of rebuilding my
axles, so I've found it very helpful.
I don't have Summers Bros axles but some
of the parts I have are similar to your
list.
U-joints - See if you can use
the Spicer 5-1310X (no zerc) or 5-810X (zerc on
bearing cap)
http://www.northerndrivetrain.com/product/SPI-5-1310X.html
These both have a
much beefier center section.
I'd prefer to use a u-joint without the zerc
fitting in the center section.
But if you must make sure it is under
compression during acceleration.
Cheers,
Tim

RE: Summers Bros Axles
A list member, Russ Moore has a Spitfire axle design
that uses Summer Bros
Axles (I don't know if these are the same axles Mark
has) and Corvair U
joint flanges.
Here's a list of the PNs from the Bill of
Materials he sent me. I've had a
set on my spitfire race car for a few years
now with out any problems.
Prior to that I had a set of Steve Johnson designed
axles that were
stronger that the stock ones, but used the stock spit U
joints. I would
break / wear out a joint at least once a season. One time it
put me into
the wall at Limerock.
Russ has a shop, besides being a Spit
racer, and can give you more details
if you like.
U-Joint NEAPCO 1-0153HD or
Spicer 5-153 $12.08 -4
Outer roller bearing J-2012 Torrington $ 13.32 -4
