So, you want a fancy digital ride height controller, but you don’t wanna deal with ride height sensors? Air Lift Performance has you covered with their 3P system! Here’s what you get with our Stage 3 package. Slam Specialties SS6 front air bags – these front suspensions are tight for space, and these’bags fit perfectly. Air Lift Performance 3P control system. 4-path manifold, water separator, pressure relief valve, and a beautiful handheld controller to top it all off. Front and Rear Airbag Mounting Brackets. The front brackets weld to your frame, and the rears weld to the side of the notch and on top of your axle. 8-piece Weld-in Frame Notch Kit. This notch is big enough to lay 22 wheels, and is stronger than the section of frame it replaces. Viair 480C chrome air compressor. Big enough to keep your air tank filled up, small enough to work with your factory alternator and battery. 5 gallon aluminum air tank. The right size tank to fit under your bed, and enough air to lift you up without waiting. DOT-approved air line and fittings. We don’t cheap out on our plumbing. Only the highest-quality fittings and line to give you a leak-free system. Pre-wired for one of the easiest installations I’ve ever seen. Connect battery power and ground, ignition lead, and compressor wires, and that’s it! Complete plumbing and wiring diagrams. We try to make your life easy, but if you have questions we’re always happy to help! With a pressure-based system, you trade off some accuracy for simplicity. Air pressure isn’t always equal to height, so in some situations you’ll end up needing to manually adjust your vehicle to level it back out- like if you have the trunk/bed loaded down, a REALLY heavy passenger, etc. This is only common in extreme situations- for most day-to-day driving a pressure-based system will keep you rolling just fine. On any car or truck with a leaf spring rear suspension, we always recommend replacing the leaf springs with a 4 link.
