Driver’s looking to add a bit of “aesthetic jewelry” to their current generation Team Associated vehicle or add a touch of class to their Regulator chassis behind the axle steering link now have a machined titanium option from JConcepts. The 5.5mm balls are precisely machined for optimal smoothness and retain the 2mm hex for installation and removal. Sold in packs of four these bits of billet will also reduce unnecessary sprung and unsprung weight from your chassis (dependent upon where they are used, of course).
