The Serpent 500623 Aluminum Rollcenter Spacer is a compact 2mm aluminium component made for the SDX chassis. It installs beneath the differential to shift the roll center and refine handling without heavy modification.
The spacer gives you a quick way to change handling feel; stacking two spacers produces a 4mm rise for more aggressive steering and increased front traction. Keep in mind that higher roll center settings can make the car livelier to drive.
Confirm the spacer locks into the diff area and inspect surrounding plates. Some setups need a rear stiffener tweak to maintain correct alignment and avoid drivetrain strain.
