No heli-coil, the threads are very strong on these. About 75% thread vs a 65% standard. This material is tough billet, not like cast crapola.
If you put ant-seize on the threads it help from gahling the threads up too.
I have had mine on since late last fall with no issues.

 

No problems with mine. Had them on since last fall also. Good looking and no more wheel hop. I like'm!

 

Thanks for the plug sir.
I may have to do that Heartbeat for you on an exchange basis.

 

Looks Awesome man!!....PM'ed you for prices.

 

man that is awsome!, can you do the z71 logo?

 

Nice work. Any pics installed?

 

I can do any logo if I draw it up on cad first.
These are install and logo samples.
The actual part engraving looks better, the sample plate was milled off with a crappy face mill.
The install pics are from my truck, these were the first set made and are not as beefy as the newest ones.
Pm me if you need more info guys.

 

I don't see that hearbeat amongst your samples.

 

I will hook you up when I get back home man..........Gauranteed!

 

No need to hook me up with anything!!! Just kiddin a bit.. and suggesting that the heartbeat might be a good logo to offer.
