The FDF Axle spacers are designed to prevent axle failure on lower or higher horsepower cars. The idea is to maintain the factory axle length, and have full CV engagement.
These adaptors are precisely machined to centre perfectly on the diff and axles, safely extending them.
Included in the kit is:
12 - Grade 10.9 bolts
2 - Spacers
Good quality
They work as designed and fit perfectly. The spacers just work! I would buy again, however if I need to then something bad happened.
