Alfa Romeo 4C Drexler Differential

$0.00

Drexler plate type differential for the 4C gearbox. Plate type lsd unit gives progressive lockup and works even with one wheel off the ground. Due to higher service intervals, plate type differentials are recommended for racing only.

Drexler diffs come with preset ramp values for the 4C, set by the factory for the best drive characteristics. They are user serviceable and can be disassembled to swap to the different ramp settings as needed.

These are Drexler USA official differentials and include USA tech support from Drexler/A9. Contact us for info on custom ramp settings, pricing and lead times.

Drexler plate LSD units for the 4C are special order, contact us for a quote.
