The package includes all necessary bushings, fasteners, and complete installation instructions.
Moroso Push/Pull Kit — Battery Disconnect Kit
The Moroso Push/Pull Kit provides a complete battery disconnect kit with all required components in a ready-to-install package. The item’s dimensions and weight are listed for planning purposes, and it is suitable for race and performance vehicles requiring a reliable, easily accessible disconnect solution.
Moroso 74111 Battery and Alternator Disconnect Kit
The Moroso 74111 kit features a push/pull remote switch designed for roll cage mounting. It includes a four-pole master disconnect that can cut power to both the battery and alternator feeds simultaneously without relays. The kit comes with an 18″ aluminum actuator link, brackets, swing arm linkage, decals, and all fasteners, designed for a clean exterior car installation.
Buying Guide: How to Choose a Push/Pull Battery Disconnect
Key considerations include current rating, voltage range, mounting options, and installation environment. For street vehicles, a 125A or 300A unit typically suffices, while race cars may require higher ratings and dual-pole or four-pole configurations to disconnect both battery and alternator circuits.
- Current rating: Match the unit to your system’s peak load and safety needs. A higher rating provides a robust margin for startup surges and accessory loads.
- Voltage compatibility: Ensure the device supports your system’s voltage (commonly 12V, but some units handle up to 36V DC).
- Activation force and accessibility: A smooth, easily reachable push/pull action improves safety during emergencies and routine use.
- Mounting and compatibility: Look for brackets, swing arms, and tube or panel mounting options that fit your vehicle’s layout (roll cages, engine bays, or trunks).
- Durability and materials: Aluminum or stainless parts resist corrosion and wear, especially in harsh environments.
- Kit completeness: Decide whether you need a full kit with brackets, decals, and linkage or a bare switch to pair with your own hardware.
- Safety labeling: Decals like “Push Off” aid clear operation and reduce confusion during emergencies.
When choosing, consider whether you need a simple single-pole disconnect or a multi-pole system that can isolate multiple power feeds. For vehicles with complex electrical networks, a 4-pole kit that can disconnect both battery and alternator circuits offers the most comprehensive safety.
