Setup and Installation
Installation of the RPM 80242 Front A-Arms requires basic tools and familiarity with RC vehicle assembly. Always refer to your vehicle's original manual for specific disassembly and reassembly instructions.
- Preparation: Ensure your vehicle is powered off and the battery is disconnected. Place the vehicle on a stable, clean surface.
- Remove Wheels: Carefully remove the front wheels from your vehicle.
- Disassemble Stock A-Arms:
- Locate and remove the screws or pins securing the stock A-arms to the chassis and the steering knuckles/bearing carriers.
- Note the orientation of all components, including shims and spacers, for correct reassembly.
- Carefully detach the shock absorbers from the stock A-arms.
- Install RPM A-Arms:
- Position the new RPM Front A-arms in place, ensuring correct left and right orientation.
- Attach the A-arms to the chassis using the original hardware. Do not overtighten.
- Reattach the steering knuckles/bearing carriers to the outer pivot points of the RPM A-arms.
- Reattach the shock absorbers to the designated mounting points on the RPM A-arms.
- Note: RPM A-arms feature increased clearance for improved droop travel when used with RPM oversized bearing carriers (RPM #80372 & #80382), which may be purchased separately.
- Reassemble and Inspect:
- Reinstall the front wheels.
- Check all fasteners to ensure they are secure.
- Verify that the suspension moves freely without binding.
- Perform a basic function test of the steering and suspension before operating the vehicle.
Operating Characteristics
The RPM 80242 Front A-Arms are designed to enhance your vehicle's performance and durability.
- Enhanced Durability: Constructed from a specialized nylon blend, these A-arms offer superior resistance to impacts and stress compared to stock components.
- Reduced Unsprung Weight: Being approximately 25% lighter than stock A-arms, they contribute to improved suspension response and overall vehicle handling.
- Optimized Design: The angled leading and trailing edges are engineered to help the vehicle ride over obstacles more smoothly, reducing the likelihood of impacts that could cause damage.
- Increased Droop Travel: The design provides increased clearance, allowing for greater suspension droop when paired with RPM oversized bearing carriers, potentially improving off-road performance.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your RPM Front A-Arms.
- Inspection: After each use, visually inspect the A-arms for any signs of damage, cracks, or excessive wear. Check pivot points for looseness.
- Cleaning: Remove dirt, mud, and debris from the A-arms and surrounding suspension components. A soft brush and mild soap with water can be used, followed by thorough drying.
- Fastener Check: Periodically check all screws and pins securing the A-arms to the chassis and knuckles. Tighten any loose fasteners, but avoid overtightening.
- Pivot Smoothness: Ensure that the A-arms pivot freely without excessive friction. If binding occurs, disassemble, clean, and reassemble the pivot points.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| A-arm feels loose or has excessive play. | Loose mounting screws/pins, worn pivot bushings, or damaged A-arm. | Check and tighten all fasteners. Inspect pivot bushings for wear and replace if necessary. If the A-arm is damaged, replace it. |
| Suspension binds or does not move freely. | Dirt/debris in pivot points, overtightened fasteners, or incorrect assembly. | Clean pivot points. Loosen and re-tighten fasteners to appropriate torque. Review installation steps for correct assembly. |
| A-arm appears bent or cracked. | Severe impact or prolonged stress. | Replace the damaged A-arm immediately to prevent further issues with vehicle handling and safety. |
