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

Proudly Made in the USA

The Cruise Series Rear Track Bar is manufactured in Orem, UT, using high-quality domestic materials. Our commitment to precision craftsmanship ensures reliable performance and unmatched durability.

Optional Hardware Upgrade

Designed for easy installation using factory hardware, this track bar can also be installed with our optional Grade 8 hardware kits, available separately, to simplify installation on vehicles with rusted or stubborn bolts.

  • Vehicle Fitment: Toyota 4Runner 03-24 – Enhances rear suspension stability, reduces axle shift, and improves steering precision for a smoother, more controlled ride both on and off-road.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

I purchased a upper and lower set of control arms from core 4x4 they came early then expected and seem to be very nice quality I ran into a complication installing them and emailed them my question I was expecting to get the response maybe the next day because it was after hours I got a response in about a few minutes which allowed me to finish the project that day I super appreciate that, the products are good strong lifetime warranty and their customer service is top notch

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

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.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.
