DYNEST Street Spring Bushing Sampler

Find your feel. One pair each of DYNEST Street Spring Bushings in Soft Orange 60A, Medium Purple 70A and Hard Green 80A, for TKP street trucks (roadside cone 0.40 in, boardside barrel 0.50 in). The Shore A number is the hardness of the urethane only, not the feel. The spring cast inside, and how tightly the urethane is confined as the coils close, set the resistance, so a 70A DYNEST does not ride like a 70A conventional bushing. Every grade starts easy and gets firmer the deeper you lean. Ride all three, keep the grade that fits, and keep the others as spares. Installs with standard hardware, no lubrication. Hand-cast in small batches. Patents pending: US 18/785,017; US 19/794,207.
