RAM 1500 Rear coil Springs come 3 ways and the REBEL has its own spring.  When installing a Carli 1500 2.5" suspension system the rear spring options should be selectd based on model and need.

The standard Ram 1500 spring included with the 1500 system is ONLY applicable for non Rebel/Off Road Package trucks without the Ram Box of Multi-Function Tailgate. The Rebel Has it’s own springs included with the Rebel system; these will work for standard 1500s with Ramboxes/MFT OR small constant loads. Lastly, we’re offering an HD Spring that will work for Standard 1500s with Ram Box/MFT or around 700lb constant loads or Rebels with Rambox/MFT or 500lb bed-loads.
