Sooner or later, you’ll need to add nitrogen to either shock reservoirs or bump stops. Kartek Off-Road offers a regulator and hose that’s configured for this exact purpose. To make pressure adjustment exactly right, Kartek’s suspension pressure gauge provides rugged precision. The Kartek pressure gauge’s body is made from billet aluminum, and the gauge is liquid-filled. The liquid filling means the gauge can withstand accidental jolts and bumps inside a toolbox without losing accuracy. Pressures up to 400 psi can accurately be measured and adjusted.
