Artec JL4508 Inner C Gussets D30/D44 for Jeep JL Rubicon/JT Rubicon MaxTow

Vehicle Fitment

• 2018-2024 Jeep Wrangler JL Rubicon (Dana 30/44 front axle)
• 2020-2024 Jeep Gladiator JT Rubicon (Dana 30/44 front axle)
• 2020-2024 Jeep Gladiator JT MaxTow (Dana 30/44 front axle)

Fitment Notes

• Jeep uses multiple inner-C casting variants across the JL/JT lineup - JL4508 is specific to Rubicon and JT MaxTow models; JL Sport/Sahara and JT Sport/Overland (US/Canada) use the different JL4506 gusset instead
• If axles have been swapped between JL/JT models, select the gusset matching the model the axle originally came from, not the vehicle it's currently installed in
• Per Artec's official product listing, this kit requires general welding and fabrication skills, and holes on the inner C's must be drilled and tapped for new hardware - some third-party retailer listings describe this part as bolt-on, which conflicts with Artec's own installation instructions; confirm directly with Artec before ordering if this matters for your install plan
• Welding should only be performed by a competent welder; some grinding and fitment adjustment may be required, as individual axles vary slightly

Features

• Heavy-duty design built to take serious abuse and reinforce the front Dana 30 or Dana 44 inner C on JL/JT axles
• 3/16" thick precision cut and formed steel construction
• Precisely contours and wraps around the inner C to add genuine structural rigidity, rather than adding a flat, non-contoured gusset
• Reinforces an area of the axle known to be prone to abuse and flex under hard off-road use

Product Description

The Artec JL4508 is a set of heavy-duty inner C gussets built to reinforce the front Dana 30 or Dana 44 axle on Rubicon-spec JL and JT Jeeps, targeting the inner C - the portion of the axle housing that takes significant flex and abuse under hard off-road driving. Rather than a flat plate bolted or welded over the area, these gussets are precision cut and formed to actually contour around the inner C, adding structural rigidity that matches the housing's shape rather than sitting proud of it.

Built from 3/16" mild steel, the gussets are engineered specifically for the inner C casting used on Rubicon and JT MaxTow models - Jeep uses more than one inner C variant across the JL/JT lineup, so getting the correct part number matched to your specific axle casting matters here. Per Artec's own installation guidance, fitting these gussets involves welding along with drilling and tapping new holes in the C, which puts this squarely in "competent welder" territory rather than a weekend bolt-on project.

This is a fit for Rubicon and JT MaxTow owners looking to reinforce a known flex point on the front axle before it becomes a problem on the trail, particularly those running larger tires or pushing the vehicle hard off-road. Given the welding, drilling, and axle-casting-specific fitment involved, this is best planned as part of a broader axle armor project rather than a quick standalone upgrade.
