MSD 8777 Ignition Timing Retard Module Kit 1-5 Degrees

The MSD 8777 Retard Module Kit provides a complete range of low-degree plug-in timing retard modules for precise ignition timing control. Designed for use with MSD timing controls and ignition boxes featuring built-in timing control, this kit gives tuners the flexibility to dial in the exact amount of timing retard their application demands.

This kit includes five individual plug-in retard modules covering 1°, 2°, 3°, 4°, and 5° of timing retard — ideal for fine-tuning ignition timing on performance engines running nitrous, forced induction, or high-compression setups where small-increment adjustments make a significant difference.

Kit Includes:

• 1° Retard Module
• 2° Retard Module
• 3° Retard Module
• 4° Retard Module
• 5° Retard Module

Key Features:

• Five plug-in retard modules in one convenient kit
• Compatible with MSD timing controls and ignition boxes with built-in timing control
• Simple plug-in installation — no soldering or wiring required
• Covers the 1°–5° retard range for low-increment precision tuning
• Part of MSD's comprehensive retard module lineup (see also PN 8776, 8774, 8775 for higher degree ranges)

Note: This product is intended for racing use only on non-emissions-controlled vehicles. It is against the law to install this part on an emissions-controlled vehicle.
