Chevrolet tools & data

By CarWhere Research · Updated

CarWhere’s Chevrolet hub collects free research for Chevy shoppers and owners: 19 GM engine and transmission guides from the LS3 and LT1 to the 5.3 V8 and Duramax, 107 trim levels with dated base MSRPs, 55 known issues and recalls by model, plus a VIN decoder, RPO codes and pricing data. Every page lists its sources.

One Silverado model year can combine four engines, three cabs, three beds, several axle ratios and a dozen packages such as Z71 and Max Trailering, so the trim badge rarely tells the whole story. These pages explain what each engine, trim and generation offered and what to check on a specific vehicle before you buy it.

Frequently asked questions

How do I find out what options my Chevrolet has?

GM records each vehicle’s factory-ordered options as three-character RPO codes against the VIN, and prints them on the glovebox Service Parts Identification label when it is present. The original window sticker or a build sheet decoded from the VIN lists the trim, engine and packages; the free VIN decoder shows basics such as engine, body and plant.

What is an RPO code?

RPO stands for Regular Production Option. GM uses three-character codes such as Z71 (off-road package), L84 (5.3L V8) or NHT (Max Trailering) to identify the options and equipment a vehicle was ordered with.

Which trucks and SUVs are in the 6.2L V8 recall?

NHTSA campaign 25V274 (2025-04) covers 2021–2024 Cadillac Escalade/ESV, Chevrolet Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon/Yukon XL with the 6.2L V8 (L87). Run the VIN through NHTSA’s recall lookup to see whether a specific vehicle is included.

What is the difference between the LS and LT engines?

LS is GM’s Gen III and Gen IV small-block V8 family (1997–2017 in various models), and LT is the Gen V family introduced for the 2014 Corvette and trucks, with direct injection and variable valve timing. The GM engines guide covers each version by year.

How do I check a Chevrolet for recalls?

Enter the 17-character VIN on NHTSA’s recall lookup or Chevrolet’s owner site, or ask a dealer to run it. Recall repairs are free. CarWhere’s known-issues pages list major recall campaign numbers by model and generation.
