Dorman 03127 Front Exhaust Stud Kit - 3/8-16 x 1-11/16 in.

Perfect replacement. Installation tip: Drive the old ones out from the bottom with a hammer and a 6-12 inch rod (1/2 inch extension works great). Drop the new studs in place, place a over-sized nut on the stud and then thread the supplied nut on using the over-sized nut as a temporary spacer. Tighten the nut until the head of the stud is seated. Remove nut, return the over-sized nut to your junk drawer and reinstall you exhaust.

Worked perfectly on my 2001 Jeep Cherokee.

bolts hold without having to put a wrench on both sides. great fit

Should be a 5 star set of exhaust flange bolts but they are just an eighth of an inch too short. Took some fanagling to work but my jeep has never been this quiet! Had an exhaust shop hang the exhaust on my 97 4.0 wrangler back 2 years ago. They used regular bolts (not these) and no donut! Jeep always had a leak. Till now. The too short length made this install take an hour longer than it should have. Tap the bolts in using a small hammer with the handle cut to about 5". They wont go in all the way. Put a short socket on them as a spacer and then the nut and tighten down. Then remove the nut and spacer (socket) and check to see if that snugged em down enough.

Perfect fit on my 97 Jeep Wrangler 4.0L 5sp.

I'd recently replaced a rear main seal in a jeep 4.0l. The factory clip on nut/retainers had been getting loose so i figured id replace these. The initiall install I was dreading pulling the studs thru the manifold flanges due to tight work space from underneath. I happened to have plenty of anti seize for the install & theyve yet to back off, thanks!

Does NOT fit Dorman exhaust manifold 674-196. The holes in the manifold are too big. The Dorman manifold comes with new bolts.

Probably will work only with factory exhaust. The flange on my ap exhaust is too thick and the studs didn’t even stick through it.
