With the EGR kit I used replacement parts are readily available. Cost was $1,075 w/slotted rear rotors. The other source posted sounds $250-$300 bucks cheaper. You might try them but I went w/EGR as they've been in business for awhile. We still ran into some difficulties even w/EGR. I went w/Sam Patterson's pads and high-performance front rotors plus oversize rear wheel cylinders with marginal results. Finally,I can stop this truck pretty safely. Short of selling mine and borrowing $20,000 it was the only choice at this time. I've got my eye on an 07 as it sounds pretty good.
