Overview

The AMS Performance Q50 and Q60 Rear Limited Slip Differential (part number ALP.28.03.0003-1) replaces the open factory differential, which lets one rear wheel spin and lose traction under power. AMS designed a helical LSD that mechanically limits slip so both rear wheels work together.

The result is better traction in a straight line and through corners, whatever the road conditions. The gears are made from HRC60 hardened 8620 forged steel for long-lasting reliability.

Because it is a helical design, it is quiet, with no chatter, clunking or binding at low speed, and it needs no extra maintenance compared with the factory unit. AMS recommends Motul Gear 300LS 75W-90 oil.
