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.

Each rebuild kit includes all necessary components to replace and restore wearable parts.

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

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!
