Excellent product and service ordered a rally clutch tuesday and it came the next day. Got the truck back today and the clutch is very smooth it doesn't chatter like the stock clutch did. My stock clutch was in good shape about 60% gone with 140,000 miles on it. The pilot bushing seized up on the input shaft so I had a new input shaft kit from South Bend Clutch put in as well. I figured since it was apart better to put in a new clutch.
