These carb boots fit great and look great and do the job. The issue is that Polaris does not make this carb boot anymore so you have to buy Kimpex or SPI. The Chinese rubber compound has no inhibitors and starts to crack after one season. Dennis Kirk needs push Kimpex to use a better rubber compound specifications. The OEM product lasted 10 years. Kimpex can do better. Please continue to provide the product but offer a step up if possible.
