Fits all models of Husqvarna for years 1975-1977. Replaces the rubber elastomer bushings in the early GP models and is also an oem replacement in the later GP models. Each bearing assembly kit is enough to convert 1 swing arm consisting of everything you see in the picture. 2 hardened stainless steel races, 4 high quality needle bearings and 4 rubber O'rings. These easily outperform the elastomer bushings. Don't waste big money on shocks if you don't convert the elastomer bushings to needle bearings. $120 per kit. If you don't want to do the conversion yourself, I will do it for $50 plus return postage.
