The Serpent 500623 Aluminum Rollcenter Spacer is a lightweight 2mm aluminium shim tailored for the SDX chassis. It sits beneath the differential to move the roll centre and allow controlled handling adjustments.
Stacking spacers gives a straightforward way to increase lift in 2mm steps, with two spacers yielding a 4mm rise. This normally enhances front-end bite and quicker turn-in but can also reduce high-speed stability if overused.
Ensure the Serpent 500623 locks firm in its mounting location and check that the differential height and plate spacing remain correct. A small rear stiffener tweak may be needed for some setups to keep the driveline aligned.
