What is included in the package and what materials are used?

This shipment contains all parts needed to replace both upper and lower ball joints on one vehicle's front end. Components are manufactured from quality iron for strength, with rubber seals to protect moving surfaces from dirt and moisture.

• 4 ball joints (upper and lower set)
• 4 lock nuts, 4 split pins, and 4 circlips for secure installation
• Ball joint body dimensions approximately 66 × 32 mm for direct OEM match
• Iron construction with rubber seals to extend service life under off-road use

How do these ball joints improve handling and maintenance?

Replacing worn ball joints removes play in the front suspension, which tightens steering response and reduces uneven tire wear. Using parts that align with original equipment dimensions ensures straightforward installation and predictable handling after service.

• Removes steering looseness caused by worn pivots
• Restores correct wheel alignment geometry when fitted properly
• Includes hardware to complete the swap without sourcing extra parts

Are these ball joints easy to install and what should I prepare?

Installation is typical for front-end suspension work and requires common tools and safety precautions. If you have mechanical experience, you can perform the replacement at home; otherwise a mechanic or ATV shop can complete the job quickly using standard presses or pullers if needed.

• Prepare a jack and stands, basic hand tools, and a ball-joint press or removal tools
• Torque nuts to OEM specifications and use supplied split pins and circlips for safety
• Inspect control arms and bearings while the joints are removed for complete service
