Overview of 555 Suspension Parts
555 (often stylized as "555" or "555" with a logo) is a brand under the Japanese company JTEKT, which also manufactures Koyo bearings. The brand specializes in steering and suspension components for both domestic and import vehicles. Their product line includes ball joints, tie rod ends, sway bar links, control arms, and related hardware. Many 555 parts are designed to meet or exceed original equipment (OE) specifications, making them a popular choice for replacement and restoration.
Key Features and Quality
Materials and Construction
555 suspension parts are typically constructed from forged steel or high-strength alloys. Ball joints and tie rod ends use hardened steel studs and sintered metal bearings for durability. Many components feature rubber or polyurethane boots filled with grease to protect against contaminants. The brand emphasizes corrosion resistance, often applying zinc plating or other coatings to exposed metal surfaces.
Fitment and Compatibility
One of the strongest points of 555 is its precise fitment. Parts are manufactured to match original dimensions, which simplifies installation. For common applications like Toyota, Honda, Nissan, and Mazda, 555 often offers direct bolt-on replacements. However, some parts may require minor adjustments, so always verify compatibility with your specific vehicle model and year.
Quality Control
555 maintains strict quality control standards, with each part inspected before leaving the factory. This reduces the likelihood of defects, but occasional issues arise – typically related to boot tearing or premature wear in extreme conditions.
Popular 555 Suspension Components
Ball Joints
555 ball joints are widely used for front and rear suspensions. They are available for both upper and lower positions, with options for pressed-in or bolt-on designs. The studs are typically heat-treated for strength, and the socket is designed to reduce friction and play.
Tie Rod Ends
Tie rod ends from 555 are known for their tight tolerances and long service life. They include left and right threads for easy adjustment, and the outer tie rods often come with a cotter pin slot. Many users report that 555 tie rods match the feel of factory parts.
Control Arms
555 offers control arms for both front and rear suspensions. These are usually sold as complete assemblies with ball joints and bushings pre-installed. The bushings are made of rubber or urethane, depending on the application. Control arms are a cost-effective way to replace multiple worn components at once.
Sway Bar Links
Sway bar links from 555 are straightforward to install and come with new nuts and bolts. They are available for both front and rear stabilizer bars. The links are often made of steel with urethane bushings for reduced noise and vibration.
Pros and Cons of 555 Suspension Parts
Pros
- Affordable Price: Compared to OEM parts, 555 offers significant savings without a major sacrifice in quality.
- Good Availability: Parts are widely stocked at auto parts stores and online retailers.
- Reliable Performance: For daily driving and mild performance use, 555 components provide a solid balance of comfort and durability.
- OEM Fitment: Parts are designed to match factory specifications, making installation easy for DIYers.
Cons
- Variability in Quality: Some users report that certain batches have softer rubber boots that crack sooner.
- Not for Extreme Use: Off-road or track applications may exceed the design limits of 555 parts – consider higher-end brands for heavy use.
- Limited Warranty: The warranty is typically shorter than premium brands like Moog or AC Delco.
How to Choose the Right 555 Suspension Parts
When selecting 555 parts, start by identifying the exact components your vehicle needs. Common signs of wear include clunking noises, uneven tire wear, and loose steering. Use your vehicle's VIN or look up parts by make, model, and year. If you're unsure, consult a mechanic or a parts specialist.
Consider the driving conditions. For daily commutes and light hauling, 555 is a great choice. If you frequently drive on rough roads or carry heavy loads, you might want to upgrade to heavy-duty variants or another brand. Also, check if the part includes all necessary hardware – some 555 tie rod ends come with castle nuts and cotter pins, while others may need to be purchased separately.
Comparison with Other Brands
555 vs. Moog
Moog is known for its problem-solving designs, such as greaseable ball joints with a unique socket design. Moog parts are generally more expensive but offer longer service life and better warranty support. 555 is a more budget-friendly alternative, with comparable performance for daily driving.
555 vs. OEM
OEM parts guarantee exact fit and are often the safest choice, but they cost more. 555 replicates OEM specs closely and is a popular choice for cost-conscious owners. For older vehicles where OEM parts are discontinued, 555 is a reliable substitute.
555 vs. Beck/Arnley
Beck/Arnley is another aftermarket brand that focuses on OE-quality parts. Both brands offer similar levels of quality and pricing. Beck/Arnley may have a broader range for European cars, while 555 is stronger for Japanese applications.
Installation Tips
- Always inspect the new part before installing: check the boot for tears, confirm the stud movement is smooth, and verify the threads are clean.
- When installing ball joints or control arms, use a press if needed and never hammer directly on the threaded stud.
- After installation, get a wheel alignment to prevent premature tire wear. This is essential whenever you replace steering or suspension components.
- Follow torque specifications for all fasteners. Over-tightening can damage the part or compromise safety.
Final Recommendation
For most drivers, 555 suspension parts offer an excellent balance of quality and value. They are particularly well-suited for Japanese vehicles and for those who need reliable replacements without breaking the bank. If you drive a compact car, sedan, or light SUV primarily on paved roads, 555 components will serve you well. However, if you push your vehicle hard or require maximum durability, consider stepping up to a premium brand like Moog or OEM. Always source parts from reputable suppliers to avoid counterfeits. With proper installation and routine maintenance, 555 suspension parts can restore your vehicle's ride quality and handling for many thousands of miles.
