Stanceparts Universal Air Cup Kit - Front & Rear

The Stanceparts Air Cup Lift System kit is a perfect combination between air ride and coilovers. With universal air cup kits, you keep the ride quality and performance of your coilovers and have the ability to raise your car with the push of a button. It's a great system for show, track, drift, or daily driven cars. It is basically a pneumatic cylinder that easily mounts on top of your coilover.

Normally you will drive at your lowered ride height without the cups pressurized. In this situation the Stanceparts air cup kit acts like a spacer. Whenever you need to pass an obstacle, such as a speed bump or a driveway, you can apply pressure to the cups and it will raise your car 2 inches (50mm). All valves now include adjustable flow control fittings. This means you can now adjust the speed of lifting and dropping separately from each other. Two valves are now included as well so that the front and rear can be adjusted and operated separately.

The Stanceparts Air Cup Kit will fit on 90% of any brand coilovers with straight springs. However, your coilover must meet certain dimensional requirements, otherwise the air cup lift system will not fit.

Step 1

Clearance

Make sure you have enough clearance around the coilovers. The air cups are 120mm in diameter, and the fitting is 17mm (110mm air cups are available on request).

Springs

The air cups can only be installed on linear springs and will not fit on 'shaped' springs, as shown in the figure. In most situations, it is possible to replace shaped springs with linear springs.

Damper Shaft

Measure the thickest part of the shaft with a caliper, measure below any rings or clips.

Air cups are available for coilover shaft diameters: 12.5mm, 14mm, 15mm, 16mm, 18mm, 20mm, 22mm, 25mm, 40mm, 44mm, 44.2mm, 44.5mm and 45mm.

Spring Diameter

Maximum outer diameter:
99mm (89mm for the smaller 110mm air cups).
Minimum inner diameter:
60mm (57mm on request).

There might be a code on the spring indicating the inner diameter, such as 60, 61, 62, or 65 for ID60, ID61, ID62, and ID65mm springs, which are all fine! For example, "62-200-008" means it has an inner diameter of 62mm.

Step 3

Air Cup Installation

Ride Height

In most cases the air cup will take between 20 and 30mm of height. The stack height of the air cup itself is 20mm but with most coilovers the top hat comes on top of the air cup, this will take around 10mm. If there is enough thread left on the coilovers to lower the springs, it won't be a problem. If not, you will need to install shorter coilover springs.

Spring Adjustment

The lift from the air cups requires droop / rebound from the coilovers. If you don't have enough droop, the air cups can't lift the full 50mm. The damper strut simply will top out before achieving the full lift. If you're using the standard spring rates that came with your coilovers, it should be fine. If you're using higher spring rates, we recommend to use helper springs to get the full lift.
