Ever since having been released in July 2003, the Shocker SFT has remained the premier Smart Parts marker, representing top of the line performance and reliability. Shockers have been chosen by the majority of Smart Parts' sponsored teams since their release. The Shocker's popularity also brought along many upgrades and customized versions, available from various manufacturers and developers, similar to its older brother the Impulse. Base-model Shockers currently retail around $700, with the more customized "private label" version around $1000 or more (depending on the model).
