So far the only upgrades I have done to my sierra right now are the Rollpan, bedcover, 2 inch rear shackle drop, tint, 20 inch boss 303's, the led strip brake light , a center console speaker box that i built myself with 2 inverted mtx 10's ...it still needs some vinyl..but im getting there..and also the 7 inch in dash monitor...but here in the next week im sending her in to the shop to get a billet grille installed along with the front bumper painted and the grille shell painted the same color as the truck...but the thing I really pumped up about is the 3" 4" drop thats coming up it should look pretty good tell me what you think.... GO SAINTS!!!!..... damn the bears
