<\/a><\/div>\n<\/figure>\n<\/a><\/div>\n<\/figure>\n<\/div>\nSeveral items indicate a JConcepts equipped vehicle, the Fin turnbuckles are one of those items. Often sampled by the rest of the industry, the JConcepts item is the original, featuring the revolved cuts and delicate machine work. Used by the JConcepts race team including World Champion Spencer Rivkin, and legendary champion Ryan Maifield, Fin turnbuckles are the choice for performance racing applications.<\/p>\n
JConcepts turnbuckle adjustment wrench is offered separately as part #2234<\/a>. The burnt blue turnbuckles have intentional sporadic coloring ranging all around the blue spectrum.<\/p>\n Note: it is necessary to drill the Schumacher ball-cups to at least 3.2mm to properly thread on the latest heavy-duty JConcepts turnbuckles. A light amount of #8119<\/a> RM2 heavy-metal grease can be used on the metal threads to assist threading on the ball-cups after modifications.<\/p>\n Features:<\/strong> JConcepts \u2013 Schumacher Cat PB Fin Titanium turnbuckle set, 7pc. \u2013 Burnt Blue<\/strong><\/p>\n
