Specs At A Glance

Good To Know

Q: Do I need a spring compressor to install these? A: No, these assemblies come pre-assembled with the spring already mounted, so most installations are a direct bolt-in job with basic hand tools. Q: How do I confirm these fit my GMC? A: Check your vehicle's year, model, and RPO suspension code against the OEM numbers listed, since fitment can vary across trim levels and build dates.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
