Standard Ignition AL-5390P Ignition Contact Set

Ignition Contact Set for Primary Ignition Service

Standard Ignition AL-5390P is an ignition contact set built for primary ignition service where accurate switching and stable distributor operation matter. It is a direct-fit points-style replacement for vehicles that use a conventional breaker point ignition system, including applications such as Ford and Chevrolet models listed in interchange references.

Key Features

• Pre-aligned and pre-adjusted to reduce setup time during installation
• Lubricated felt pad helps lubricate distributor cam lobes and reduce rubbing block wear
• Ventilated tungsten contacts, where available, run cooler and resist erosion
• Copper-alloy shunt improves conductivity and resists breakage from arm flexing
• Contents: Points
• Standard Ignition AL-5390P is backed by a manufacturer with long-standing ignition expertise

Detailed Description

This ignition contact set is engineered for breaker point distributors that require consistent opening and closing action to maintain ignition timing and spark delivery. The pre-adjusted design helps simplify service work, while the lubricated felt pad supports cam lobe lubrication to limit wear on the rubbing block. Standard Ignition AL-5390P also uses tungsten contacts and a copper-alloy shunt to support electrical performance and durability in primary ignition systems. This part cross-references A121 and AL1041M for the same application.

What It Helps Address

• Hard starting caused by worn or misadjusted points
• Rough idle from inconsistent distributor switching
• Ignition misfire related to contact erosion
• Premature rubbing block wear from dry distributor cam lobes
• Electrical interruption from a fatigued point-set shunt

Installation Notes and Tips

Verify distributor type and point-set application before installation. Set dwell and ignition timing to the vehicle service specification after installation, and inspect the distributor cam, cap, rotor, and condenser at the same time. For fitment-based searches, this part is commonly referenced for Ford and Chevrolet breaker-point ignition service, including Standard Ignition AL-5390P and AL-5390P replacement searches.
