terrible parts and terrible customer service!!! do yourself a favor and read all the forums, they are crooks and will not warranty their faulty parts, I have a stock 2008 ram 25004×4 with a 68rfe trans, when the stock trans went bad at 145,000 miles I wanted to upgrade to a stronger transmission, I was told that Suncoast was the way to go, in 30,000 I have lost reverse gear and had a local trans shop tear it down, the failure was caused by the MEGA hub being broken, Ernie(this guy sounds like he wants to kill himself on the phone) said to send him the broken parts for him to check them out. I 2nd day aired the parts to him so that I can get my truck back on the road. it has now been 2 weeks and I have not received any parts or even a phone call from him. he will not return my calls, and no one know anything about my parts, they tell me they will leave a message for him. still no call or parts. I will never do business with this company again, they are liars and thief’s.
