I'm getting ready to replace stock upper/lower controls arms and was wondering if any/all of them are TTY?

Thanks.

 

No they are not.

 

Thanks.

 

The upper control arm/mount and lower control arm bolts & nuts are all one time use components. Can you get away with re-using them? Yes, however it is not recommended. The Roush wheel hop reduction kit includes all new nuts & bolts for the upper arm and mount and maximum motorsports includes all new bolts & nuts for the lowers. There's a reason for that. The other companies do not include them to keep price down. The bolts are not cheap retail but you can get them at places like Tasca and Tousley for a good price. You can go to Tasca and search through the chassis component breakdown sheets and find the correct part numbers. It has been like this since the 05 cars and continues to be this way now. Ford uses many one time use hardware components on the Mustang.
