I had them installed this morning and it was out and ready in only 2hours.It made a huge difference than the 3.42gears.I had Richmond 3.90's installed,I bought them off of my buddy and after he installed them it only cost me 220.00.I think I got a great deal.They only have 10,000miles on them also.I will be goin to the 1/8mile track next weekend in Navasota to see what it will run now that they are installed.I am hopin for 9.6's.What do yall think?I guess we will see next weekend and I will keep yall posted.I just thought I would let yall know
Later fellas
