FITS AM-20 PASSENGER CAR REARS ONLY. IT DOES NOT FIT JEEP REARS.
Eliminate your troublesome stock 2-piece axles with DoctorDiff ONE-PIECE, CUT-TO-FIT 29 spline axle shafts. Shafts are back oxide plated for corrosion resistance.
Axle package includes 2 1541 high-strength shafts with 1/2" x 2" or 1/2" x 3" lug studs (installed), 2 Green sealed ball wheel bearings (shipped loose), 2 lock rings and 2 inner seals (shipped loose).
Cut-to-fit shafts measure 30" (overall length) with 5" of spline which must be trimmed with a chop-saw to the desired length.
REMEMBER, THESE AXLES ARE MADE LONG TO FIT A VARIETY OF AM-20 PASSENGER CAR REARS. YOU MUST CUT THESE AXLES YOURSELF WITH A CHOP-SAW!
**I recommend removing the differential center thrust block, as this is not necessary and it can interfere with axle installation and wheel bearing longevity.
***If your vehicle is equipped with a power-lock (2-piece/bolt together) clutch style twin-grip posi, I recommend cutting the axles 0.1" longer than stock, for maximum spline engagement. Because of this, you MUST remove the differential thrust buttons. This involves removing the differential, so you can drive the roll pin out that retains the thrust buttons.
