Big Bore Kits: SLP’s reputation for designing some of the best performing big bores on the market began in 1979 with the creation of a 404 Big Bore Kit for the Polaris TXL 340. Over three decades and many big bores later, this reputation continues to grow tremendously. Our goal has been to design engines that not only provide significant horsepower increases, but also maintain reliability and driveability. The kits listed in this section are fully tested and meet the strict criteria we have set to ensure the highest standards for performance and dependability. Each kit comes complete with tuning recommendations.
