JKS Manufacturing Advanced Geometry Upgrade Kit

Jeep Wrangler 07-18 3.8L/3.6L/2.0L

Part #: JSPEC2450

Overview

The JKS Manufacturing Advanced Geometry Upgrade Kit is a precision-engineered suspension enhancement designed specifically for 2007–2018 Jeep Wrangler JK models equipped with 2.5 to 5-inch lift systems. This comprehensive kit addresses common handling and driveline challenges that arise from lifting your Jeep, such as improper caster angles, control arm stress, and bump steer. By restoring proper suspension geometry, it improves steering feel, vehicle stability, and reduces premature component wear.

Ideal for both off-road enthusiasts and daily drivers, this upgrade ensures your lifted Jeep maintains safe, predictable handling characteristics on and off the trail. The kit also optimizes front drive shaft CV joint angles to reduce vibrations and extend drivetrain life, delivering a smoother and more enjoyable driving experience.

Key Features

Combining innovative engineering with durable materials, the Advanced Geometry Upgrade Kit offers superior performance and reliability for lifted Jeep Wrangler JKs:

• Drag Link Flip System corrects steering geometry to eliminate bump steer and enhance steering response.
• JKS6200 control arm relocation brackets reposition lower control arms to correct caster angles and reduce stress on suspension components.
• Compatible with 2.5 to 5-inch lift systems, supporting a wide range of suspension setups.
• Heavy-duty steel brackets provide exceptional strength and long-lasting durability under demanding off-road conditions.
• Included bump stop extensions ensure proper suspension clearance and prevent damage during articulation.
• Optimizes front drive shaft CV joint angles to minimize vibrations and drivetrain wear.
• Maintains factory-like steering feel and vehicle stability after lift installation.
• Precision-engineered components allow straightforward installation and reliable fitment.

Construction & Design

JKS Manufacturing constructs this upgrade kit from premium-grade steel, engineered to withstand the rigors of off-road driving and heavy-duty use. Each bracket is laser-cut and CNC-formed for precise fitment and consistent quality. A robust powder coat finish protects against corrosion and environmental damage, ensuring long-term durability.

The design focuses on restoring proper suspension geometry by relocating control arms and flipping the drag link. This corrects caster angles and steering geometry without compromising ride quality, preserving the Jeep’s handling characteristics even after significant lift modifications.

Installation & Fitment

The Advanced Geometry Upgrade Kit is designed for straightforward installation on 2007–2018 Jeep Wrangler JK models with 2.5 to 5-inch suspension lifts. Installation requires basic mechanical skills and common hand tools, with no major modifications needed to the vehicle’s frame or suspension components. The kit includes all necessary hardware and detailed instructions to ensure a secure and precise fit.

For best results, this upgrade is recommended to be installed alongside lift kits to optimize suspension geometry and driveline angles, enhancing both on-road drivability and off-road capability.

What's Included

• Drag Link Flip System assembly
