Hino 238-338 Truck Frame & Chassis

Frequently Asked Questions About Hino 238-338 Truck Frame & Chassis

What years and models are compatible with these frame and chassis parts?

Our Hino 238-338 frame and chassis parts are designed to fit Hino 238, 258, 268, and 338 series trucks from model years 2005 through 2024. The 238/258 models share the same frame dimensions, while the 268/338 models have a wider frame rail spacing. Always verify your specific truck's VIN and model year before ordering, as Hino made minor frame updates in 2011 and 2017 that may affect certain mounting points.

What are the most common installation challenges for aftermarket bumpers on these trucks?

The most frequent installation issues involve the front bumper mounting brackets, which may require drilling new holes if upgrading from OEM plastic to steel aftermarket bumpers. Many customers report needing to relocate fog light wiring harnesses and air horn lines. For 2011 and newer models, the frame rail ends have pre-drilled mounting holes that may not align with some universal aftermarket bumpers. We recommend having 2-3 hours available for installation and basic hand tools plus a drill with metal bits.

What material options and finishes are available for replacement bumpers?

Most aftermarket bumpers for Hino 238-338 trucks come in 14-gauge steel with either chrome plating, polished stainless steel, or powder-coated finishes. Chrome options typically feature triple-chrome plating for durability, while powder-coated versions are available in black, white, or custom colors. Stainless steel bumpers offer the best corrosion resistance but are generally 30-40% more expensive than chrome-plated steel options.

Will aftermarket frame and chassis parts affect my truck's warranty?

Installing aftermarket bumpers, steps, or other frame-mounted accessories typically will not void your Hino warranty, as these are considered appearance modifications. However, any frame drilling or welding could potentially affect frame-related warranty claims. We recommend checking with your dealer before making structural modifications. Most bolt-on accessories that use existing mounting points pose no warranty concerns.

What weight capacity should I expect for aftermarket steps and running boards?

Quality aftermarket steps for Hino 238-338 trucks are typically rated for 500-600 pounds per step. Heavy-duty commercial-grade options can support up to 750 pounds. The frame mounting brackets are the critical component - ensure they're made from at least 3/16-inch steel plate. Avoid universal fit steps that use U-bolt clamps, as these can loosen over time. Look for model-specific brackets that bolt directly to the frame using existing holes or frame pockets.
