Top Upgrades for Sportsman 850 & 450

Snorkel kit: Moves air intake above water - essential for any Sportsman used near water. Install takes 45 minutes.

High-clearance front A-arms: Adds 2-3" of lift and dramatically improves obstacle clearance. Direct bolt-on for most model years.

Warn VRX 35 winch: Perfect capacity for the Sportsman's weight. Installs on most front bumpers without modification.

Heated hand grips and thumb warmers: Essential for cold-weather riders. Polaris OEM fit or Symtec aftermarket both work well.
