SHINJEW Quarter Fender Pair for Semi Trucks 24x24 Black HDPE Heavy-Duty with Hardware

These SHINJEW black poly quarter fenders are a 24" x 24" heavy-duty HDPE pair designed to protect semi trucks (Freightliner, Kenworth, Peterbilt and similar) and include standard mounting hardware.

Built from thick high-density polyethylene, this quarter fender set delivers weather-resistant coverage and impact resilience for tractor units and heavy trailers. The kit ships as a matched pair with mounting hardware so you can replace worn or cracked fenders quickly and get back on the road with dependable splash and debris protection.

How will these fenders hold up against road debris and weather?

SHINJEW fenders use super-tough HDPE that resists cracking, splitting and deformation in cold, heat and wet conditions. The material flexes to absorb minor impacts rather than shatter, and the smooth black finish sheds road grime for easier cleaning.

• HDPE construction for impact resistance and flexibility
• UV-stable black finish to reduce fading and surface chalking
• Non-porous surface for quick wash-downs
• Designed to resist crushing under typical roadside contact

Will these quarter fenders fit my Freightliner, Kenworth, or Peterbilt?

The pair measures 24" x 24" and is engineered for common semi truck configurations used by Freightliner, Kenworth and Peterbilt models. They are quarter-fender style, suitable for many sleeper and day cab wheel openings, but you should verify wheel well dimensions before ordering.

• Nominal size: 24 inches by 24 inches per fender
• Quarter-fender design for common semi truck wheel arches
• Standard mounting hardware included for typical bolt-on installations
• Check vehicle wheel well clearance and bolt pattern prior to install

How easy is the installation and what comes in the package?

Installation is straightforward for a technician with basic tools: the set includes two fenders and a standard hardware pack, allowing bolt-on replacement of existing quarter fenders. Pre-drilled or marked mounting points simplify alignment; minor trimming is rarely required when fitment is confirmed.

• Included: two 24" x 24" quarter fenders (one pair)
• Included: standard mounting hardware for typical installations
• Requires common shop tools—wrenches, drill and fasteners as needed
• Local mounting variations may need minor adjustments or adapters

How do these fenders perform over time and how should I maintain them?

The HDPE material resists long-term degradation from salt, oils and UV exposure, giving you extended service life compared with thin plastics. Routine rinsing and occasional mild detergent cleaning keeps the finish intact and minimizes abrasive wear from accumulated grit.

• Periodic wash with water and mild soap removes road salts and grime
• Inspect mounting points regularly for corrosion or loosened fasteners
• Replace if deep cuts or structural damage compromise protection
• UV-resistant composition reduces need for protective coatings

Who is this for: drivers, fleet managers and maintenance shops that need a durable, ready-to-install quarter fender solution for Freightliner, Kenworth, Peterbilt and similar semi trucks. If you want a rugged, low-maintenance mud flap/fender pair that withstands heavy duty use and includes the mounting hardware to speed installation, this SHINJEW kit is made for replacing worn OEM or aftermarket quarter fenders while keeping downtime minimal.
