Finding Air Leaks
STEP 1
Inflate the air springs to 30 PSI (2.1 BAR).
STEP 2
Spray all connections with a solution of liquid dish soap and water. Wait 30 seconds and check
for bubbles, which indicate leaks.
STEP 3
Check the air pressure again after 24 hours. A 2-4 PSI (0.14-0.28 BAR) loss after initial
installation is normal. Retest for leaks if the loss is more than 5 PSI (0.34 BAR).
STEP 4
After checking for leaks, deflate the springs to the minimum pressure required to restore the
system to normal ride height.
Fixing Leaks on Barbed Fittings
STEP 1
If there is a leak at the Schrader valve, tighten the valve with a valve core tool.
STEP 2
If there is a leak at any barbed fitting, cut the air line 1 1/2” (38mm) behind the fitting. Use a
pair of pliers or locking pliers to twist and pull the air line off the fitting. Do not cut the air line
lengthwise at the fitting because this could nick the barbs, likely causing a leak.
STEP 3
Reinstall the air line and air line clamp if the fitting has one. Make sure the air line covers all barbs.
Cutting Air Lines
When cutting air lines, use a sharp knife or hose cutter and make clean, square cuts. Do not
use scissors or wire cutters because these tools will deform the air line, causing it to leak
around fittings. Do not cut lines at an angle.
The maximum bend radius for a 1/4” air line is 1” (25mm). Do not bend the air line more than the
maximum bend radius or side load the fitting connections. Air lines are to be installed straight
into fittings.
