How accurate are aftermarket cross-references?

Cross-references on Airspring are validated against published OEM dimensions: collapsed height, max diameter, max stroke, load rating, mounting interface and operating temperature. Always verify the application before fitment.

Will aftermarket equivalents void OEM warranty?

Aftermarket air springs that match or exceed OEM specifications generally do not affect commercial vehicle warranties beyond the OEM warranty period. Check with the vehicle manufacturer for specific clauses.
