Inner C Gussets for Jeep Wrangler JL 2018+ & Gladiator JT 2020+ (Dana 30/44)
These Artec inner C gussets shore up the weakest point of the factory front axle on the Jeep Wrangler JL (2018 and up) and Gladiator JT (2020 and up): the cast inner C's where the knuckles mount. Once you add 35s and start working rock ledges, steering and impact loads flex the junction between casting and axle tube, and alignment slowly walks away from spec. Each 3/16" steel gusset is CNC laser cut, CNC bent, and contoured from 3D scans of the JL/JT housing, so it wraps around the inner C instead of sitting against it as a flat plate. The set reinforces both the Dana 30 (M186) and Dana 44 (M210) front axles, making it a smart first structural upgrade before a full truss.
Features
- 3/16" mild steel, CNC laser cut and CNC bent for precise fit-up
- Wrap-around contour hugs the inner C rather than a flat tacked-on plate
- Reinforces factory front Dana 30 (M186) and Dana 44 (M210) housings
- Shaped from 3D scan files of the JL/JT axle for accurate contours
- Complete set of four: upper and lower gussets for driver and passenger sides
- Weld-on installation for a permanent bond to the housing
- Made in the USA
Order the version that matches your trim: JL4508 covers the JL and JT Rubicon plus the JT MaxTow, while JL4506 covers JL Sport and Sahara, JT Sport and Overland, and non-US/Canada Rubicon models. Installation is weld-on and access around the knuckles is tight, so plan on axle removal and a competent welder. For the rest of the housing, pair the gussets with the JL-JT Apex Front Axle Truss, add 48" Tube Armor underneath, and browse more axle reinforcements and Jeep Gladiator parts.
Inner C Gussets for Jeep Wrangler JL 2018+ & Gladiator JT 2020+ (Dana 30/44) FAQs
Which version fits my Jeep?
Match the SKU to your trim. JL4508 fits the Wrangler JL Rubicon, Gladiator JT Rubicon, and JT MaxTow; JL4506 fits JL Sport and Sahara, JT Sport and Overland, and Rubicon models sold outside the US and Canada. Both sets reinforce the factory front Dana 30 (M186) and Dana 44 (M210) housings.
Do the gussets require welding, and does the axle need to come apart?
Yes, these are weld-on parts, and because each 3/16" gusset wraps tightly around the inner C, plan on removing the axle and moving the knuckles and steering out of the way for clean torch access. This is a job for a competent welder — if you have not welded cast-to-tube joints before, have a professional handle the install.
Why reinforce the inner C on a JL or JT?
The inner C carries steering and impact loads from the knuckle into the axle tube, and larger tires multiply those forces every time the front end hits a ledge. Flex here shows up as wandering alignment and, eventually, cracking. Wrapping the casting with formed 3/16" steel stiffens the joint before that damage starts.
