A plated style Limited Slip Diff, but Titan use a coating technology on the plates called Sintrak. The main difference between this and other LSDs, is this finishing, as most other manufacturers just use a steel on steel arrangement or at best use a molybdenum finish (ZF use this coating). Titan's Sintrack (TM) finished plates give a far smoother operation whilst the plates are in use, so the driver has a better feel of the car & therefore the car is more driveable (which should result in improved lap times). Avialable in various lock-up rates: 30/60, 30/90, 45/45, 45/60 to suit what-ever use the car is being put to. Please note that this is for the LSD only and does not include for installation into a diff casing (which can be arranged - to either supply and install or install into your casing with new bearings etc. - We use and recommend Bara Motorsport for this service). DELIVERY is EXTRA.
