The Arrowmax AM-910037 Medius MID Belt Tensioner is a purpose-made accessory for controlling belt tension on MID-layout drivetrains found in SERPENT Project 4X cars. Its compact design and indexed adjuster help maintain consistent belt preload across a range of setups and track conditions.

Offered as a direct replacement or an aftermarket upgrade, the unit provides a clear mounting reference and a threaded adjustment interface for small, repeatable changes. The details below explain fitment, installation tips, and why this part matters on belt-driven 1/10 electric kits.

Is installation difficult for hobbyists?

No special skills needed beyond standard hobby tools; take care to note original alignment and thread engagement when fitting the tensioner.

Will this work on tuned race setups?

What should I check after fitting?
