Ask a question about this product

When the IJSBA rulebook announced that the displacement would be increased to 900cc in the Ski Limited class we went right to work designing a dome that would accommodate this change.   Our Big Bore Limited Dome will accommodate an 84mm to 85mm piston.   Just like our Standard domes our Big Bore Limited domes are machined from billet 7075 aluminum alloy and are hard anodized for corrosion protection.   The .050" step optimizes the piston to dome clearance when using a .060" base gasket.   If a thinner base gasket is used the dome will require machining to prevent piston to head contact.   Available in 26cc, 27cc, 29cc configurations.
