Choose the headers for your HEMI build

SKUs: 31002402, 31002602

The 1-7/8-inch package in detail

31002402 uses D-shaped ports, 3/8" laser-cut flanges and the stock bolt pattern. It includes 755872 gaskets, CAS-105067 O2 extensions, BK111 / BK114 bolt kits and the dipstick spacer for 5.7-litre applications; that spacer reuses one OEM bolt.

The 2-inch choice

31002602 uses 2" primaries and 3" outlets, with two 18" and two 6" O2 extensions. Both SKUs require Kooks front connections. These headers are for rear-wheel-drive cars and do not fit AWD applications.
