Coil overs and rare shocks

If I go with a lift/level qith new coil overs and rear shocks like rough countries N3s, how often would they need to be serviced( recharged with nitrogen)???

 

Rough Country shocks are designed to be economical. I’ve never seen anything mentioned about them being serviceable or rebuildable. They go bad, you replace them.

 

You would just replace those RC units if they lose effectiveness . Depending on use and the quality, shocks last anywhere from 40k miles to 80k before losing enough dampening to need replacement.

 

So many options of lifts, brand, make, budget to high end-low end lifts, etc all under the garage section/suspension threads...Read the feedbacks of members lifts, wheels and tires combo, all there to research... I'm went with Toytec, affordable, solid and true. Rides better than stock... Also, buy once, cry once for a investment your Tundra deserves.. Good luck.
