Well it still holds up in my daily driver I average 40-50 miles a day for a week so can't complain about that. Fel-pro has not yet disappointed. I've had a couple of their seals on my truck with no problems and this is a horrible 5.7 Vortec that seems to be extremely popular but suffers from all sorts of problems and is still holding up so keep up the good work and keep going you high-quality pads!
