This is the HPI pair of Alloy Knuckles for the Bullet ST Flux and WR8.
The Bullet trucks and WR8 cars now have a range of hard anodized aluminium parts that will help them look super cool and dramatically increase their durability! The Aluminium Knuckle Set is an ideal way to improve steering for quick response and firm handling. It's also an ideal upgrade to increase the toughness of the vehicle! Use with the Aluminium Front C-Hub Set for a rock-solid front end (HPI108077)!
