Are Chevy Silverado and GMC Sierra parts interchangeable?

Engines and transmissions: Identical between Silverado and Sierra on the same platform. A 5.3L from a 2012 Sierra drops straight into a 2012 Silverado.
Suspension: Control arms, shocks, springs, sway bars, spindles — all the same.
Brakes: Calipers, rotors, pads, brake lines — identical.
Drivetrain: Transfer cases, differentials, driveshafts, axle assemblies.
Electrical: Alternators, starters, wiper motors, power window regulators, door lock actuators.
Bed components: Beds were the same between brands through 2018. After 2019, Silverado and Sierra beds diverge — verify before pulling.

Yes, within the same generation. Engines, transmissions, suspension, brakes, and drivetrain are identical between brands. Body panels (grilles, headlights, hoods) are brand-specific. Interior parts vary more by trim level than brand.

What are the best Silverado parts to grab at a junkyard?

LS engines ($500-$2,000), 4L60E transmissions ($300-$800), transfer cases ($200-$500), tailgates ($150-$400), and tow mirrors ($50-$150). GM truck parts hold strong value due to the massive installed base.

Do 1500 and 2500 Silverado parts interchange?

Mostly no. Despite sharing generation names, 1500 (half-ton) and 2500/3500 (HD) have different frames, suspension, brakes, and axles. Some engines cross with appropriate mounts, but transmissions differ (Allison in HD vs. 4L60E/8L90 in 1500).
