Key Features

• Universal Application: Designed for broad compatibility with most trucks, classic cars, hot rods, and rat rods, ensuring a safe and quality ride experience.
• Optimized Suspension Geometry: The parallel 4 link and Panhard rod design provides crucial clearance inside the frame rails, prevents gas tank interference, and maintains a consistent pinion angle by precisely positioning the rear axle.
• Heavy-Duty Construction: All steel bars are powder-coated for rust resistance. They feature a 1.25" outer diameter DOM tubing with a .156" wall thickness. Metal brackets are .197" thick, and zinc-plated ends with urethane bushings ensure long-lasting durability.
• Comprehensive Package: Includes 4 steel bars, a Panhard bar, rod ends with urethane bushings, steel axle mounts, frame mounts, steel center link axle mounts, and 5/8" hex head hardware with nylon nuts.
• Adjustable Panhard Bar: The Panhard bar is adjustable from one end, allowing for fine-tuning of the rear axle's lateral position.

Installation Guide

Installation of a 4-link suspension kit requires advanced mechanical knowledge and specialized tools. It is highly recommended that installation be performed by a qualified professional to ensure proper function and safety. Incorrect installation can lead to severe vehicle damage or personal injury.

General Steps (Consult a professional for detailed instructions):

1. Preparation: Safely lift and secure the vehicle on jack stands or a lift. Remove existing suspension components as necessary.
2. Mounting Brackets: Install the steel frame mounts and axle mounts. These may require welding or drilling, depending on your vehicle's chassis. Ensure precise alignment for optimal performance.

5. Final Checks: Double-check all fasteners for tightness. Ensure there is adequate clearance for all suspension components throughout the full range of motion.
6. Alignment: A professional wheel alignment is crucial after installation to ensure correct vehicle geometry and safe operation.

Setup

Proper setup is critical for optimal performance and safety. After initial installation, the suspension system will require fine-tuning.

• Ride Height Adjustment: If your vehicle uses adjustable coilovers or air springs in conjunction with this kit, adjust the ride height to your desired specification, ensuring adequate suspension travel.
• Pinion Angle Adjustment: The 4-link system allows for adjustment of the pinion angle, which is crucial for driveline longevity and smooth power transfer. This should be set by a professional using an angle finder.
• Panhard Bar Adjustment: Adjust the Panhard bar to ensure the rear axle is perfectly centered under the vehicle. This prevents lateral shift during suspension travel.
• Suspension Travel Check: Cycle the suspension through its full range of motion (with the vehicle safely supported) to check for any binding, rubbing, or interference with other vehicle components.

Operating Considerations

Once installed and properly set up, the maXpeedingrods Parallel 4 Link Kit will significantly alter your vehicle's handling characteristics. Be aware of the following:

• Improved Traction: Expect enhanced rear-wheel traction, especially during acceleration, due to better control of axle wrap and pinion angle.
• Enhanced Stability: The Panhard bar and 4-link design contribute to greater lateral stability, reducing body roll and improving cornering.
• Ride Quality: While performance-oriented, the urethane bushings can offer a balance between stiffness and ride comfort. However, the overall ride quality will depend on other suspension components (shocks, springs) and vehicle setup.
• Off-Road Use: If used in off-road applications, regularly inspect components for damage from impacts or excessive articulation.

Maintenance

Regular inspection and maintenance are crucial to ensure the longevity and safe operation of your maXpeedingrods Parallel 4 Link Kit.

• Visual Inspection: Periodically inspect all components for signs of wear, damage, rust, or loose fasteners. Pay close attention to welds, bushings, and rod ends.
• Fastener Torque Check: Re-torque all bolts and nuts to manufacturer specifications after the first 500 miles of driving, and then every 5,000-10,000 miles or during routine vehicle maintenance.
• Bushing Inspection: Check urethane bushings for cracking, deterioration, or excessive play. Replace worn bushings as needed to maintain proper suspension geometry.
• Cleaning: Keep the components clean from dirt, salt, and debris, especially if driving in harsh conditions, to prevent corrosion.
