Description
A worn or undersized front sprocket kills acceleration and forces your engine to work harder than it should. The Renthal 13-Tooth Front Sprocket delivers aggressive low-end power for the TRX400EX while the case-hardened 655M13 nickel chromium steel construction handles the demands of sand, mud, and high-RPM abuse without sacrificing durability. Self-cleaning mud grooves keep debris from accumulating between teeth, maintaining consistent power transfer and extending your drivetrain’s service life.
