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.

  • CORE Advantage: Keeps the rear axle centered, improving handling and eliminating dog tracking, while ensuring smooth, stable performance in lifted and off-road applications.

  • Adjustability: Fully adjustable for lifts from 0 to 6 inches, allowing for proper axle centering and suspension alignment correction for enhanced control and drivability.

  • Construction: Built from 1.5" OD .313 Wall DOM tubing with tapered polyurethane bushings to reduce NVH (Noise, Vibration, Harshness) while ensuring maximum durability, off-road toughness, and a smooth ride.

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)
