KEMSO OEM Replace Fuel Pump For Suzuki King Quad 400
The KEMSO OEM fuel pump is designed to restore or upgrade fuel delivery for several Suzuki King Quad and related 450-class platforms (LT-A400F and similar models). With support for up to 200 LPH, the unit offers significantly higher flow than older factory pumps, which can help maintain stable engine performance under load and high-RPM operation. The pump package emphasizes compatibility with gasoline and ethanol blends, making it a practical choice for riders who rely on premium-grade fuels or mixed gasoline in remote riding environments. USA-based technician support is noted for post-purchase assistance.
OEM Replace Intank Fuel Pump For Suzuki King Quad 400
This in-tank pump replacement focuses on restoring the original fuel delivery characteristics for Suzuki King Quad 400-era machines and related 450-class quads. It supports consistent fuel flow under acceleration and high-load conditions, reducing the risk of vapor lock and fuel starvation during aggressive riding. As with many OEM-style pumps, installation is straightforward for technicians familiar with ATV fuel systems. This option is particularly suitable for riders who prefer a direct compatibility fit with their stock fuel assembly.
Maxauto ATV Sport Quad Tires 20×10-9 (Set of 2)
These rear tires in 20×10-9 size are designed for sport quads running on 9-inch rims. The tubeless design and robust tread provide reliable grip on dirt, gravel, and mixed terrain commonly encountered by 450-class riders. The tire specifications emphasize compatibility with a range of popular ATV models, and riders should confirm the 8-inch rim width compatibility before purchasing. The set of two tires helps refresh rear traction, which is critical for acceleration, braking, and cornering at higher speeds on dirt tracks and trails.
MASSFX Rear Tire Set (2x) 20X10-9 4ply
The MASSFX rear tire set is built with 4-ply construction designed to withstand rugged riding. The 20×10-9 sizing targets larger-quart popular sport quads, with tread patterns intended to offer improved braking control and traction across mixed surfaces. As with other aftermarket tires, fitment should be verified against your quad’s rim width and overall clearance to avoid rubbing or clearance issues at full steering lock or suspension travel.
tianfeng Rear Brake Caliper For Suzuki Quad
The tianfeng brake caliper provides an affordable replacement option for Suzuki Quadsport riders, covering models from the late 1980s through 2014 as applicable. The package includes essential components such as a parking brake block plate, banjo bolt, and brake pads but does not include a mounting bracket. It’s suitable for riders seeking a straightforward caliper upgrade to restore braking performance on rear brakes, contributing to safer stoppage during high-speed riding and technical terrain navigation.
Buying Guide: Key Purchase Considerations For 450 Sport Quads
- Intended use and compatibility: Match parts to your quad’s model year, engine displacement, and braking or fueling system configuration. Verify OEM or aftermarket compatibility with your specific 450-class model.
- Fuel system upgrades: For high-load riding, consider pumps with higher flow capacity to maintain stable engine performance. Ensure ethanol compatibility if you regularly use ethanol-blended fuels.
- Tire performance and sizing: Choose tires based on terrain (dirt, mud, or mixed surfaces) and ensure rim compatibility. Consider tubeless designs for ease of maintenance and puncture resistance.
- Braking components: Inspect calipers, rotors, and lines for wear. Replacements should come with necessary mounting hardware and be suited to your braking system type.
- Battery and electrical reliability: A high-cranking CCA battery can improve cold-start performance on a 450-class engine, especially in cool climates or during long rides.
- Installation considerations: Some parts require professional installation or specialized tools. Review warranty terms and return policies if purchasing aftermarket parts.
- Maintenance interval planning: Align upgrades with scheduled maintenance to maximize longevity and prevent downtime during riding seasons.
- Cost vs. benefit: Weigh the performance gains against price, warranty support, and availability of replacement parts or technicians in your area.
- Safety and compliance: Ensure any braking or fuel system modifications comply with local regulations and rider safety standards.
These considerations help riders evaluate trade-offs between performance, durability, and cost across a range of 450 sport quad configurations. By selecting components that fit your model and riding style, you can enhance reliability, handling, and overall enjoyment on trails and tracks.
