HRP aluminum front wheel axle 4mm

TheR31S131 HRP Aluminum Front Axle 4mm fromR31 House is a high-end front wheel axle developed in theHRP by Hayato Yoshibaseries, specially designed forRWD RC drift competition.

Completely redesigned, this axle is intended to deliverultra-smooth rotation, a key factor in improving front end precision and chassis stability in drift.

Machined in Japan with extremely high precision, it guarantees excellentrotational balance and perfect concentricity, reducing vibrations and improving steering feel.

This type of part helps optimize front end behavior, especially on corner entry and during counter-steer phases, where mechanical smoothness plays a crucial role.
