Exhaust Port Fasteners

• Consists of specially formulated and machined head port bolts designed to interference-fit with special ‘E’-clip locks and custom patterned offset washers

• The bolt holds the pipe secure, not merely by thread tension but by clamping the pipe to the head by wedging the patterned washers against the pipe while the washers are, in turn, wedged between the pipe and the ‘E’-clip locks fitted to the bolt heads

work very well

 theark5 Posted:

fast and what I needed

 cudajim Posted:

You never have to worry about the bolts coming loose when locked with this item. I have been using a few years now

 audrey05 Posted:

If your working on a Shovelhead, this is the only way to go for a" worry free" tight and secure exhaust bolt. Easy install and perfect fit. Hoot, Maryville, TN.

 Anthony Hunter Posted:

well made product very happy

 wa7zcz Posted:

haven't had a need for these yet but they are solidly made and appear to be good quality.

 bhoneck Posted:

as expected

 blowry Posted:

Could use a diagram or exploded view of how it works but figured it out in about 20 min. Works ok but limits how tight you can get the bolts. I doubled up on gaskets for them to work.

 DIANE1402 Posted:

The gaskets and fasteners fit perfect and completly took care of my reocurring problem with the header loosening up.

 Aerowrench Posted:

This product works! Final solution to lost exhaust bolts. Easily removed for maintenance.
