In 1948 the speedway team Griparna (English: the Griffins) started to race in the Swedish leagues.
1951 the team changed name to Smederna (English: the Blacksmiths) and started to race all home matches in Eskilstuna.
In the spring of 1976 Smederna and the whole town of Eskilstuna was hit by a big tragedy when local superstar Tommy Jansson crashed to death in a world championships qualification at Gubbängens IP, Stockholm.
In spite of the tragedy Smederna continued to be one of Sweden’s best speedway clubs for a couple of years with the gold medal in 1977 as best result.
In 1993 Smederna had once again advanced to Elitserien and this time the team finished on second place which was the best result in ten years.
In the recent years Smederna has struggled with financial problems which forced the club to downsize the squad and release a few top riders like Nicki Pedersen, Billy Hamill and Scott Nicholls.
The club returned to significant success when they won the league title three years running from 2017 to 2019 and again in 2022.
