Ultimate Hot Rod Glossary – The U’s and V’s
Undercarriage: Usually used to refer to a vehicle’s steering and suspension, but may also include all other components found under the body.
Understeer: Understeer is the sensation where the rear end of the car experiences more body roll while corning than does the front. The result is that the front end has a tendency to slide or “push” before the rear. Understeer can be reduced – or even eliminated – by adding or increasing the size of the rear anti-sway bar.
Unibody: A vehicle chassis design where there is no separate frame. Instead, the structural integrity of the chassis is built into the body. Unibody vehicles often utilize “subframes” for the mounting of suspension components.
Used: Used parts are just that…”used”. Such parts are typically sold “as-is” with no warranty or any effort to repair or refurbish them. Often, used parts will require extensive labor to refurbish to a point where they will be acceptable to use on your project. The cost to refurbish some parts (particularly trim items) can easily exceed the cost of reproductions by double or triple.
VIN: This is an abbreviation for the Vehicle Identification Number, the car’s identification that carries its serial number, model, year of manufacture and basic equipment information. It’s usually stamped onto the vehicle, either under the windshield post, the driver’s door post, or on the firewall.
Vintage: A vehicle built between 1915 and 1942 in stock or unmodified condition.
