Snow blower impeller modification kit 3 blade universal for 2 stage machines Overview This 3 blade impeller modification kit reduces the clearance between the impeller and the impeller chamber wall on 2 stage snow blowers. By tightening that gap the impeller moves more snow with each rotation, improving operating efficiency and snow throwing ability while reducing the chance of clogging. Key benefits Reduces impeller to chamber clearance to improve snow handling and throwing performance. Lowers the likelihood of snow buildup and clogging in the impeller chamber. Durable rubber metal construction resists breakage for long service life. Universal design for use when modifying or restoring 2 stage snow blowers; replaces worn or damaged impeller modification parts.
