What is a Dodge build sheet?

A build sheet is the factory's own record of how one specific vehicle was assembled. For a Dodge it lists every sales code — engine, transmission, axle, paint, packages, and options — tied to the VIN.

It's the most reliable way to confirm how a used Charger, Challenger, or Durango was originally configured — far more dependable than a badge or a listing.

What the build sheet shows

Powertrain, trim, exterior and interior colors, wheels, option packages, and dealer-installed-at-factory equipment — the details that explain why two cars with the same model name can feel completely different.

On performance models it separates the genuine hardware — Scat Pack, SRT, Hellcat equipment — from appearance packages that only look the part.

Sales codes explained

Stellantis / FCA vehicles use 3-character factory sales codes on the build sheet. One package code can bundle several smaller features, so reading the sheet carefully tells you what the car actually carries.

Factory data is the baseline, not proof of current condition — wheels, audio, and trim may have changed since delivery, so use the sheet alongside photos and an inspection.

Dodge Axle Ratio by VIN and Build Sheet

The axle ratio is the most consequential spec you cannot see. It shapes how a Dodge accelerates, what it can tow, and what it costs at the pump, yet nothing on the outside of the car reveals it.

The ratio describes how many times the driveshaft turns for each turn of the wheels. A numerically higher gear delivers stronger launches and better pulling power; a numerically lower one relaxes the engine at highway speed and helps fuel economy.

Dodge used this lever constantly. The same model could ship with different final drives depending on engine, trim, performance package, and towing equipment.

Performance cars are the clearest case. Scat Pack and SRT models paired their V8s with aggressive final-drive choices, and drag-oriented buyers care about exactly which one their car received.

The differential type matters just as much as the ratio. Dodge offered an anti-spin limited-slip differential as factory equipment on many models, and it appears as its own line in the build record.

None of this is stamped where you can casually read it. The dependable source is the factory build sheet, where the axle and differential are recorded as sales codes for your exact VIN.

Enter the 17-character VIN in the lookup on our home page and the site retrieves that factory build sheet and equipment listing.

Buyers towing anything should check this line first. The ratio was part of how the factory set tow ratings, and two otherwise identical trucks or SUVs can be rated very differently; see Dodge Towing Package by VIN: Verify Factory Equipment for the full picture.

Drag racers read the same line for the opposite reason, calculating launch behavior and cruising rpm before ever buying the car.

Service depends on it too. Limited-slip units want specific gear oil and friction modifier, and rebuilding or regearing starts with knowing what is in the housing now.

If a previous owner regeared the car, the build sheet exposes it. A recorded ratio that does not match observed rpm at speed means the differential has been changed.

That is not necessarily bad news, but it is information you want before purchase, because regeared cars were usually driven hard.

The axle works as a system with the gearbox, so read both lines together; our Dodge Transmission Code by VIN and Sales Codes guide covers the other half.

One lookup answers a question you physically cannot answer in a parking lot. That is the build sheet doing exactly what it was written to do.
