A 1976 CJ-5, Start to Finish
We're trying something new here — pulling back the curtain on an actual build in progress. First up: a customer's 1976 CJ-5.
This Jeep has been through a lot. A 4" body lift, steering that's more of a suggestion than a direction, a set of 35" tires pushing 12 years old, and two long-empty gun boxes eating up cabin space. It's a project that's earned its retirement from a gas engine.
The story behind it is a familiar one. The original owners' kid is finally old enough to want the Jeep — but not old enough, or interested enough, to keep wrenching on it every time it strands him. The parents aren't excited to keep footing repair bills either. An EV repower solves both problems at once: no more chasing down a tired inline-six, and with a home JuiceBox charger already installed and a daily driving need well under 60 miles, charging was never going to be the hard part.
Here's where the build stands so far.
With the ICE stripped out, the first real milestone is that MCA — it positions the traction motor exactly where it needs to sit, using the same frame mounting points the factory motor mount already used. Nothing cut, nothing welded.
Next up is the new front battery box — a "pizza box" layout holding four Tesla Model S modules, 2x2. It does double duty: powering the traction motor, and dropping the center of gravity while spreading that weight frame-rail to frame-rail over the front axle. Anyone who's felt a top-heavy CJ lean hard into a corner will appreciate that change.
Sitting above it is the Tech Box — home to the BMS, inverter, low- and high-voltage junction boxes, master disconnects, and the fuses for the new system. Everything stays below the grille rod line and stays accessible, so service (or future additions) doesn't mean tearing the Jeep apart. We're also planning to mount the on-board charger here — a combo unit that charges the main pack from AC power and doubles as a DC/DC converter for the 12V aux battery. Cooling lives just ahead of the motor, tucked below the battery box.
The platform leg mockup is where a lot of this actually comes together — the inverter and its Tech Box neighbors get their permanent home here. On the driver's side, we're routing the intermediate steering column through the same space; a little tight, but figured out. We've also nailed down the size and location of the rear battery box — more on that soon.
More to come as this one moves toward first startup.
