Nissan 1400 Suspension Parts for Sale – Complete Buyer's Guide

The suspension system of the Nissan 1400 (also known as the Datsun 1400 in some markets) plays a critical role in ride comfort, handling, and safety. Whether you're restoring a classic or upgrading for performance, finding the right suspension parts for sale is essential. This guide covers the key components to consider, what to look for in quality, and how to make a smart purchase for your Nissan 1400.

Understanding Nissan 1400 Suspension System

The Nissan 1400 uses a front independent suspension with torsion bars and a rear solid axle with leaf springs. This setup is simple, durable, and common among light trucks of its era. The torsion bars are adjustable for ride height, while the rear leaf springs support the load. Over time, bushings, shocks, and springs wear out, leading to poor ride quality and uneven tire wear. Knowing the layout helps you identify which parts need replacement.

Common Suspension Parts for Nissan 1400

Shock Absorbers

Shock absorbers control the oscillation of springs. For the Nissan 1400, you'll find standard gas shocks for daily driving and heavy-duty options for carrying loads. Look for brands like Monroe, KYB, or Bilstein (depending on availability). Ensure the shock length and mounting style match your model year. Twin-tube shocks work well for general use, while monotube shocks offer better heat dissipation for off-road or heavy use.

Coil Springs and Torsion Bars

The front suspension relies on torsion bars, not coil springs. Torsion bars are long steel bars that twist to absorb bumps. If your Nissan 1400 sits low or sags, the torsion bars may need adjustment or replacement. Aftermarket torsion bars are available from companies like Sway-A-Way or custom spring shops. For the rear, leaf springs are the norm. Do not confuse coil springs—this model typically does not use them unless modified.

Leaf Springs

Rear leaf springs support the truck bed's weight. Over time, they lose arch and may crack. When shopping for leaf springs, consider the load rating: standard for daily use, or heavy-duty for towing or hauling. New leaf springs will restore ride height and stability. Some sellers offer progressive leaf packs for a smoother ride under varying loads.

Bushings and Ball Joints

Rubber bushings and ball joints wear out, causing clunks and loose steering. Polyurethane bushings are a popular upgrade—they are stiffer and longer-lasting than rubber. However, they transmit more road noise. Ball joints should be replaced in pairs. Check for grease fittings; some aftermarket parts are sealed, but greasable units allow regular maintenance.

Sway Bars

The Nissan 1400 does not always come with a rear sway bar. Adding one or upgrading the front sway bar can reduce body roll. Aftermarket sway bars are thicker and may be adjustable. Pair them with reinforced links and bushings for best results.

Factors to Consider When Buying Suspension Parts

OEM vs. Aftermarket Quality

Original Equipment Manufacturer (OEM) parts are made by the same supplier as the factory, ensuring exact fitment. Aftermarket parts vary widely—some match OEM quality, others may be subpar. Look for reputable brands with a history of making parts for this model. Avoid no-name parts from unknown sources.

Material and Durability

For leaf springs, measure the spring rate (lbs per inch). For bushings, polyurethane is harder but lasts longer. Shocks should have a corrosion-resistant finish. Check if torsion bars are made of spring steel. Higher quality materials usually cost more but perform better.

Fitment and Compatibility

The Nissan 1400 was produced from the late 1970s to the mid-2000s. Parts for different years may vary. Always verify with the seller if the part fits your specific model year. Some aftermarket parts are universal and may require modification. Ask for vehicle-specific listings.

Price and Value

Suspension parts for the Nissan 1400 are generally affordable. A set of four shocks can cost $80–$200. Leaf springs run $100–$300 each. Bushings kits are $30–$100. Don't skimp on ball joints or tie rod ends, as failure can cause accidents. Compare prices from multiple suppliers, but prioritize component quality over low price.

Tips for Replacing Suspension Parts

• Always replace parts in pairs (both front shocks, both rear leaf springs, etc.) for balanced handling.
• Use safety stands; never rely on a jack alone.
• After installing new springs or torsion bars, get a professional alignment.
• When replacing bushings, lubricate properly to prevent squeaks.
• Torque all fasteners to specifications; too loose or too tight can cause failure.

Final Recommendation – Choosing the Right Parts for Your Needs

For a daily driver Nissan 1400, stick with OEM or quality aftermarket parts that match the original specifications. KYB shocks, standard leaf springs, and rubber bushings will give you a comfortable ride. If you use the truck for hauling or light off-roading, upgrade to heavy-duty leaf springs, polyurethane bushings, and a front sway bar. For restored show trucks, consider adjustable torsion bars and gas shocks for a smooth stance. Before buying, measure your existing parts and confirm fitment with the seller. With the right parts, your Nissan 1400 will ride like new again.
