The JR-OT08 aluminium front upper pivot is made for Kyosho Optima 2016 and fits at the top of the front suspension upright as a single replacement part. It provides a harder wearing pivot surface compared with common plastic originals.
Compatibility is focused on Kyosho Optima 2016; verify measurements if you plan to use this pivot on a different model. Treat the part as an aftermarket spare or hop-up for maintaining or upgrading front suspension assemblies.
Fitting procedure: remove the wheel and steering linkages as required, separate the upright from the suspension arm and remove the existing pivot, fit the JR-OT08 aluminium pivot, then reassemble and check steering geometry and free suspension movement. There are no torque values or a hardware list in this description; check the seller listing to confirm whether screws or bearings are provided.
Performance note: swapping to an aluminium pivot like JR-OT08 will help reduce interface wear and aid alignment retention under load, supporting steadier steering feel and more predictable suspension behaviour during use.
