Kit Includes:
- (12) 48mm Harden Zinc Coated Stud
- (12) M10 x 1.25 Mechanical Locking Flange Nut
Installation:
-
1. Remove original studs from head. If the old studs are difficult to remove use a penetrating lubricant and let soak overnight before attempting to remove.
2. The shorter threaded portion of the stud will be installed into the head. The stud will be installed in the head hand tight.
3. The locking flange nut will be torqued to 33 Ft. Lbs. LC Engineering headers and exhaust gaskets DO NOT Require the use of any sealant. If a silicone sealant will be used, make sure it is oxygen sensor safe.
Double Nut Stud Installation And Removal Technique:
Simply take (1) 10mm x 1.25 nut and thread half way on the one of the studs. Take the another 10mm nut, then thread that onto the same stud and make sure the 2 nuts are tightened against one another. Now take your box wrenches and put one on the first nut, and the other on the second nut tightening them against one another. After they are locked together, take the one wrench and place it on the nut closest to the block, and proceed to free the stud from the block. Reverse for installation.

Worked great / High quality
Bought these for header install. These are about as long as stock studs. Would recommend tracking down right the right tap to clean out stud holes prior to installment. Feels high quality.

Excellent header stud set
Got the set of 12 header studs for my Nissan SR20DE engine after researching that LCE has the right size that will work: 10mm x 1.25 thread pitch and right 48mm length. Just installed eight of them, the remaining ones are backup. Very fast shipping, and I took advantage of the 10% off Labor day discount on their already good price for the set. Nice to get directions to installing them too.

Exhaust studs, headers
I'm very happy with the exhaust studs & headers I purchased. The quality is top notch & ordering was beyond easy. For the studs, I simply sent an e-mail of what I needed. A short time later, LC called me for my credit payment, with the order all ready. Excellent customer service !
