Made for the Tamiya TRF419 series of touring cars is the new suspension upgrade set that allows for a wider range of geometry settings. The lower arm, C-hub, steering knuckle and rear hub set was introduced with the all-new TRF420 but it is also usable with all previous TRF419 kits, the TA07 Pro, TB-Evo.7 and the TB-05 Pro chassis. Included are redesigned lower arms, 4 degree caster C-hubs, 2-piece steering knuckles as well as reinforced rear hubs all of which offer greater precision and durability thanks to a sturdier design and the use of 3mm diameter outer suspension shafts. The lower arms are also of an updated design in the lower shock mounting area with eccentric bushings being used to adjust the damper position, enabling the owner to access additional setup options without having to change the lower arms. Includes in the set is also mounting hardware in the form of shafts, bushings, screws and ball studs.
