Once you get past the custom bodywork and updated faade, you'll see that the interior is just as worthy of praise. The factory seats were cut down by Steve Chapman and were sent to Renn Upholstery in Clovis, California, to be covered in gray, blue, and white Enduratex, while the headliner is all gray suede. The rest of the interior is equally custom, as Ryan and Tom Alvitrez fabricated custom door panels, the entire dash, and the center console, which is one piece. The fiberglass doesn't stop at the dash, as the entire cargo area is now the home for a barrage of Earthquake audio. Six 12-inch Sub Zero subs are powered by PH5000 and PH10000 Eathquake amps, and receive audio from an Alpine IVA-W205.

Since the Blazer is a cruiser and not a racer, the performance modifications went into the parts that would do the most good. SSBC brakes were bolted onto each corner, and the 4.3L V-6 received JBA headers and Flowmaster exhaust. Of course, the audio system needed a boost, so a Kinetik power cell replaced the OEM battery.

After four years of work, with an especially hectic two months preparing for SEMA, Ryan's Blazer is finally finished. Judging by the results, we say it was worth the wait, and we wouldn't be surprised to see more '07 Sierra conversions in the future.
