4.0 headers on a 2.9

Cheezno6 · Mar 8, 2010

Hello, all. I bought a set of BBK headers for my wife's 91 Explorer 4.0 4x4 years ago and never used them. My question is would these bolt up on a 88 ranger 2WD with a 2.9? I know from reading FAQ on the 2.9 that the 4.0 is a direct decendant to the 2.9 but didn't know if the exhaust port configuation had changed.

Thanks

Sorry, they're different. You might sell them, tho.

OK for sale now NOS never been used chrome BBKs with hardware and Y pipe, make me an offer

Got your PM, still doing some research

Man the pace setters look similar for the 88 Ranger 2.9 2wd and 91 Explorer 4.0 4wd
