These are our lightest CVA bones yet, crafted from specially treated Ti 6Al-4V grade 5 Titanium alloy for unmatched reduction in rotational inertia. These bones deliver the quick acceleration and deceleration that gives stock racers the competitive edge.

Application: These ultra-lightweight bones are optimized for stock racing, specifically for the 21.5 to 17.5 classes.

Key Features and Specifications:

• Weighing in at just 6.0g for the pair, these bones are 38.78% lighter than the standard bones.
• In-house ultra-high precision tight tolerance swiss machining
• Made from treated Ti 6Al-4V grade 5 Titanium alloy
• Improved acceleration
• Better braking response 
• Increased power transfer 
• Better agility and responsiveness when cornering
• Lower motor temperatures 
• Lower overall vehicle weight
• Laser-etched logos and identification markings

Includes:

• Two CVA bones

Replaces: TLR232138

Fits:

• 22X
• 22 5.0

Disclaimer: This part was originally designed for the 22 5.0, where it fits perfectly. On the newer 22X, it works in the middle and low diff height positions, but not in the high diff height position. In the high position, the longer pins interfere with the camber link mounts. To use it there, you’d need to grind the pins down or clearance the camber link mounts.
We previously pulled this part from the store because of this incompatibility, but we’ve brought it back by customer request for those who don’t run the high diff height.

Team Driver Tip: Use R1WURKS Black WS2 Grease at the joint and drive cup during assembly
