Have not seen this yet. Looked on the S&S website but didn't find it. Got a part number to help the search a bit?

Exclusive S&S® Inner Primary Bearing Race!
Any Job Is Easy With The Right Tools!
High performance power trains take a serious beating.
That means that they require more frequent service.
Time is money, and in order to allow you to make
better use of your valuable time, S&S offers some new
tools for clutch and primary installation. First there
is a primary inner bearing race installation tool, with a
radial thrust bearing that decreases the effort required
to install a bearing race by 30%. Then there is the
new S&S Clutch Puller that is specifically designed to
remove an S&S high performance clutch. This is also
helpful when removing a stock clutch from a damaged
mainshaft. Finally there is an attachment for the S&S
Clutch Puller that allows easy removal of the primary
inner bearing race.
All of these S&S tools are CNC machined from the
finest 4140 tool steel and heat treated for maximum
reliability and service life.

The Race Is On... Or Off!
Saving You a Lot of Money and Trouble!
High performance applications often reveal problems with
stock power train components that were never anticipated
by the designers. One such problem is the tendency of the
stock inner primary bearing race on late model big twins to
shift on the transmission mainshaft under high torque loads.
This “walking” of the race can result in the destruction of the
transmission mainshaft seal and ultimately the output gear.
The result: costly repairs and annoying down time.
But not to worry! S&S has an elegantly simple, and totally
effective solution to this problem. A unique modification
to the design of the mainshaft inner primary bearing race,
positively prevents it from "walking" into the mainshaft seal
and output gear. The S&S bearing race features an extra step
on the inside diameter that acts as a stop on the transmission
mainshaft. When the race is pressed on to the shaft, the step
will not allow the race to move inward toward the mainshaft
seal. The improved S&S bearing race is a must for any high
performance application. It is included as a part of all S&S
high performance clutch kits, and can be retrofitted to stock
and aftermarket transmissions for all 1991-'05 big twins, and
2006 Harley-Davidson® Softail® models.

Hoist!
