Why CA Tech USA’s Defender Long Travel Control Arm Kit Is the Best on the Market
If you want to turn your Defender into a confidence-inspiring, big-hit-capable machine without sacrificing streetability or day-to-day drivability, CA Tech USA’s Defender Long Travel Control Arm Kit is the upgrade that does it all. Designed by people who race, fab, and test in the real world, this kit isn’t a bolt-on of convenience — it’s a complete re-think of the suspension geometry for modern long-travel performance. Here’s why it stands above the competition.
1. Purpose-built geometry that actually works
Many “long-travel” kits throw more length at the arms and hope for the best. CA Tech starts with suspension geometry — control arm length, caster, roll center and anti-squat — tuned to keep tire contact, reduce bump steer, and preserve predictable handling through full travel. That means more usable travel, better traction, and less mysterious handling when things get rough.
2. Engineered for strength and longevity
The arms are CNC-formed and MIG-welded from 11 Gauge Steel, so the kit survives real abuse — hard landings, rocks, and repeated off-road punishment. Critical load points are reinforced with gussets and strategic bracing, so you aren’t buying replacement arms after a season.
3. Precision fit and finish — less time in the shop
CA Tech’s arms include precisely machined mounting points and brackets for a near plug-and-play experience. That reduces installation time and minimizes odd alignment surprises after install.
4. Thoughtful end-to-end design
CA Tech thinks beyond the arms: they consider shock clearance, CV boot protection, sway bar link geometry, and integration with common spring/shock combos. The result is a kit that integrates into a real build without unintended compromises.
5. Backed by testing and customer support
A great part is only as good as the company behind it. CA Tech’s support, fitment and Lifetime Warranty plus replacement-part availability mean you’re not left holding the bag if an issue arises.

Final thought — why this kit?
What makes CA Tech USA’s Defender Long Travel Control Arm Kit the best isn’t one single shiny spec — it’s the combination of engineered geometry, heavy-duty construction, quality components and thoughtful integration into the vehicle. The kit was built by fabricators and tuners who understand how a Defender behaves when it’s pushed, and that real-world focus shows in ride quality, reliability, and performance.
