IronBox BMW M60 / M62 Underdrive Power Steering Pump Pulley

$
140.00
This IronBox underdrive pulley is designed for BMW M60 and M62 engines to reduce power-steering pump speed during sustained high-RPM operation

Its increased diameter slows the power-steering pump relative to engine speed, helping reduce excessive pump load, fluid temperature and the risk of fluid leakage during drift, track and other high-load use

Unlike a standard-diameter replacement pulley, this component intentionally changes the power-steering pump drive ratio for improved operation at high engine speeds

Main features

  • Oversized underdrive design — reduces power-steering pump speed relative to engine RPM
  • High-RPM protection — helps reduce excessive pump load and power-steering fluid temperature
  • Designed for motorsport use — suitable for drift, track and high-RPM engine builds
  • Factory-position installation — designed to mount in the original power-steering pump pulley location
  • Duralumin construction — provides a strong and lightweight replacement for the original pulley
  • Anodized finish — provides corrosion and surface protection
  • BMW M60 and M62 compatibility — designed around the corresponding hydraulic power-steering pump configuration
  • Designed and manufactured in Ukraine by IronBox

Compatibility

  • BMW M60 engine family
  • BMW M62 engine family
  • Original vehicles and engine swaps using a compatible M60 or M62 hydraulic power-steering pump and accessory-belt configuration

Compatibility must be confirmed by the installed power-steering pump, pulley mounting pattern and belt-drive configuration

M62TU engines and custom engine-swap accessory layouts must be checked before ordering

Not intended for engines or power-steering pumps with a different pulley mounting pattern or belt alignment

Required parts — not included

  • Compatible BMW M60 or M62 power-steering pump
  • Suitable accessory belt for the installed engine and pulley configuration
  • Serviceable belt tensioner and guide pulleys

Kit includes

  • Underdrive power-steering pump pulley — 1 pc

Important installation information

The power-steering pump, accessory belt, tensioner and guide pulleys must be inspected before installation

Pulley alignment, belt tension and clearance around surrounding engine components must be checked after installation

Because the pulley reduces pump speed, steering assistance may be lower at idle and very low engine speeds

The installed pulley must rotate freely without belt misalignment, interference or abnormal vibration before the engine is operated at high RPM

Installation and final inspection must be carried out by a qualified specialist familiar with BMW accessory-drive systems
