Unmatched Rear Axle Stability Suspension Control

Upgrade your Toyota 4Runner (2003-2024) with the Crawl Series Rear Track Bar, designed to provide exceptional axle centering, improved handling, and superior articulation. Whether you’re conquering tough off-road trails or maintaining control on the highway, this adjustable track bar ensures precise alignment correction and minimizes lateral axle movement for a smoother ride.

Key Features and Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.5” OD DOM Tubing with a 5/16” wall thickness, this track bar provides exceptional strength and durability, surpassing factory and aftermarket alternatives.
  • Forged Joints for Maximum Performance – Equipped with forged Johnny Joints at both ends, this track bar offers unmatched flexibility and vibration dampening while preventing binding during articulation.
  • Left- and Right-Hand Threaded Adjustability – Designed for on-vehicle fine-tuning, this track bar allows for quick and precise axle re-centering and suspension adjustments without removal.
  • Fully Adjustable for Lifted Vehicles – Accommodates 0 to 6 inches of lift, ensuring optimal axle positioning and improved suspension geometry. For lifts beyond 6 inches, contact us for additional solutions.
  • Recommended Pairing – Pair with the Crawl Series Rear Control Arms Set (CRL-T-4R-03-RS4) for a complete rear-end suspension solution, giving you absolute control over axle centering, pinion angles, and suspension geometry.

Two-Stage Powder Coating for Maximum Protection

To ensure long-lasting durability and corrosion resistance, all track bars undergo a two-stage powder coating process.

Zinc Primer Base Coat – Provides superior rust prevention.

Durable Top Coat – Available in 10 custom colors for added protection and personalization.

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.

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!
