Sure Grip unit feels much better than Eaton TruTrac did..

I had a high speed vibration. I never narrowed it down to the pig. Then I smoked the tru trac in october. The 4th launch at Norwalk with a 318 probably making around 300 ft. Lbs. Street tires, coming out at 2500. They advertise 550 horse capability. But it came packaged in rice! Going back to my sure grip. So $1600 dollars divided by roughly 2000 miles, I'm sorry ma Mopar for going astray.
