The platform
The E-Box
A modular electric chassis built for big wheels from the first line on the page. Named for the box Chevy, engineered for everything that came after it.
Concept render — frame, suspension, drive unit, and battery pack as one platform.
What it is
The E-Box is a modular electric chassis platform born out of the E1. The name nods to the box Chevy — the cars that carried this culture — and the job is simple to say and hard to do: give big-wheel builds a foundation that was engineered for them instead of adapted to them.
For thirty years, riders have been solving real engineering problems with parts sourced from somewhere else. Lift a car and run 26s and the center of mass climbs with it. Stock brakes get asked to stop a rotating package they were never sized for. Suspension arms and spindles come out of the truck aisle because that's what's strong enough to exist. None of that is a knock on the builders — it's what happens when a culture outgrows the parts catalog. The E-Box is the catalog catching up.
A battery is heavy, and heavy is only a problem when you can't choose where it goes. On the E-Box, the pack sits low and centered, pulling the center of mass back down while the body keeps the stance riders build for. Brakes are specified against the actual wheel and tire package. Suspension geometry is designed for the ride height, not corrected toward it. And because it's modular, one platform can sit under a donk, a box, or a bubble.
Pack low and centered between the rails. Drive unit and power electronics aft. Suspension geometry built for ride height, not corrected toward it.
What it fits
First in line, then the rest of the yard.
First in line
Donk
'71–'76 Impala and Caprice. The ones that named the whole thing.
Box
'77–'90 Impala and Caprice. The namesake.
Bubble
'91–'96 Caprice and Impala SS.
Next up
Crown Victoria
Body-on-frame, big following, plenty of them.
Lincoln Town Car
Long, heavy, and made to sit right.
Oldsmobile Cutlass
A-body staple in the scene.
Monte Carlo
Two-door presence on big wheels.
Fitment order isn't locked yet — donk, box, and bubble come first; everything else follows as the platform proves out.
One platform. Any body on top.
Donk, box, or bubble — the E-Box sits underneath and disappears. Same stance riders build for. New current underneath it.

Eight subsystems, one system
The modules
Eight subsystems. Each one specified against the wheel package, not against a stock 1974 parts book.
- 01
Frame
The spine. Rails sized for pack integration and body mounting, with ride height for big wheels designed in rather than lifted in afterward.
- 02
Front suspension & steering
Purpose-built geometry for the ride height riders actually run — instead of truck spindles and arms adapted into the job.
- 03
Rear drive
Motor, reduction, and rear suspension packaged together, placed for balance and for the stance to sit correct.
- 04
Battery
Modular pack between the rails and under the floor. The heaviest thing in the car, put where it lowers the center of mass instead of raising it.
- 05
Brakes
Sized to rolling diameter, front and rear, with regen handling the routine slowing so the friction brakes stay fresh.
- 06
Power electronics & charging
Inverter, DC-DC, onboard charger, HV distribution, and a charge port that doesn't fight the body lines.
- 07
Body-mount interface
The defined handshake between chassis and body. Mount points, floor clearance, and firewall pass-throughs documented so a shop can plan a build before it starts.
- 08
Cooling, HVAC & 12V
Thermal loops for pack and drive, cabin heat and A/C with no engine to borrow from, and the low-voltage system that runs your lights, locks, and system.
Module specs are still in engineering, not marketing. We'd rather ship this page with no numbers than a number we can't stand behind.
