- Precision Manufactured Design — Each chassis is precision manufactured to ensure a secure and reliable fit with your ARRMA Kraton 4S V2, eliminating fitment issues and guaranteeing that all components align perfectly for optimal performance.
- Reinforced High-Stress Areas — Extra material has been strategically added to high-stress areas throughout the chassis, providing additional durability exactly where impacts and stress concentrations are most likely to occur during aggressive driving.
- Integrated Lower Gearbox Houses — The chassis features integrated lower gearbox houses that keep the drivetrain protected and properly positioned, contributing to the overall structural integrity and performance consistency of your RC monster truck.
- Integrated Lower Suspension Mounts — The lower suspension mounts are integrated directly into the chassis design, ensuring precise suspension geometry and eliminating movement that could affect handling characteristics during high-speed runs.
- Centre Diff Module Compatibility — This chassis is fully compatible with the centre diff module, allowing you to customise your drivetrain setup to match your driving style and terrain preferences.
- Slipper Clutch Module Compatibility — Full compatibility with slipper clutch modules gives you the flexibility to adjust your truck's power delivery and acceleration characteristics for different driving conditions.

Frequently Asked Questions
- Is the ARRMA Composite Chassis - XLWB V2 a genuine replacement part? — Yes, this is an official ARRMA part (Z-ARA320799) manufactured to the exact specifications required for your Kraton 4S V2. It replaces the previous ARA320640 chassis and represents the latest evolution in ARRMA's chassis design, incorporating reinforcements in critical areas for improved durability.
- What ARRMA models is this chassis compatible with? — This XLWB V2 chassis is specifically designed for the ARRMA 1/10 Kraton 4X4 4S V2 BLX Speed Monster Truck RTR, available in both the standard and green editions. Always verify your specific model matches C-ARA4408V2T3 or C-ARA4408V2T4 before ordering.
- What is the difference between XLWB and MWB chassis? — XLWB stands for extra-long wheelbase, whilst MWB refers to mid-wheelbase configuration. The XLWB provides a longer wheelbase which improves stability, traction and weight distribution, making it particularly valuable for maintaining control during high-speed running and aggressive cornering on varied terrain types.
- How difficult is it to replace the chassis on my RC monster truck? — Chassis replacement is a straightforward maintenance task for anyone familiar with basic RC work. You'll need to transfer your drivetrain components, suspension parts, and other mounted systems from your old chassis to the new one. The precision manufacturing ensures perfect fitment without any modification required.
- Can I use this chassis with different drivetrain modules? — Yes, the XLWB V2 is compatible with both the centre diff module and slipper clutch module systems, giving you flexibility to configure your drivetrain according to your driving preferences and the terrain you're running on.
- Is this suitable for beginners? — This is a replacement chassis component designed for users who already own an ARRMA Kraton 4S V2 and need to repair or replace their existing chassis. It's not a complete ready to run RC system, so it's intended for intermediate and advanced RC enthusiasts who understand how to install and configure chassis components.
- What material is this chassis made from? — The chassis is constructed from composite material, which provides an excellent combination of strength, durability and weight efficiency. The composite construction resists impact damage better than some plastic alternatives whilst maintaining the precise tolerances required for reliable performance in a brushless RC monster truck.
