This is an RC-scale adjustable upright insert intended for fine tuning the upright geometry on compatible Serpent SRX8 Gen4 GP (SER600024) chassis. The part provides incremental adjustment points to alter suspension and steering geometry without changing the main upright casting.
Installation is straightforward for anyone familiar with basic spindle and upright disassembly: remove the wheel hub area, fit the insert into the upright boss, then reassemble and verify clearance. Keep fastener torque and bearing alignment consistent with the chassis manual to avoid binding.
Functionally this insert is used as a tuning element to modify roll center, scrub radius and steering response in small steps. Use it in setup iterations with track testing to evaluate handling changes rather than as a single "fix" for multiple issues.
