Description
OEM fork seals wear out, allowing oil to seep past the wipers and degrading suspension performance over time. These LEAKPROOF SEALS replacements use a premium Buna-N compound engineered to handle four times the pressure rating of factory seals while reducing stiction and friction for a smoother, more responsive fork action. Install them in minutes with hand tools—no special equipment required.
