Tamiya R/C road and off-road racing cars have used traditional ball-end adjusters to secure sway bars. These are brand new designs which integrate adjusters and stabilizer ends (such as those in Items 54757 and 42281). The result is a lighter chassis and improved stabilizer effect, thanks to an effective 4.7mm shortening of the stabilizer bar.  - Stabilizer End 5mm Adjusters x4  - Compatible with stabilizers such as 54757 and 42281.  - NOTE: Adjusters may require filing down when used on some models.
