Why Choose ICS Trailers

Ride height is the main trap with this air spring because the same suspension family can use different configurations. ICS Trailers can compare the old bag markings, photos, mounting layout and suspension details when the replacement is not obvious.

• Use the 165, 190, 228 or 305mm ride-height reference to narrow the correct setup.
• Cross-reference numbers can be compared against the removed bag before ordering.
