Magnus Girdle 4G63 6 Bolt Main

Magnus Motorsports » Products » Engines and Internals » Magnus Girdle 4G63 6 Bolt Main





Did you ever wonder why the 6 bolts never had a one piece main girdle like the 7 bolts? Don’t worry, this piece eliminates the common fretting problem found on the main caps and main bearing wear associated with high revving engines, and more commonly with the 100mm crank engines. The 6 bolt main girdles cleverly help secure the center main to the adjacent mains on your motor. This piece is a must with all high performance engine builds.

Note, this piece must be used in conjunction with main studs, and your block must be align honed.
