The Cometic StreetPro top-end gasket kit for the Nissan RB26DETT covers an 86mm bore and includes a .027-inch MLS cylinder head gasket. StreetPro kits are positioned for budget-minded street builders and supply the necessary gaskets and seals for a rebuild. Kit materials emphasize quality with MLS, AFM, aramid fiber and Armor Clad components so the top-end assembly uses matched, application-focused materials.
