The XRAY 364113 - Narrow 3-Pad Slipper Clutch Shaft is built to sharpen the performance of XB4 cars. Machined from Hudy Spring Steel, this shaft delivers high strength and consistent wear resistance. Its narrow profile trims rotating mass for improved throttle response and handling on the circuit, making it a solid choice for racers tuning their setups.
Hudy Spring Steel is favoured in the RC scene for its toughness and fatigue resistance. The material receives extra hardening to stand up to frequent racing loads, and the protective black finish helps shield the surface from abrasion and corrosion during regular use.
A reduced shaft diameter lowers rotational inertia, which helps the drivetrain accelerate faster and respond more quickly to throttle inputs. This change is especially noticeable out of corners and on technical sections where nimble handling matters most.
A dependable upgrade for competitive drivers and hobbyists who want a more responsive XB4 without sacrificing durability.
