I'm looking to buy some headers in a couple weeks and came across the summit headers, but they say they are for 4WD. Would these work on a 2WD? If not I'll just have to go for a different set.

 

4WD headers in general won't work as there's many Co's making them long & short tube ones. 2wd trucks do have issues with the in frame gas tank. So unless you can get free shipping for returning them it may cost more then what you'll want to spend. May a loco muffler shop can help you if you can't get the right answers for some or p/n ..orich
