TLR just announced the new aluminium 4mm trailing spindle for the 22. After testing the development team found that the additional trailing in the spindle provides smoother steering input therefore making the 22 a bit easier to drive. The stock spindles on the TLR has 2mm of axle trail. The parts are made out of high-grade aluminium and come anodised for more durability and added looks. Included are also titanium-nitride king pins.
