Pro-Line PRO643301 PowerStroke Shock Rear Shaft Replacement

The Pro-Line® PRO643301 PowerStroke Shock Rear Shaft Replacement is a genuine replacement rear shock shaft for Pro-Line PowerStroke shocks on compatible RC vehicles. The shock shaft is a high-wear component — it cycles through the shock body thousands of times under load, and is vulnerable to bending, scoring, and pitting from impacts, debris, and hard landings. A bent or damaged shock shaft causes inconsistent damping, oil leaks past the shaft seal, and ultimately shock failure. Replacing the shaft restores correct shock function and extends the service life of your PowerStroke shock bodies. A cost-effective rebuild option versus replacing the entire shock assembly.
