I finally had a chance to try the new 10.4 sheeves and a clutch kit from Dakota Performance and I know all clutch kits are going to vary but I am curious what to expect. First off, the primary spring is orange and the secondary spring is silver. It engages at 4300 rpms and it seems to peek around 8100 rpms. Right now, the conditions are not very good and nothing to compare it against so I am not sure what to expect. Let me know what you think.
