Description
A pair of fiberglass-reinforced plastic (FRP) mounts that extend a roller's attachment point further out to the side of the chassis. Widening the roller stance this way sharpens cornering response and adds stability through corners compared with the kit-standard mounting position. The set includes the 830-size ball bearings needed for the rollers themselves plus attachment hardware.
- 2x FRP side extension roller mounts
- 830 ball bearings included
- Compatible with Super-1, Super-II, Super TZ, Super X, Super XX, Super TZ-X, VS, MA, MS and AR chassis cars
- Super-1 and Super TZ chassis require the separate FRP plate from item 15242; some rollers may need chassis modification
