Fender Weight Comparison by Material

When you’re looking to add protection to your truck, you want something that’s heavy duty. A product that can withstand the rough conditions often faced by trucks on and off the road. As you’ll see below, one of the main benefits of poly fenders is achieving ‘heavy duty status’ without actually being heavy.

The process of ‘lightweighting’ or reducing the total amount of truck weight has many cost-saving benefits. Find out more about the benefits of weight reduction on trucks from the NACFE.

  • A 0.5-0.6% increase in fuel economy for every 1,000 lbs reduction

  • Every pound of weight saved makes room for additional freight

  • Weight reduction allows for increased driver comfort amenities

Style of Fenders Poly (Robmar) Aluminum (0.125″) Fiberglass Stainless Steel (14 ga)
Single Axle (All 4 drives) 50 lbs 96 lbs 115 lbs 180 lbs
Full Tandem (All 4 drives) 48 lbs 85 lbs 95 lbs 160 lbs

The table above uses our single axle fender model SAF-225 and our full tandem fender model FTF-27 as a reference point when comparing to other fender manufacturers using their similar models. The weights above are not exact. They represent the best possible average of available options on the market. The weights above refer to the fenders only and not mounting hardware.

Fender Price Comparison by Material

Depending on the type of material used and the manufacturer, you could be paying anywhere between $300 and $3000 for your next fender system (plus mounting hardware). Every build material has its advantages but cost remains a primary concern for anyone in the market for new fenders.

Style of Fenders Robmar Poly Industry Leader Poly Aluminum (0.125″) Stainless Steel (14 ga) Fiberglass
Single Axle (All 4 Drives) $300 $940 $600-$,1000 $900 $1,200-$1,800
Full Tandem (All 4 Drives) $300 $800 $700-$900 $890 $1,200-$3,000

Poly fenders are an obvious choice for any driver or fleet manager that’s looking to protect their equipment while saving money. Another aspect that factors into the overall cost of fender ownership is repairs. Thermoformed plastic can take a lot of hits and scuffs that would send fiberglass or metal straight to the shop. Not to mention the fact that totally replacing our plastic systems is often cheaper than the repair costs alone for other material types.

No matter what type of material you end up choosing, make sure to drive safe out there!
