IRS Donor Parts

 

 

*_ Vehicles:_*

            In all applications make sure that the diameter of the axle 
shafts at the splined ends measure 1.2 inches, the differential has 8.8 
cast into its top, and that rear disc brakes are present on the donor 
IRS.  To determine the gear ratio, and whether or not the unit has 
posi-traction, look at the tag that is attached to one of the 
differential cover bolts. The first 4 spaces signify the gear ratio and 
whether or not it has posi-traction.  If the unit has posi-traction, 
then the second space will have an L in it representing (limited slip), 
the remaining spaces specify the gear ratio.  For example, 2 L 7 3 means 
posi-traction with a 2.73:1 gear ratio.  Most people pay a salvage yard 
between $300-$400 for the donor parts.  Also, Ford Motorsports sells a 
15lb. lighter aluminum carrier with gears and posi-traction for around $650.
