The off-road RC car racing scene has changed over the past few years, with turf and carpet racing becoming more popular and grip levels at an all-time high. The engineers inside Team Associated’s Area 51 were quick to answer the 4WD class with the RC10B74 Team Kit, a completely chassis configuration equipped with a long list of features designed to give you the winning edge.
The engineering continues. The B74.1 platform introduces the use of two separate chassis configurations. The B74.1 is the buggy of choice for high-grip carpet or turf track surfaces with its next-generation Octalock 2-Pad high-load, high-capacity, center slipper clutch and optimized carpet kit setup. The B74.1D includes a center differential with 200,000 cSt silicone fluid and an optimized dirt kit setup.
Both kits utilize redesigned, low-profile shock towers with shorter shock shafts and bodies to lower the center of gravity, providing more predictable handling. Also included in both kits are low roll center (LRC) C and D arm mounts, 66mm CVA bones and axles, and 2.0mm G10 fiberglass chassis brace supports, which all add up to making the B74.1 and B74.1D easier to drive, and easier to push hard on all track surfaces.
Setups and tuning parts are interchangeable between the B74.1 and B74.1D. Both versions come with the speed, durability, and lineage expected of a true champion. Choose the configuration that suits your track and conquer the competition!
