ATI Super Damper Harmonic Balancer B-Series

The ATI Super Damper is engineered to control crankshaft harmonics that factory pulleys and lightweight underdrive pulleys are not designed to manage. Rather than focusing on reduced weight, this damper actively absorbs and dissipates torsional vibration that can lead to bearing wear, oil pump damage, timing instability, and crankshaft fatigue—especially in high-RPM or performance-built engines.

ATI’s proven elastomer-damped, multi-ring design uses precision-tuned inertia rings to cancel harmful vibrations across a wide operating range. This makes it a critical reliability upgrade for engines that see aggressive driving, track use, or sustained RPM.

Key Features

• SFI 18.1 certified for racing and competition use

• Elastomer-damped, multi-ring design for harmonic control

• Helps extend crankshaft, main bearing, and oil pump life

• Reduces timing scatter and accessory drive vibration

• Precision-machined and internally balanced

• Designed to retain factory accessories, including air conditioning and power steering

Weight & Design Intent

• ATI Super Damper weight: 2.6 kg

• Typical OEM crank pulley weight: ~2.3 kg

The additional mass is intentional and functional. Unlike lightweight pulleys, the ATI Super Damper uses its weight in combination with an elastomer-damped design to effectively control torsional vibration, prioritizing engine longevity and stability over minimal weight reduction.

Pulley & Accessory Compatibility

• Machined with the correct crank pulley grooves to work with the factory accessory belt system

• Fully compatible with OEM A/C and power steering

• No accessory delete required for street or track builds

Intended Applications
Designed for Honda B-Series engines, including:

• B16

• B17

• B18A / B18B

• B18C1 (GS-R)

• B18C5 (Type R)

• B20

Common vehicle applications include 1990s–early 2000s Honda Civic and Acura Integra models equipped with B-series engines. Ideal for performance, motorsport, and endurance-focused builds where long-term engine durability and consistency are a priority.
