Product details
EMPI's 87-5871-0 is the torque distribution washer for 108mm O.D. Porsche 930-type C.V. joints, fitted under the C.V. bolt heads so bolt clamping force is spread over the joint face. EMPI groups these washers with the 12-point C.V. bolts as axle mounting hardware, and each one is sold individually. Bent or missing washers are common on used axles, and a rebuild is the time to replace them.
EMPI makes the washer in three sizes to match the three common joint diameters. The 87-5080 fits 90mm Type 1 joints (ref. 113 501 329), the 87-5081 fits 100mm Type 2 joints (ref. 211 501 357), and this 87-5871 fits 108mm 930 joints. The 930 joint uses 3/8 inch-24 bolts through six 10.4mm holes, so the smaller washers will not line up. When rebuilding 930 axles, the usual order adds EMPI's 16-2413 bolts (3/8 inch-24 x 2 1/4 inch, 12-point, set of 6), an 87-5870-0 end cap, and a boot.

Fitment & Compatibility
Sized for 108mm 930 joints, including EMPI's 87-9469-B, 87-9470-B, and 98-5094-B and the Lobro 98-5093-B (Porsche 930 332 034 00). The same joint size turns up on VW builds converted to 930 joints with EMPI flanges and stub axles. Type 1 and Type 2 joints need the 87-5080 or 87-5081.
Common Questions
How many washers do I need?
They are sold one at a time. Count the washers on each joint you are rebuilding and order that number, plus a spare for any that are bent.
Will this fit my Type 1 C.V. joint?
No. The 90mm Type 1 joint takes the 87-5080 washer. This one is for the 108mm 930 joint only.
