I need a good rearend

[straitnate14]

well I guess I will finally show the murder. I went to the strip the other weekend and it didn't go well. I ran 3 times and I think I would be low 13's if I could just launch hard. Every time I launch at wot my locker unlocks and the drive shaft spins but the rear end doesn't. my dad only got two hole races on video the one I'm posting is a 14.30, my second run, 14.59 first run, and the third was a 16.somthing thats when I said the hell with it and tried to launch hard from 2500, It spun a little there was a bang and then grinding gear noise that I have come so ever fond of hearing.
