Pro-Race Street Harmonic Balancer For Holden V8 253/308 incl. 4.9L EFI

RPI: 2648515 | MPN: 24290

Features

Nodular iron construction over 30% stronger than gray iron.

Bonded Elastomer outer ring and inner hub are bonded (vulcanized) to the elastomer.

Removable counterweights externally balanced models feature bolt-in counterweights, making it easy to switch from an externally balanced engine to a internally balanced engine.

60 degrees of permanent easy to read timing marks (40 degrees on SB Ford models).

PERFORMANCE While PRO/STREET harmonic dampers are not intended for racing, the fact they are cast of nodular iron, as opposed to regular gray iron, means they are suitable for higher RPMs than most competitive models. Note: The PRO/STREET nodular iron harmonic dampers are NOT SFI certified.

DESIGN PRO/STREET harmonic dampers are machined to tolerances far exceeding those used by OEs. This provides great fitment around the bore and oil seal, and a great surface finish.

BONDED ELASTOMER Unlike many OE dampers, or other replacement style dampers, the PRO/STREET range feature a bonded elastomer! The elastomer is injected at high temperature and under extreme pressure. In fact during the manufacturing process EACH AND EVERY PRO/STREET damper is subjected to elastomer bond test of 3000lbs separation force. If there is any sign of bond degradation then the damper is scrapped. Many OE dampers are not bonded at all.

NODULAR IRON Nodular iron, also referred to as ductile iron, is typically the material used for heavy duty applications of cast iron products. It is approximately 30% stronger than regular gray iron. So it was only natural that when PRO/RACE developed the heavy duty OE replacement PRO/STREET dampers, high strength nodular iron was the material of choice.

REMOVABLE COUNTERWEIGHTS Harmonic dampers are supplied in two styles; those for internally balanced engines and those for externally balanced engines. Externally balanced engines have a counterweight bolted into..,ask seller for more info
