Cruise Series Rear Track Bar Compatible with Toyota 4Runner (2003-2024) (CRS-T-4R-03-RTB1)

Maximize Rear Suspension Stability and Control

Upgrade your Toyota 4Runner’s rear suspension with the Cruise Series Rear Track Bar, engineered for superior axle stability, improved handling, and enhanced off-road performance. Specifically designed for model years 2003-2024, this adjustable rear track bar ensures that your axle remains properly centered, even under extreme off-road articulation or lifted applications.

Key Features and Benefits

  • Enhanced Stability and Handling – Keeps the rear axle centered, reducing dog tracking and improving steering precision.
  • Eliminates Axle Shift After Lifting – Adjustable design allows for proper alignment correction when lifting from 0 to 6 inches.
  • Tapered Polyurethane Bushings – Reduces noise, vibration, and harshness (NVH) for a smoother, more controlled ride.
  • Heavy-Duty Construction – Built from 1.5" OD .313 Wall DOM tubing, ensuring long-lasting durability and off-road toughness.
  • Recommended Pairing – For full rear suspension stability, pair this track bar with the Cruise Series Rear Control Arm Set (CRS-T-4R-03-RS4) to correct pinion angles and eliminate suspension deflection.

Precision Alignment and Axle Centering

Lifting a vehicle without an adjustable rear track bar can cause axle shift, negatively impacting stability, tire wear, and overall handling. The Cruise Series Rear Track Bar allows precise axle recentering, ensuring smooth highway control and enhanced off-road performance.

Two-Stage Powder Coating for Maximum Durability

Each Cruise Series Rear Track Bar undergoes a two-stage powder coating process for superior corrosion resistance and long-term durability: Zinc primer base coat for maximum rust protection Durable top coat, available in 10 color options, for added customization and style

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

I met a couple of the Core 4x4 guys at the Salt Lake Offroad Expo and decided to try them out after noticing one of my control arm bushings was disintegrated. I called to discuss parts on Thursday and I was leaving for a trip on Saturday. These guys built my control arms and had them ready to be picked up Friday, 24 hours later. The parts seem to be great quality and they charged me nothing extra to have them painted. These guys were extremely helpful and without them my trip probably would have been cancelled. looking forward to testing out the arms on my next trip to Moab.

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

Very beefy items for a very reasonable price.  Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ.  Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be.  Really have to appreciate a company like this.

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4
