Pioneer Automotive DA-112 Harmonic Balancer

The Pioneer Automotive DA-112 is a replacement harmonic balancer (also known as a crankshaft pulley damper) designed to restore proper engine operation and protect critical engine components. The harmonic balancer is mounted to the front of the crankshaft and serves a dual purpose: driving engine accessories via the serpentine or V-belt, and absorbing the torsional vibrations generated by combustion pulses to prevent crankshaft fatigue and premature wear.

Key Features:

• Direct-fit replacement for the original harmonic balancer
• Engineered to OEM specifications for proper fit and function
• Absorbs crankshaft torsional vibrations to reduce engine stress
• Drives accessory belt system (alternator, power steering, A/C, etc.)
• Helps protect the crankshaft, bearings, and timing components from vibration damage
• Built with durable materials to withstand heat, oil, and engine bay conditions

Pioneer Automotive Products has been a trusted manufacturer of engine and transmission components for the automotive aftermarket. The DA-112 is a quality replacement part suited for professional installations and DIY mechanics alike, helping restore smooth, reliable engine performance.
