What Is a Valance on a Truck?
If you have been told your truck needs a new valance, or you have seen the word on a parts diagram and had no idea what it meant, here is the plain answer.
What a valance actually is
The valance is the low panel that sits under your front bumper, between the bumper and the road. On most trucks it is a molded plastic piece that spans the width of the front end and hangs down a few inches.
You will also see it called an air dam, a lower valance, a front spoiler or a chin spoiler. Different manufacturers and parts catalogs use different words for the same panel.
Valance or valence? Both spellings turn up
The correct automotive spelling is valance. Valence is a chemistry term, but it gets typed constantly when people search for this part, so if you have been spelling it that way you are in very good company and you are looking for the right thing.
The word itself comes from drapery, where a valance is the short piece of fabric that hides the top of a curtain rail. Same idea on a truck: a panel that closes off the gap underneath.
What it is actually for
The valance is mostly an aerodynamic part. At road speed, air that goes under a vehicle creates more drag than air that goes around it. The valance blocks some of that flow and pushes it around the sides instead, which reduces drag and helps fuel economy slightly.
It does a second job as well, which is shielding. Anything mounted low at the front of the truck gets a little cover from road spray, gravel and salt.
What it is not is structural. Losing your valance will not affect how the truck drives, steers or stops.
Front valance and rear valance
Most people mean the front one. There is usually a rear valance too, the panel below the rear bumper, and on some trucks it is where the exhaust exits through a cutout. Same word, opposite end of the vehicle.
What happens if yours is cracked or missing
It is the single most commonly damaged panel on a truck, and the reason is geometry. It is the lowest point at the front, so it is what finds parking blocks, steep driveway aprons, snow banks and trail obstacles first.
A missing valance is not dangerous and it will not fail an inspection in most places. You will likely see a very small drop in highway fuel economy and a bit more spray reaching things behind it. Plenty of people who take their trucks off road remove the valance deliberately, because it is the part that limits approach angle and it is the part that gets torn off anyway.
So replace it if you care how the front end looks, or if you want the aero back. Do not lose sleep over it otherwise.
Why people put lights on it
Because of where it sits, the valance is the best position on a truck for throwing light forward and down onto the road ahead.
That is a different effect from the other two common lighting positions. Rock lights light the ground underneath the truck. Wheel lights light the wheels. Valance lights push a line of light out in front, which makes the front end read wider and lower and gives you a lit approach when you pull in somewhere at night.
It is also the easiest of the three to install by a wide margin, which is why people who are building up gradually tend to start here.
What a valance light kit involves
Our plug and play valance kit is genuinely plug and play. There is no splicing into factory wiring and no cutting between the lights. It does still need a power source, which can be a switched and fused circuit, an upfitter switch, or one of our harnesses. The strips mount with adhesive.
Most people finish in under an hour in a driveway with basic hand tools. If you have ever been quoted shop labor for lighting work, this is the job you do yourself and keep the money. The valance installation guide walks it through with photographs.
Picking a size
We ship three, and the only question is how much of the valance you want lit.
- 10 piece covers the valance on most standard front ends.
- 15 piece is the most popular size and the right call for most trucks running an aftermarket bumper.
- 20 piece is full coverage for wide front ends and heavy duty trucks.
All three use the same hardware, so you are not choosing between different products, only how much coverage you want.
Measure before you order
Run a tape along the valance from one end to the other. If your front end is stock and you are under roughly 60 inches of usable run, the 10 piece will cover it. Aftermarket bumpers and heavy duty front ends usually want 15 or 20.
When you are between two sizes, size up. Extra pieces give you flexibility in spacing, and tight spacing looks better than gaps.
Durability, and the step people skip
The valance is the most exposed lighting position on a truck. It takes road spray, gravel, salt and everything the tires ahead of you throw at it. Our kits are built for that and carry our limited lifetime warranty.
One install step matters more here than anywhere else on the vehicle: clean the mounting surface properly. Wax and road film are why adhesive lets go months later, and it is the most common reason a strip comes loose. Two minutes with a proper prep wipe is the difference.
Still not sure what you are looking at
Send us a photo of your front end and we will tell you what panel you are pointing at and whether a kit will suit it. You do not have to be buying anything.
If you already know what you need, the kits are on the valance lights page.
