This is a MEUS Racing Isokinetic 3-section CVD Drive Shaft, which can be installed and used in MEUS RACING car axles for Capra 1.9 UTB 1/10 scale car models. Note: If your axle has an "II" or "一" logo, please buy the V2 version CVD. Key Features: This is a MEUS Racing Isokinetic 3-section CVD axle shaft installed inside the car axles for Capra 1.9 UTB 1:10 scale car models. - The Isokinetic 3-section CVD structure is designed for smooth transmission and reduces jerks while turning at a large angle, providing a better driveline system for RC car models. - The 3-section CVD axle shaft features the transmission component called universal joint, the two shafts are connected via one U-shaped buckle to get a larger transmission angle for better flexibility and stability. - This 3-section structure is long-lasting to ensure the longer service life of the whole car axles. - Only for MEUS RACING Capra 1.9 UTB axles with Isokinetic 3-Section CVD axle shaft. US patent (Patent No.: US D1,052,393 S) Isokinetic 3-section CVD ensures that there are no jerks when turning at large angles, 52° max steering angle. Note: 1. If your axle does not have the II logo, please purchase the V1 CVD. 2. If your axle does not have the II logo, it cannot be installed with V2 CVD. 3. If your axle has the II logo, you can use V1 CVD, but you need to buy thicker bearings. 4. These 2 versions of CVD don't work with the CHEAT CODE Capra 1.9 Isokinetic Axles Kit 5. The V1 CVD contains two 5 x 11 x 3 mm bearings. You need to replace the bearing in this position with a 5 x 11 x 3 mm bearing; the original one was 5 x 11 x 4 mm. Package List: 2pcs × Front Axle CVD Shafts; 2pcs × Output Shafts.
