Our lightweight girdle evenly distributes load and dampens harmonics by bolting the main cap studs together to create a super strong rectangular cage. The brace nearly doubles the main web support area in the engine. Securing the loose end of the main studs provides stability unequaled even by a 4-bolt mains setup.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eIn addition, due to the close proximity of the main stud girdle to the crankshaft and rods it also aids in stripping oil off of the crank, which in itself yields a net gain in HP.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eFabricated from 10mm thick high strength aluminium, these girdles are a must for high rpm\/high horsepower applications where block rigidity is critical.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp data-doc-rid=\"6ac7tbbf95c0f1c774badb4d5d6efb683df61\" data-header=\"0\"\u003e\u003cspan style=\"color: rgb(255, 0, 0);\"\u003e\u003cstrong\u003eContents:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e1 X Alloy main cap girdle\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan style=\"color: rgb(255, 0, 0);\"\u003e\u003cstrong\u003eVehicle Fitment Guide\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cimg alt=\"VFG_GIR609\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0901\/5509\/0290\/files\/GIR609-VFG_be6d6378-21ee-4b5e-a262-59870acd577d.png?v=1761279312\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp data-doc-rid=\"6ac7tbbf95c0f1c774badb4d5d6efb683df61\" data-textformat='{\"type\":\"text\"}'\u003e\u003cspan style=\"color: rgb(255, 0, 0);\"\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-doc-rid=\"6dpekd5103c712dd449d0a95ad0124643bd7d\" data-textformat='{\"type\":\"text\",\"bgc\":\"transparent\"}'\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eSpacers from the OEM girdle must be re-used and modified to suit.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-doc-rid=\"6dpekd5103c712dd449d0a95ad0124643bd7d\" data-textformat='{\"type\":\"text\",\"bgc\":\"transparent\"}'\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eMay require sump modifications on some models.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-doc-rid=\"6dpekd5103c712dd449d0a95ad0124643bd7d\" data-textformat='{\"type\":\"text\",\"bgc\":\"transparent\"}'\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eDoes not fit AU type alloy sump without modification.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-doc-rid=\"6dpekd5103c712dd449d0a95ad0124643bd7d\" data-textformat='{\"type\":\"text\",\"bgc\":\"transparent\"}'\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eCustom length main studs are required.
