R1WURKS R1B Ultra-lightweight Titanium CVA Bones w/ Ball Bearing Barrel, 69mm
We’ve spent months developing and refining this upgrade alongside our race team, validating its performance through consistent winning results. Most recently, it was used as part of Dominic Paccione’s R1B race package during his TQ and overall win at the ROAR Off-Road Nationals in demanding race conditions. After extensive real-world testing and proven track performance, we’re proud to now offer this upgrade to our customers.
Unlock hidden power in your drivetrain with a CVA barrel that utilizes precision ball bearings.
Conventional barrels lose energy through friction and resistance as metal surfaces slide against each other. Our ball-bearing design replaces that sliding motion with rolling contact, which dramatically reduces friction.
In addition to the friction-reducing advantages of the bearing barrels, these components are made from specially treated Ti-6Al-4V Grade 5 titanium alloy. This material delivers exceptional strength while significantly reducing rotational inertia. The result is faster acceleration and efficiency, giving stock racers a competitive edge.
Fits:
- R1B
Key Features and Specifications:
- Weighing in at just 5.76g for the pair, these bones are 40.40% lighter than the standard bones and barrels.
- Serviceable and rebuildable
- 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 overall vehicle weight
- Laser-etched logos and identification markings
Includes:
- x2 R1B Titanium Bearing Barrel CVA Bones
- x2 Ball Bearing Barrel Axles
- x4 Ball Bearing, 3/32" × 3/16" × 1/16"
- x4 E-Clip, 1/16"
Note:
- Bearing barrels are not compatible with kit CVA shafts.
- R1B CVA bones are only compatible with R1B differential outdrives.
- These ultra-lightweight bones are optimized for stock racing, specifically for the 21.5 to 17.5 classes. Not recommended for modified.
