SPAL SHAVED-40 Door Popper Kit | Dual 40lb Solenoids + 7-Channel Keyless Entry System

Clean Doors. Smarter Access. Proven Reliability.

When building a clean, modern custom vehicle, nothing completes the look like shaved door handles — and nothing makes them functional like the SPAL SHAVED-40 Door Popper Kit. Engineered and manufactured by SPAL Automotive, this complete kit delivers reliable, high-torque actuation and secure remote access through an integrated 7-channel control system.

Each kit includes dual 40-pound pull solenoids, two wireless transmitters, a seven-channel receiver module, all necessary wiring, connectors, and hardware. Designed for universal 12V systems, the SHAVED-40 is the ultimate all-in-one solution for clean door conversions, trunk releases, or compartment access in custom builds, hot rods, race vehicles, or show cars.

With over 40 pounds of pull per solenoid, this kit can open even heavy steel doors or latches with ease. Every system is pre-configured from the factory for plug-and-play reliability — no complex programming, no guesswork, just SPAL’s signature OEM-grade precision.

Designed for Builders Who Expect More

The SHAVED-40 system brings together everything needed for a reliable remote access setup: powerful solenoids, weather-resistant electronics, and versatile control logic. The receiver module can operate up to seven different outputs, including door solenoids, trunk releases, fuel doors, or auxiliary circuits.

SPAL’s integrated safety design includes a built-in lock pulse timer and system protection timeout, preventing over-activation and protecting your solenoids and wiring from damage. The receiver is also pre-programmed to support up to four key fobs (two included), each capable of activating multiple channels simultaneously — offering complete flexibility for complex custom wiring setups.

Technical Specifications

Functionality and Integration

The SPAL SHAVED-40 is capable of controlling up to seven separate electrical functions via negative or positive output triggers. Channels 1 and 2 operate on-board relays (for solenoids), while channels 3–7 can be tied to auxiliary relays for custom devices like trunk releases, fuel door actuators, or power windows.

Each transmitter button can be configured to activate specific channels individually or in combination — giving builders complete control over access points, lighting, or power accessories.

The system includes:

• (2) SPAL 40lb solenoids

• (2) key fob transmitters

• (1) seven-channel control receiver

• (1) high-current switch

• Complete wiring, fuses, connectors, and mounting hardware

Installation Notes

The SHAVED-40 kit is a universal 12V system that can be installed in virtually any vehicle. The receiver should be mounted inside the cabin to protect it from moisture, while solenoids can be mounted near latch mechanisms using the included brackets and cables.

Standard setup: Pulls directly on latch mechanism arm.
Reverse pull setup: Uses cable looped around pulley for inverted latch orientation.

⚙️ Wiring Guidelines:

• Connect white wire to driver door solenoid; yellow wire to passenger door solenoid.

• Black solenoid wire to ground on vehicle body.

• Receiver red wire to +12V fused power; black wire to chassis ground.

• Mount an emergency backup switch outside the cabin for manual override.

SPAL includes all necessary hardware for mounting, but backup mechanical release is strongly recommended for safety.
