The RPM Rear Lower A-arms (81722) are reinforced rear suspension arms, designed for ARRMA 6S V5 & EXB models. They are an improved version compared to the factory ones, offering increased durability, reduced deformation, and more stable suspension behavior.

Main Features

• Reinforced construction with +30% thicker support beams
• Made from high-strength engineering nylon
• New design compatible with V5 & EXB geometry
• Second shock mounting position

Performance & Behavior

• Reduced flex for more predictable handling
• Increased resistance to impacts and heavy use
• Possibility for lower setup through the second shock mounting position
• Improved stability at high speeds

The lower shock position contributes to a lower center of gravity and better cornering.

Construction

• Injection molded from durable nylon with high elasticity
• Designed to absorb shocks without breaking
• Suitable for intense bashing

Compatibility

• ARRMA Kraton 6S
• ARRMA Notorious 6S
• ARRMA Talion 6S
• ARRMA Fireteam 6S
• ARRMA Outcast 6S

Replaces

• ARRMA ARA330654 (V5 / EXB)
• ARRMA AR330249 (V4 and earlier)

Version Notes (important)

• V5 / EXB: use the inner positions (stock geometry)
• V4 and earlier: use the outer positions
• Do not mix incorrect positions without corresponding setup adjustments

Package Contents

• 1 x Rear Lower Arm (Left)
• 1 x Rear Lower Arm (Right)

Ideal upgrade for those who do bashing and want increased durability without sacrificing suspension geometry.
