# Aftermarket Hellcat Jeep Gladiator Conversions Fill Factory Gap Specialty shops offer 700+ HP upgrades as Stellantis delays V8 options - **Source:** [SlashGear](https://www.slashgear.com) - **Published:** 2026-09-17 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/8d5ad4c2-a44a-45ea-aceb-7148a303c0f6 ## Factory power limitations The 2025 Jeep Gladiator currently offers only a 285hp 3.6L V6, despite consumer demand for more powerful options. While Jeep CEO Bob Broderdorf confirmed future V8 availability, the timeline remains unclear. This gap creates opportunities for aftermarket specialists like AMW4x4 to offer high-performance conversions immediately. The standard Gladiator's 260 lb-ft torque proves insufficient for enthusiasts seeking extreme off-road capability. ## Hellcat conversion specs AMW4x4's conversion replaces the factory engine with a supercharged 6.2L Hellcat Hemi producing 707-717hp and 650 lb-ft torque. This nearly triples the stock power output, creating a completely different performance profile. The package requires comprehensive upgrades including transmission, cooling systems, and drivetrain components to handle the increased power safely during off-road use. ## Turnkey package offerings AMW4x4 provides complete Hellcat Gladiator builds starting at $133,855, with premium versions reaching $210,245. These include forged wheels, upgraded brakes, and specialized off-road tires alongside the engine swap. The conversion process takes approximately 65 labor hours, reflecting the extensive modifications required to integrate the Hellcat powertrain with the Gladiator platform. ## Component-level upgrades Beyond the $16,000 crate engine, conversions require a reinforced 8-speed transmission, high-capacity cooling systems, and upgraded fuel delivery. The $60,000 powertrain package addresses these needs with oil coolers, 940W fans, and heavy-duty mounting systems. These prevent overheating and mechanical failure when operating at sustained high outputs in demanding off-road conditions. ## Market positioning AMW4x4 targets enthusiasts willing to pay premium prices for extreme performance unavailable from factory. Their conversions compete with stock vehicles costing half as much, but deliver unique capabilities. The pricing reflects both the expensive components and specialized labor required for such complex aftermarket modifications in the off-road vehicle segment. ## Manufacturer response Stellantis plans to expand Hemi engine availability across Jeep products, but hasn't committed to factory Hellcat Gladiators. This strategic decision leaves room for aftermarket specialists while avoiding potential warranty and reliability concerns. The delayed V8 option suggests automakers prioritize different performance metrics than hardcore enthusiasts. ## Technical challenges Integrating a 700+hp engine into the Gladiator requires addressing heat management, structural reinforcement, and drivetrain durability. The conversion includes ported gearboxes and 8-piston brakes to handle the power. Such extensive modifications demonstrate why most manufacturers avoid factory-installed extreme performance in midsize trucks. ## Aftermarket ecosystem The Hellcat Gladiator conversions represent a growing niche where specialists fill specific performance gaps left by OEMs. Companies like AMW4x4 thrive by offering configurations mainstream manufacturers avoid due to cost, complexity, or market size considerations. This model shows how the aftermarket continues driving innovation in automotive performance sectors. ## Sources covering this story - https://www.slashgear.com/2255790/not-stellantis-americas-most-wanted-aftermarket-hellcat-jeep-gladiator-builds/ — --- _Summary written by Brifing from the original reporting.
