Cole Brannan

Cole Brannan is the editorial byline behind silverado.parts. The beat is narrow on purpose: one truck, every generation of it — GMT800, GMT900, K2XX, and T1XX — and the parts that actually bolt to each one.

Most of what gets published here is reference work rather than opinion: bulb sizes by position and generation, OEM part numbers for the console lids people keep breaking, oil capacities and service intervals by engine, the brake-pad compound and edge-code language that shows up on a box but never gets explained. That kind of logistics is what a Silverado owner is usually searching for at 9pm with the truck already apart, and it is the part of the internet that has gone stale or vanished behind forum logins.

Sourcing rule: fitment claims come from factory service data, RPO code documentation, and part-number cross-references — not from guesses. Where a spec genuinely varies by trim or build date rather than by model year, guides say so plainly instead of publishing a chart that is wrong for half the trucks reading it. Corrections are welcome and get made.

Part picks are based on real availability, actual buyer reviews, and fitment — never on payment. No brand pays for placement here. Prices are never invented or cached: new and aftermarket parts link to Amazon where the live price lives, and used, OEM, and hard-to-find parts go to live eBay Motors listings where the seller sets the price. When a listing dies or goes out of stock, the site catches it in a daily check and flags or swaps it rather than quietly leaving a dead link up.

Where to start

The reference spine of the site is the Silverado generations & fitment guide (which generation your truck is, and what that changes), the maintenance schedule & parts checklist, and the common problems by generation breakdown. From there, everything branches by system — brakes, lighting, suspension, interior, and the rest of the parts categories.
