Hot Rod Jim has sold the design of the TriFive Frames to Nerd Rods. Please check out their site for more information about their chassis offerings. www.NerdRods.com. The Nerd Rods version even comes in a Weld it Yourself Kit.

Hot Rod Jim’s Basic rolling chassis with Air Ride is designed to be a stable comfortable ride on a solid platform using inexpensive modern technology. The Basic rolling chassis with air ride uses the 1985-1988 Corvette suspension components, but replaces the stiff carbon fiber leaf springs with adjustable air bags. This chassis is ideal for touring cars, because it allows a low stance and modern suspension with no body modification required. The Air Ride offers you the softest ride you’ll ever find thanks to the ability to modify the spring rate on the fly. The Air Ride Shockwaves work best with the Air Ride Leveling System, not included with this chassis. This system automatically balances the car every time it starts to adapt the car to weight changes.

Options & Upgrades

Air Rail

The air rail is where we take your fame and seal 1 or 2 of the out side frame rails to make the air tank for your air ride system. This removes the tanks from your trunk and with the compressors mounted under the car on the frame rail. You will remove the vibration of the compressors and almost any noise that would normally vibrate into the cabin of the car by the system. One rail becomes a 3 gallon tank. We suggest more tank for bigger cars and a faster rise time.
