Redcat Racing Parts: Front Suspension Arm Guide

The front suspension arm is a critical component in any Redcat Racing vehicle. It connects the wheel hub to the chassis, allowing the suspension to articulate and absorb impacts. Whether you're replacing a broken arm or upgrading for better performance, understanding the different types, materials, and compatibility can save you time and money. This guide covers everything you need to know about Redcat Racing front suspension arms.

Types of Front Suspension Arms

Redcat Racing uses two main front suspension arm designs: A-arms and wishbones. A-arms are the most common, shaped like the letter "A" with two mounting points on the chassis and one at the wheel hub. Wishbones are similar but may have slightly different geometry. Most Redcat models, such as the Everest, Gen7, and Volcano, use A-arms. Check your specific model's manual to confirm the design.

Stock vs. Aftermarket

Stock arms are made by Redcat and are direct replacements. Aftermarket arms come from third-party manufacturers and often offer different materials or geometry. Aftermarket options can be more durable or provide tuning adjustments, but they may require modifications to fit.

Material Choices: Plastic vs. Aluminum

Front suspension arms are typically made of plastic (nylon composite) or aluminum. Each has its pros and cons.

Plastic Arms

Factory Redcat arms are usually nylon composite. They are lightweight and flexible, which helps absorb shocks and reduces stress on other parts. Plastic arms are also inexpensive and easy to replace. The downside is they can break under extreme loads or crashes, especially in heavier trucks.

Aluminum Arms

Aluminum arms are more rigid and durable. They resist bending and breaking, making them popular for hard bashing or racing. However, rigidity can transfer impact forces to the chassis or bulkheads, potentially damaging other components. Aluminum arms are also heavier and cost more. For most recreational driving, plastic arms are sufficient. For competitive or aggressive use, aluminum is a worthwhile upgrade.

Compatibility with Redcat Models

Front suspension arms are model-specific. Redcat's parts numbering system helps identify correct arms. For example, the Everest 10 uses part number RER20725 for the front upper arm and RER20724 for the lower. Before buying, confirm your model and year. Some arms are shared across multiple models. The Gen7 Sport and Gen7 Pro use the same arms, while the Volcano EPX and EPX Pro have different geometry. Visit Redcat Racing's official website and use their parts finder tool to verify compatibility.

Upgrading for Performance

Upgrading front suspension arms can improve handling and durability. Here are common upgrades:

Adjustable Arms

Some aftermarket arms offer adjustable camber and caster via turnbuckles or pivots. This allows fine-tuning alignment for better cornering grip. Adjustable arms are typically aluminum and come with rod ends and ball joints.

Stiffer Materials

Moving from plastic to aluminum or carbon fiber can reduce flex and improve steering response. Follow this with upgraded shock towers or bulkheads to handle the extra load.

Heavy-Duty Options

For monster trucks like the Redcat Kraton or MT10, heavy-duty arms with reinforced ribs or thicker cross-sections prevent breakage from landings. Some brands like RPM and Hot Racing make drop-in replacements.

Signs You Need Replacement

Common signs of a worn or broken front suspension arm:

• Visible cracks or bends
• Excessive wheel play or wobbling
• Uneven tire wear
• Suspension binds or doesn't return to neutral
• Drivetrain noise from misalignment Inspect arms after every hard run. Small cracks can quickly become full breaks.

Installation Tips

Replacing front suspension arms is a straightforward job with basic tools. Here are tips:

Gather Tools

You'll need a Phillips screwdriver, hex wrenches (metric sizes 2.0, 2.5, and 3.0mm), and possibly a small hammer or punch for stubborn pins. Have thread locker (blue Loctite) ready for metal screws.

Steps

1. Remove the wheel and tire.
2. Disconnect the shock absorber from the arm.
3. Remove the hinge pins that hold the arm to the chassis. Use a punch if pins are tight.
4. Note the orientation of any washers or spacers.
5. Install the new arm, ensuring the hinge pins slide freely.
6. Reconnect the shock and the wheel.
7. Check for smooth suspension movement. Adjust if needed.

Torque Settings

For aluminum arms, avoid overtightening. Plastic arms are more forgiving. Use a light thread locker on metal-to-metal connections to prevent vibration loosening.

Where to Find Redcat Racing Front Suspension Arms

Original Redcat parts are available through their official online store or authorized hobby dealers. Aftermarket brands like RPM, Hot Racing, and Integy offer compatible arms. When shopping, look for the specific model number and year. Avoid generic "universal" arms as they rarely fit properly.

Final Recommendation

For most Redcat owners, sticking with stock plastic arms is the best balance of cost and durability. Replace them with genuine Redcat parts to ensure fit. If you frequently break arms, consider upgrading to aftermarket heavy-duty plastic (like RPM) before moving to aluminum. Aluminum is best for competitive use or extreme bashing but requires reinforcing other parts. Always check compatibility and read forums for real-world feedback from other Redcat enthusiasts. A well-chosen front suspension arm keeps your truck running reliably and performing at its best.
