Among GMC's legendary C25 trucks, this 1975 Sierra Grande pulls rank as a 3/4-ton bruiser with big-block motivation. The Dark Orange and White two-tone paint amplifies its rugged squared-off profile, while the calculated 3-inch front and 4-inch rear drop transforms its stance. Eight-lug powder-coated 16-inch steel wheels roll on LT245/75R16 rubber, giving this pickup its planted appearance. The tough-as-nails bed features industrial-grade Rhino-lining and diamond plate rails, while the mirror-finish chrome bumpers and full-length trim provide crisp contrast against the paint.
Opening the doors reveals a fresh take on the classic GMC cabin, where beige and dark orange create a bold atmosphere. The vinyl bench provides proper seating for three, while custom-crafted wood grain accents flow across the dash and door panels. A modern Bluetooth stereo system pumps sound through strategically placed 6x9 speakers in the cab corners. The leather-wrapped steering wheel and column-mounted shifter put total control at hand, backed by power steering for effortless maneuverability.
Motivating this Sierra Grande, a mighty 454 cubic inch V8 links to a TH350 3-speed automatic transmission. The combination exhales through Hedman long-tube headers and a custom-engineered 3-inch exhaust system capped by a Black Widow Venom 250 muffler - producing a deep, authoritative tone. Power disc brakes bring everything to a halt. The modified suspension utilizes drop spindles and revised leaf spring hangers, while the stout 14-bolt rear axle with 4.11 gears puts the power down.
