Nissan NI-52730 Ring Gear Stopper

Nissan NI‑52730 – Ring Gear Stopper (OEM Differential Holding & Service Tool)

The Nissan NI‑52730 Ring Gear Stopper is a genuine OEM service tool engineered to securely lock the ring gear in place during differential service, gear‑set installation, and torque‑critical procedures. When working on carrier assemblies, backlash adjustments, or ring‑gear bolt torqueing, even slight gear movement can lead to improper setup, noise, or premature wear. The NI‑52730 provides the stable, positive engagement required to keep the ring gear completely immobilized.

Designed to meet Nissan’s factory specifications, this tool interfaces precisely with the ring gear to prevent rotation without damaging gear teeth or carrier components. It is referenced throughout Nissan service manuals for differential rebuilds, axle service, and gear‑set replacement—procedures where accuracy and stability are essential.

Application: L34 Altima 2.5L engine.
