Part #: LSD 182 R. The Cusco Pro Adjust LSD is a top - notch, highly adjustable differential. Unlike the Type MZ and Type RS that need internal part swaps to change to 1.5 or 2 - way, the Pro Adjust LSD lets you precisely tweak sensitivity and locking speed in small steps using cam chips of different degrees. This allows on - track adjustments to fine - tune your race car's high - speed handling. We suggest these LSDs for pros only! Important Notes: Reach out to us if you have any differential - related questions. If you can't find your desired differential setup, contact us. Note that differential settings can only be changed during an overhaul after disassembly.
