The Core 4×4 upper control arms for the Toyota 4Runner

When you lift your 4Runner, the rake angle can cause your spindle to shift, resulting in a quick loss of caster, even with small lifts. As the factory control arm pivots, it causes a loss of clearance around the coilovers and creates a severe ball joint angle, leading to premature failure.

At CORE, we’ve been hard at work developing our upper control arms to solve these issues. We weld our ball joint cups at an angle to help restore lost caster and provide a more neutral ball joint angle, reducing stress on your joints. We also use greaseable polyurethane bushings with custom-made independent crush sleeves with built-in spacers for ease of installation and improved arm travel. But what sets us apart is our use of ½” plate steel, which allows us to weld our bushings at an offset, providing increased clearance with your coilovers and greater down travel in your suspension.

 

Our kit includes custom-built crush sleeve spacers and detailed instructions for all truck configurations, whether factory height, leveled, or lifted. You can also check out our channel for an informative installation video.

Design Features:

  • 1/2″ Plate steel with welded offset
  • Angled ball joint cups
  • 90 degree grease fittings for easy access
  • polyurethane bushings with custom manufactured crush sleeves

Two-Stage Powder Coating

Our control arms undergo a two-stage powder coating process. First, a zinc primer base coat is applied for exceptional corrosion resistance, followed by a durable top coat available in 10 color choices to match your vehicle’s style.

Every product we sell is manufactured and assembled in Orem, Utah, supporting all American manufacturing.

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.
