Product Description

Your Polaris Sportsman 800 EFI needs this mud-slinging clutch upgrade for total trail taming

Mud bogs got you bogged down? If your Sportsman 800 struggles to spin those massive 28+ inch tires through the muck, the EPI Mudder Clutch Kit is your trailside savior. This kit transforms your ATV into a mud-churning monster, designed specifically for deep, sticky swamp sessions.

Features to Make Mud Your Plaything:

  • Instant Torque Boost: Reclaim the low-end grunt those big tires stole, so you can pull out of the deepest holes.
  • Belt-Saving Backshift: Say goodbye to slipping belts and burning rubber – this kit grabs and holds for efficient power transfer.
  • Snappy Throttle Response: Feel the instant surge of power when you hit the gas, leaving your buddies stuck in your muddy wake.
  • Built for Brutal Conditions: Designed for elevation up to 3,000 ft., so you can climb out of the muck and rule those muddy hilltops.
  • Effortless Install: Get back to the action fast – the kit includes everything you need for a quick setup.

Frequently Asked Questions:

  • Is this kit too aggressive for casual trail riding? If you mainly ride groomed trails, you might find it a bit too eager.
  • What's the speed difference with this kit? Don't expect top-end gains – this kit's about low-end grunt, not high-speed runs.

Why You Need This Kit:

  • Regain the power to conquer the biggest mud holes.
  • Laugh in the face of sticky, power-robbing mud.
  • Leave your buddies wondering how you got so unstoppable.
  • Upgrade from 'struggling' to 'surging' through the toughest terrain.
