MSD Solid State Relay

This is a great relay at a heavily discounted price. We used it to trigger our Transbrake, Methanol Interrupt Switch, Two Step, Boost Launch Feature, etc. One of the input screws is a little loose, but there are several work arounds to make a firm connection, or you could just completely bypass the one input that has the loose screw. Choice is completely yours. 

MSD Part Number: 75643

Clean up your wiring with an MSD Solid State Relay Block. This module takes the place of 4 standard relays and eliminates unsightly wiring. 4 independent channels can be activated using either power or ground. Each channel is capable of handling 50 Amps for up to 8 seconds or 20 Amps of continuous current. 

🟡Yellow Dot: Perfect for the adventurous! These parts worked when we pulled them, but the backstory (like part numbers) is a bit of a mystery. Buyer discretion advised—grab them for 70% off retail.  

The Fine Print All Sales Final: No take-backs, refunds, or exchanges.  

As-Is Condition: We inspect every part before it hits the listing, but we recommend you double-check compatibility with your project.
