Everything Your Classic Needs

Whether you are ready for a complete EV conversion or just exploring the idea, we have a service that fits. Every engagement follows the same rigorous standards and attention to detail that define our process.

Full EV Conversions

Our flagship service. We remove the entire combustion drivetrain and replace it with a purpose-engineered electric powertrain, tailored to your vehicle's chassis, weight, and character. This is a ground-up transformation that turns your classic into a refined, reliable, daily-capable electric vehicle. Learn more about what a full EV conversion involves, review our six-step build process, or check our pricing guide for transparent cost breakdowns across three tiers.

Complete drivetrain removal and electric motor installation
Custom lithium battery pack design and integration
Battery management system with thermal regulation
Regenerative braking calibration
Onboard charger and DC fast charge prep
Electric power steering and vacuum brake assist
Full wiring harness with CAN bus integration
Original gauge conversion with EV senders
Comprehensive testing and commissioning protocol

Partial Conversions & Hybrid

Not ready to go fully electric? A partial conversion or hybrid setup lets you add electric assist while retaining your original engine. This approach works well for owners who want improved drivability and reduced emissions without a full commitment. We use the same motor and battery technology as our full conversions, scaled to work alongside a combustion engine rather than replacing it.

Electric motor assist paired with existing engine
Supplemental battery pack for electric-only city driving
Integrated power management between both drivetrains
Electric A/C, power steering, and accessory upgrades
Staged conversion path — go full EV later if you choose
Full reversibility with documented original components

EV Repairs & Upgrades

Already have an EV-converted classic — whether we built it or someone else did? We service and improve existing conversions. From battery pack health assessments to motor upgrades, charging system improvements to wiring harness corrections, we bring the same precision to repair work as we do to new builds. If your current conversion is not performing the way it should, we can diagnose and fix the issue.

Battery pack health assessment and cell balancing
Motor and controller diagnostics and replacement
Charging system upgrades (Level 2 and DC fast charge)
Wiring harness repair and CAN bus troubleshooting
Thermal management system improvements
Battery capacity upgrades for extended range
Software updates and performance tuning

Our Difference

What Sets Us Apart

There are shops that install electric motors, and there are shops that build electric cars. We are the latter. Every conversion that leaves Silent Classics has been engineered as a complete system — not a collection of aftermarket parts bolted together.

Automotive and electrical engineering under one roof. Our team understands both the classic car and the modern EV systems. That dual expertise shows in every build.
Transparent, documented process. From intake to delivery, you know where your build stands at every stage. Read about our full build process.
Reversible by design. We catalog and preserve every original component. Your car's history is protected, no matter what the future holds.
Results you can see. Our completed builds gallery speaks for itself. Real cars, real owners, real results.

Investment

Transparent Pricing

We publish our pricing tiers openly because we believe you should know what a conversion costs before you ever pick up the phone. Our three tiers — Essentials, Performance, and Concours — range from $25,000 to $80,000+, depending on the power, range, and level of customization you choose.

Wondering whether a conversion makes financial sense in the long run? Our gas vs electric comparison breaks down the total cost of ownership, and our why convert page makes the broader case for the investment. Still have questions? Our FAQ addresses the most common cost and logistics concerns.

By Vehicle

Explore by Vehicle

While we work with nearly any classic car, these platforms have dedicated pages with model-specific specs, conversion details, and estimated costs to help you plan your build.

Ford Mustang

The first-gen Mustang's lightweight platform and simple rear-drive layout make it one of the most rewarding and cost-effective classics to electrify. The electric version accelerates harder, handles better, and starts every time.

Mustang conversions

Land Rover Defender

The Defender gains massive low-end torque and loses its thirstiest, leakiest component. The result is a quieter, more capable vehicle that is even better off-road and infinitely more pleasant on-road.

Land Rover conversions

Classic Pickup Trucks

Vintage trucks offer generous space for battery placement and robust frames that welcome the added weight. The combination of classic truck styling with silent, instant electric torque is genuinely addictive.
