4K? That's not bad. Buy one, sell the transfer case for $750-1K, the transmission for $1.5K and you now have yourself a complete drop-in GEP for $1,500-1,750. Not bad at all.
Yeah so update on my deal, it turned out to be the SS diesel injectors! POS they are. Put some Bosch injectors on it didn't even balance them runs great.
Glad you got it fixed. Glad the ss ripoffs didn't put any holes in the pistons. One more person to spread the word about ss junk. Hopefully one day that outfit will go out of business.
