Rock Krawler JT45AXM-D 4.5" Adventure X Suspension System without Shocks for 20-26 Jeep Gladiator JT Sport/Overland with Diesel Engine
Adventure‑X Mid‑Arm Design: Increases suspension movement while maintaining proper axle placement and predictable steering response.
Tuned for Sport and Overland Models: Designed specifically for non‑Rubicon JT platforms to ensure proper geometry at a 4.5-inch ride height.
Added Clearance Without Long‑Arm Complexity: Delivers improved trail capability and suspension freedom without a full long‑arm setup.
Springs Matched for Height and Control: Selected to support added clearance while keeping the suspension stable and responsive on uneven terrain.
Durable Rock Krawler Construction: Built with quality components intended to handle repeated trail use and long‑term driving demands.
Many states have laws that limit the maximum height of a lifted vehicle. Never exceed the legal height limit.
The Rock Krawler 4.5in Adventure‑X Mid‑Arm Suspension System is designed for Jeep Gladiator Sport and Overland models that require additional clearance and suspension performance for more demanding terrain. Built around the Adventure‑X design philosophy, this system allows increased suspension movement while maintaining controlled axle position and stable steering behavior. Tuned specifically for non‑Rubicon JT platforms, it delivers confident handling as trail conditions become more uneven and technical.
This mid‑arm system provides a capable suspension solution without the complexity of a long‑arm conversion, making it well suited for builds that balance trail use with daily driving. Springs are selected to support the Gladiator’s weight and wheelbase at a taller ride height, keeping the suspension composed under load and responsive over rough surfaces. With durable components throughout, the 4.5in Adventure‑X Mid‑Arm System offers a strong foundation for Sport and Overland owners seeking added capability and reliability.
