Jeep JL & JT Steering Upgrade Buyer’s Guide: RockJock vs TeraFlex vs RPM

When it comes to building your Jeep, every component matters. A tall lift, big tires, and heavy-duty suspension won’t mean much if your steering system can’t keep up.

At Clayton Off Road, we know one of the most overlooked upgrades for Jeep JL and JT owners is steering. Bigger tires and tough trails push factory steering far past its limits.

The good news? You’ve got options. In this buyer’s guide, we’ll compare the three heavy-duty Jeep JL/JT steering kits we offer:

• RockJock Currectlync Steering System
• TeraFlex HD Forged Drag Link & Chromoly Tie Rod Kit
• RPM 2.5-Ton Aluminum Steering Kit

Let’s dive into the specs, strengths, and real-world takeaways so you can choose the best setup for your rig.

RockJock Currectlync Steering System (RJ-442100-101)

The RockJock Currectlync is a tried-and-true upgrade designed for long-term reliability.

Specs:

• Backed by a Manufacturer 2-year warranty

What We Noticed:

Final Takeaway

No matter which steering kit you choose, remember: OEM steering parts struggle even with stock tires. Once you add 35s, 37s, or off-road abuse, it’s only a matter of time before something gives.

• RockJock is the tried-and-true workhorse.
• TeraFlex delivers strength with ball joint longevity in mind
• RPM shines (literally) with premium looks and its beefy size
