Low-profile MID tensioner for Project 4X cars

The Arrowmax AM-910037 Medius MID Belt Tensioner is an accessory designed to manage belt tension on MID-layout drivetrains used in SERPENT Project 4X models. The unit prioritises a tight footprint and a controlled adjuster so belt preload stays consistent through setup and running.

Supplied as an aftermarket or replacement piece, the tensioner establishes a defined mounting point and a threaded adjuster for precise, repeatable changes. Below we cover fitment, practical installation advice, and the component's role in belt-driven 1/10 electric kits.

Will this part suit race and club cars?

Yes, its adjustability and compact profile make it suitable for both club running and more demanding race setups when used on compatible Project 4X chassis.

How often should I recheck tension?

Check belt preload after the first run and during routine maintenance; re-tension if you notice looseness or belt slip developing.

Can I use it with other MID kits?

It is specified for SERPENT Project 4X Series and Project 4X PRO EP (SER400032). For other MID-layout kits check mounting compatibility before fitting.

Any tips for smoother adjustment?

Use light thread lubricant on adjuster screws and make small, measured turns while monitoring belt tension to avoid overloading the drive.
