Don’t let a neglected undercarriage ruin your detail. Classy Chassis is an undercarriage spray that gives you "like new" looking wheels wells and frame. Simply mist it on your inner-fender guards, frame supports, and suspension components to give your ride that classy look it deserves.
Unlike water-based dressing that break down with your next wash, Classy Chassis is solvent based meaning it resists water making it last longer!
Check out our Undercarriage Kit
Spray Classy Chassis onto the surface and allow to soak while you perform other parts of the detail. Come back with a paint brush (that's what we like to use) and brush over the surface. This evens out the finish and eliminates any "veins" left in the dressing.

I am blown away with how well this stuff works. A little goes a long way when you follow the proper decontamination prep. Made my faded wheel wells and stock suspension absolutely “POP”! I’m buying more as soon as possible.

The best products on the market, no sling just clean thoroughly, wait to dry, apply Classy chassis on inner plastic fender let it cure for few minutes wipe to dry & decked out as well will put another review for that one

Classy Chaassis does miracles. Brings back that new car look. Best part of it is that it doesn’t leave a greasy film that will attract dirt.

Love this stuff! Tried other brands, MANY other brands and this is just the best. Easy, levels out and keeps my frame looking good. My 2018 Duramax frame is wax and this soaks in and keeps it nice!
