The Samix SCX-6 7075 Aluminum Steering Knuckle set is a machined aluminum option that uses a larger 8x19x6mm outer knuckle bearing to help increase durability and add weight down low. The design allows use of an optional faux brake rotor (SAMSCX6-6412 - not included) to add scale details to the SCX6.  

Features:

• Heavy duty 8x19x6mm outer bearing improves durability and adds weight down low
• Machined from 7075 aluminum
• More rigid and increased durability
• Optional brake rotor (SAMSCX6-6412) adds scale looks (not included)
