Vehicle Fitment

Supplier fitment information identifies CURT 56407 for compatible:

  • 2018 Jeep Wrangler JL
  • 2019 Jeep Wrangler JL
  • 2020 Jeep Wrangler JL
  • 2021 Jeep Wrangler JL
  • 2022 Jeep Wrangler JL
  • 2023 Jeep Wrangler JL
  • 2024 Jeep Wrangler JL
  • 2025 Jeep Wrangler JL
  • 2026 Jeep Wrangler

Fitment includes various listed 2-door and 4-door configurations, including Sport, Sport S, Sahara, Rubicon and select Unlimited trims depending on model year.

Vehicle Notes

The supplier provides a 25-minute estimated installation time for the individually listed Jeep Wrangler applications.

The supplied fitment data specifically identifies the 2018–2025 applications as Jeep Wrangler JL. For 2026, the supplier lists compatible Wrangler Sport, Sport S, Sahara and Rubicon configurations under Jeep Wrangler rather than explicitly labeling them "JL." For that reason, 2026 compatibility should be verified by exact trim and configuration before ordering.

Some vehicles may require additional products depending on their specific configuration.

Important

The CURT product description mentions that the installed connector can be mounted using a CURT Easy-Mount connector bracket. It does not explicitly state that this optional bracket is included with CURT 56407, so a mounting bracket should not be assumed to be included.

Warranty

CURT specifies a limited lifetime warranty with a 1-year finish and parts warranty.
