MCS Chrome Stage 8 Exhaust Nut Mounting Kit for Harley Davidson

It is used to install head pipes to the cylinder head, without the risk of the nuts loosening.
Specially designed washers, held in place with a special electronic clip, are installed around the nut and do not allow the nut to rotate.
This makes it impossible for the nut to loosen on its own, so... guaranteed to never come loose!
The kit includes 4 nuts, 4 clips and 4 special washers.

Compatible with: > Exhaust to header: 84-23 BT; 86-22XL; 08-12XR1200; 87-10Buell XB
