Worn bushings can turn a smooth haul into a grinding mess. The RAILBLAZA C-Tug Replacement Wheel Bush Set includes four factory-spec nylon bushes that restore tight, quiet, low-friction wheel performance to your C-Tug kayak cart. These bushings sit between the wheel and axle, keeping everything centered, spinning smoothly, and built to last. Whether yours are cracked, worn down, or long gone, this set drops in fast and fits perfectly—no mods, no guesswork. Made from high-strength, low-wear nylon that handles sand, salt, and abuse without flinching. If your cart’s gotten noisy or sloppy, this is the fix that gets it back in fighting shape.
