Spear Impulse Aerial Ladder Fire Truck

FiveM Optimized, Lore Friendly Custom GTA 5 Fire Truck Mod

Equip your department for elevated firefighting and rescue with the Spear Impulse Aerial Ladder Fire Truck. This lore-friendly GTA 5 fire truck mod for FiveM builds on the Impulse platform with a longer wheelbase, tandem rear axles and a working aerial ladder.

🚒 Key Features

• Native aerial ladder operation: deploy the outriggers, raise and rotate the ladder, then extend its three telescoping stages.
• Working ladder-mounted water sprayer for elevated firefighting.
• 11 native seats, including positions in the ladder bucket.
• Six-wheel layout with dual rear axles and outrigger stabilizers.
• Custom, fully walkable interior and model-specific non-ELS emergency lighting.
• z_aerial compatibility: developed in collaboration with Zea Developments to make their regular ladder resource compatible with this truck.

🎨 Customization & Liveries

• Native paint customization: combine any included livery with independent body-panel and metal colours.
• Shared Impulse options: the pumper’s base customization and full livery selection, including bumpers, mirrors, trim, antennas and roof equipment.
• Fleet identity: configurable two-digit callsigns from 00–99.

Department liveries include Los Santos Fire Department (standard, Airport, Classic and Classic Airport), Del Perro, Davis, Rockford Hills, Los Santos County, Blaine County, Paleto, SanFire and Roxwood County FD.

🎮 Native Ladder Controls

| Control | Action | | -------------- | ------------------------------------------------------------ | | Hold H | Deploy the outrigger stabilizers. | | Driver camera | Lift and rotate the ladder once the outriggers are deployed. | | Hold Shift | Extend the ladder’s three telescoping stages. | | Hold Ctrl | Retract the ladder. |

Optional z_aerial integration: we worked with Zea Developments to make their regular z_aerial resource compatible with the Spear Impulse Aerial Ladder. Obtain the ladder script and its setup documentation from Zea Developments. Native ladder operation is available independently of this optional integration.

Built for FiveM: a standalone vehicle package, scratch-made by Jack Lonergan and the ONX Studios team. Five LOD levels and optimized textures balance performance with detailed modelling and functionality.
