For RC tuners focused on reliability, the XRAY 387561 Nickel-Coated Pivot Ball Set is a straightforward hardware upgrade. Made for M18 and NT18 models, the 5.8mm Type A balls use a nickel finish to help extend service life and keep movement smooth.
The nickel layer gives a hard, low friction surface that cuts down on surface wear and helps the joint move consistently lap after lap. That makes these pivot balls a good choice when you want repeatable steering feel and less frequent replacements.
These pivot balls are intended for use on XRAY M18 and NT18 cars where 5.8mm Type A fittings are required. Installation is straightforward and they help stabilise steering geometry for both race and recreational runs.
