Tamiya 51637 TRF420 Precision Suspension Shaft Set (3x25/22mm) SP-1637  [51637]

Stiffen Your TRF420 Chassis

The Tamiya 51637 TRF420 suspension shafts are essential parts for racers tuning their TRF420 chassis. Made specifically for the TRF420, these shafts replace older, thinner pins to deliver a firmer, more predictable handling feel.

Sizes and Material

Supplied in 3x25mm and 3x22mm lengths, these shafts are manufactured from stainless steel for strong wear resistance. The 3mm diameter gives added rigidity compared to previous 2.6mm pins, helping to reduce flex under load.

Grooved Fastening Design

Rather than a flat section, the shafts use a continuous groove for grub screw engagement. That groove makes securing and indexing the shafts easier during assembly or quick maintenance stops.

TRF420 Part Compatibility

These shafts are designed to work with TRF420 D Parts (Suspension Arms), Item 51639, allowing a straightforward swap into existing TRF420 layouts without complex modification.
