Vehicle Information
Polaris Big Boss 400 ATV (1994-1997)
The Polaris Big Boss 400L 6x6, produced from 1994 to 1997, was a robust all-terrain vehicle renowned for its exceptional 6-wheel drive capability and utility. This model was consistently powered by a 378cc liquid-cooled, two-stroke engine, delivering approximately 38 horsepower, paired with a variable automatic transmission offering high and low range. Its design emphasized reliability and performance for demanding tasks. Throughout the 1994-1997 model years, the Big Boss 400L 6x6 maintained a consistent engine and primary trim. While a minor weight reduction was noted from 857 lbs (1994-1995) to 830 lbs (1996-1997), this change did not signify a major generation break or fundamental alteration to the engine or overall design. Regional trim variations existed but were market-specific, not performance-based. Q: How do I ensure I'm selecting the correct parts for my Big Boss 400?
