I would look to someone that has experience with coilovers just for piece of mind. Also buying a gauge to check them yourself is a good idea. That way you know for sure what the shop has put in them and over time periodically checking them to see where they are at or any leaks ect..

 

Don't just buy a gauge, you need a special no loss type so you don't loose any more air then you have too. The shocks don't have much in there and even a slight loss can drop the pressure. Your best bet is to just buy a nitrogen fill kit. It is really something anyone that is running coil overs or ORI struts should invest in. Swapping coils is generally needed to set up for ride quality and height. For any of you that has more then 2" of preload on the shocks should be really looking at the coils and running either a longer coil or a higher coil rate.

 

Any recommendations on nitrogen fill kit and no loss gauge?

 

Both king and ORI have the no loss gauges and you can likely find the parts at your local welding shop. Power tank has a full kit you can buy as well with the tank.

Well i would like to thank everyone for the input, but i figured out part of the problem...The track bar bolt was hitting the Bump Stop extension from EVo...turn the bolt around and also added a bit more preload to the rear...it still kind of hits when i bounce on the bumper but not as bad as before...i am going to grind the Bolt head a bit and round the bump stop inwards a bit to clear the bold...I am running Rock Krawler Xfactor control arms set and it pushed the axle back about an inch. i will also check the nitrogen fill..thanks for the info...
