After my recent install of my sleeper06 ported juggs after breakin finally got to let it loose. And it is amazing how much more top end I have but my clutch HATED IT. It would just let go and the engine would free spin in very high rpm. But we are talking about a tusk heavy duty not bad for 35$. Quick call to driveline had me on the road in no time even sent me another set of springs for free. Easy to communicate with knowledgeable and friendly plus the price wasn't bad. My 4mm puts it to the ground now. Next have to upgrade the mounts the motor is twisting during a hard launch but the clutch takes every bit of. Hope someone finds this helpful would definitely recommend driveline dune clutch.
