Front Long Arm Kit: Optimized Off-Road Performance for Jeep Wrangler JL

Upgrade the front axle of your Jeep Wrangler JL (model years 2018-present) with our Front Long Arm Kit, designed for superior performance and durability in off-road conditions.

Advanced Front Axle Design:

  • 7075 Aluminum Front Control Arms: Constructed from 2-inch and 1.5-inch 7075 aluminum, these front control arms enhance strength and lightness, improving handling and responsiveness.
  • Durable Front Brackets: Made from 3/16″ steel, these laser-cut and precision bent brackets provide robust support and an exact fit for front axle enhancements.

Control Arm Memory: Resilience and Reliability

Our 7075 aluminum control arms feature an extraordinary ‘memory’ quality. This allows them to return to their original shape after impacts, ensuring resilience against rough terrains and reducing the risk of being stranded due to control arm damage.

Full-Width Axle Compatibility and Steel Arm Option:

For complete tire clearance, full-width axles are recommended when utilizing these aluminum control arms. If your vehicle is equipped with factory-sized axles, we offer an alternative steel version of the lower control arms with appropriate bends to accommodate the axle size without compromising performance.

Kit Components for the Front Axle:

  • Front Long Arm Control Arm Sets made from 7075 aluminum.
  • Left and Right Front Frame Brackets designed for the Jeep Wrangler JL.
  • A complete assortment of installation hardware including bolts, nuts, and washers.

Installation and Vehicle Compatibility:

  • Expert Installation Required: This kit demands precision cutting and welding, suitable for those with vehicle modification experience. Detailed instructions are provided for a smooth installation process.
  • Exclusively for Jeep Wrangler JL: This kit is engineered specifically for Jeep Wrangler JL models from 2018 to the present, ensuring an ideal fit and optimal front axle function.

FAQs

Our product lines are designed to offer the absolute most value for your budget. Not every build is the same and we understand that. Our series differ mostly in the components used in the construction of the parts. Our Cruise and Town Series utilizes our high grade flex poly bushings at both ends of the arm, this has proven to be a smooth riding easy to maintain and replace bushing that we absolutely love. Our Camp and Trail Series utilizes 5/16″ wall DOM tubing and incorporates a flexible Johnny Joint at the adjusting end, this series has been our most popular series for all around use, great for daily drivers that want to tear up the trails as well. Our Crawl, Tow, and Track Series utilizes the same 5/16″ wall DOM tubing, but features Johnny Joints at both ends. This series gives you the absolute most out of your suspension. This is great for heavy towing/hauling and extreme off-roading. Also, if the component is straight in these series we will machine these left and right hand threaded for easy adjustment on the vehicle!

We are constantly expanding our product lines to include complete kits, if you don’t see something on the site for your vehicle, reach out to our sales team and we can put something together for you.

Our two main sizes of jam nuts require an1-1/2″ wrench or an 1-5/8″ wrench. Generally speaking the 1-5/8″ jam nuts are used on our lower control arms and the 1-1/2″ jam nuts on our upper control arms and track bars. There are some exceptions, but we do offer a crow’s foot that has both sizes.

Any non-synthetic moly based grease is safe on our products, avoid lithium greases and anything red as this can prematurely deteriorate the internal components of the Johnny Joints and bushings used on our parts.
