    Installation Notes. Installing the mini spool is requires knowledge of your differential, spider gears and halfshafts. The installation must be done correctly otherwise the result could be extensive damage rather than better traction.

        Would I need to use the stock clutch's in the diff or take them out.

        • Generally when replacing any parts of your rear diff, you would want to replace and rebuilt the entire application as it's usually more complicated to reuse pieces than to just start from scratch, plus if one piece needs replacing it usually means the rest will need replacing soon anyway.

            To much noise when slowing down

            Install this mini spool with some 4.10 gears nice when driving they do there job it’s definitely as close to a full spool to locker differential but I wouldn’t do it again to much noise from the blocks in the center of the mini spool they get the job done but make a lot of noise when slowing down when cruising fine
