Dorman03127 Front Exhaust Stud Kit - 3/8-16 x 1-11/16 In. Compatible with Select Jeep Models

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

SAVED MONEY BY USING THIS PRODUCT

Had to get two sets because the first stripped out. Second set I was more carful with and seem to be holding up well. Only been on for a week or two.

Fit perfect. Use an extension and a swivel for the ratchet for easy loosening of the old bolts and tightening the news ones..

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!

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 fine on my 1988 Renix XJ 4.0 when I sheared off one of the old bolts. Bash the old ones out with a big punch or bolt and a 5lb sledge, and bash the new ones back in with the same sledge. Use anti seize on the nut threads if you have some, to make it easier on yourself in the future.

Used then for exhaust pipe.
