Prepare to transform your XJ into an off-road beast.
Why Upgrade to a Long Arm Suspension?
Before we get into the specifics of Rubicon Express kits, let's understand why a long arm suspension is such a game-changer for the XJ. The stock XJ suspension, while decent for everyday driving, has limitations when the trail gets tough.
- Improved Articulation: This is the most significant advantage. Longer control arms allow for a greater range of motion in the suspension. This means your tires can maintain contact with the ground even on uneven terrain, providing superior traction and stability.
- Better Ride Quality: Don't think long arms are just for rock crawling. The increased length also improves on-road ride quality. The longer arms create a more gradual arc of movement, reducing harshness and providing a smoother ride.
- Enhanced Stability: By optimizing the suspension geometry, long arm kits improve stability, especially at higher speeds and on challenging trails. This gives you more confidence and control behind the wheel.
- Reduced Axle Wrap: Axle wrap, the twisting of the axle housing under acceleration or braking, is a common issue with lifted vehicles. Long arm kits, especially those with triangulated upper control arms, significantly reduce or eliminate axle wrap, improving power delivery and braking performance.
Rubicon Express: A Name You Can Trust
Rubicon Express has been a leader in the off-road industry for decades. They've earned a reputation for quality, durability, and performance. Their long arm XJ kits are no exception. What sets them apart?
- Robust Construction: Rubicon Express uses high-quality materials and construction techniques to ensure their kits can withstand the rigors of off-road use. Thick-walled tubing, heavy-duty brackets, and durable bushings are standard.
- Comprehensive Kits: Their kits typically include everything you need for a complete installation, from control arms and brackets to hardware and detailed instructions.
- Engineered for Performance: Rubicon Express doesn't just slap together some parts. Their kits are carefully engineered to optimize suspension geometry and maximize performance.
- Variety of Options: They offer different kits to suit various lift heights and driving styles, allowing you to tailor your suspension to your specific needs.
Choosing the Right Rubicon Express Long Arm XJ Kit
Rubicon Express offers several long arm kits for the XJ, each with its own characteristics. Selecting the right one depends on your lift height, tire size, and intended use. Here's a breakdown:
- Lift Height: Rubicon Express offers kits designed for various lift heights, typically ranging from 4.5 inches to 6.5 inches. Choose a kit that matches your desired lift height and tire size.
- Control Arm Configuration:
- Radius Arm: These kits use a single bracket on each side of the frame that connects to both upper and lower control arms. They are simpler to install but may not offer the same level of articulation as a triangulated setup.
- Triangulated 4-Link: These kits use a triangulated upper control arm setup, which provides excellent articulation and eliminates the need for a track bar. They are more complex to install but offer superior performance.
- Budget: Long arm kits are a significant investment. Determine your budget and choose a kit that offers the best value for your money.
Key Features to Look For
When evaluating Rubicon Express long arm kits, pay attention to these key features:
- Adjustable Control Arms: Adjustable control arms allow you to fine-tune your suspension geometry and correct for driveline angles.
- Heavy-Duty Bushings: High-quality bushings are essential for durability and ride quality. Look for kits that use durable polyurethane or rubber bushings.
- Frame Reinforcement: Long arm kits put a lot of stress on the XJ's frame. Look for kits that include frame reinforcement brackets to prevent cracking or bending.
- Crossmember Design: The crossmember supports the transmission and transfer case. Choose a kit with a robust crossmember that provides adequate ground clearance.
Installation: What to Expect
Installing a long arm kit is not a simple bolt-on affair. It requires mechanical skill, patience, and the right tools. While professional installation is recommended, experienced DIYers can tackle the job.
- Preparation is Key: Before you start, gather all the necessary tools and equipment, including a floor jack, jack stands, wrenches, sockets, a torque wrench, and a cutting tool (for removing old brackets). Read the instructions thoroughly and watch any available installation videos.
- Removing the Old Suspension: The first step is to remove the old suspension components, including the control arms, track bar, and springs. This can be challenging, especially if the bolts are rusted or seized.
- Installing the New Brackets: The next step is to install the new frame and axle brackets. This may require welding, depending on the kit. Make sure the brackets are properly aligned and securely attached.
- Installing the Control Arms: Once the brackets are in place, you can install the new control arms. Adjust the length of the control arms to achieve the desired wheelbase and driveline angles.
- Installing the Springs and Shocks: Finally, install the new springs and shocks. Make sure the springs are properly seated and the shocks are securely attached.
Pro Tips from Us:
- Invest in Quality Tools: Don't skimp on tools. A good set of wrenches, sockets, and a torque wrench will make the job much easier and safer.
- Take Your Time: Don't rush the installation. Take your time and double-check your work.
- Get Help if Needed: If you're not comfortable with any aspect of the installation, don't hesitate to seek help from a professional.
- Use Anti-Seize: Apply anti-seize compound to all bolts to prevent them from rusting and seizing in the future.
- Properly Torque All Bolts: Use a torque wrench to tighten all bolts to the manufacturer's specifications.
Common Mistakes to Avoid:
- Neglecting Frame Reinforcement: Installing a long arm kit without reinforcing the frame is a recipe for disaster. The added stress can cause the frame to crack or bend.
- Improper Bracket Alignment: If the brackets are not properly aligned, it can cause binding in the suspension and affect handling.
- Over-Tightening Bolts: Over-tightening bolts can damage the threads and weaken the connection.
- Failing to Grease Bushings: Grease the bushings regularly to prevent squeaking and premature wear.
- Skipping the Alignment: After installing a long arm kit, it's essential to get a professional alignment to ensure proper handling and tire wear.
Maintaining Your Long Arm Suspension
Once your long arm kit is installed, proper maintenance is essential to keep it performing its best.
- Regular Inspections: Inspect the suspension components regularly for signs of wear or damage.
- Grease the Bushings: Grease the bushings regularly to prevent squeaking and premature wear.
- Check the Bolt Torque: Check the torque of all bolts periodically to ensure they are properly tightened.
- Replace Worn Parts: Replace any worn or damaged parts promptly to prevent further damage.
