Torque Poly Fender Mounting Bracket Kit Black — 30.5" Arms, 5" Offset, Bolt-On

TORQUE Poly Fender Mounting Bracket Kit Black is a ready-to-install pair of polymer mounting arms and hardware engineered to secure dual rear-wheel polyethylene fenders on semi trucks and work trucks.

Designed as a direct, durable replacement for part numbers like 8591000, 8590195, and 8590245, this kit provides two 30.5" mounting arms with a 5" offset to clear spring shackles and adapt mounting height. The set includes frame bolts, hanger brackets, and all necessary fasteners so you can mount polyethylene quarter fenders to 19.5"–24.5" dual rear-wheel setups without fabricating custom parts.

How will this kit fit my truck or trailer?

The TORQUE bracket kit is made for universal dual-rear-wheel applications and works with a wide range of truck and trailer models. It accepts tires from 19.5" to 24.5" and is commonly used on dump trucks, garbage trucks, work trucks, and utility vehicles.

• 30.5" arm length with 5" offset for shackle clearance.
• Adjustable mounting height to match various frame rails.
• Compatible with common polyethylene quarter fenders.
• Fits dual rear wheel configurations without modification.

What hardware and parts come in the box?

Each kit contains two completed mounting assemblies and a full set of fasteners so you won’t need additional parts for a standard installation. The included hanger brackets and frame bolts are sized to secure the mounts and fenders to typical heavy-duty truck frames.

• Two polymer mounting arms (30.5" length).
• Hanger brackets and frame bolts included.
• All nuts, washers, and bolts required for assembly.
• Instructions for basic bolt-on installation.

How durable is the TORQUE polymer design in real-world conditions?

The brackets are molded from an impact-resistant polymer engineered to resist chips, dents, and corrosion that metal parts often suffer. That makes them lighter than steel and less prone to rust, while still providing dependable support for polyethylene fenders under typical road and worksite conditions.

• Impact-resistant polymer construction for toughness and weight savings.
• Natural corrosion resistance — no rust like steel.
• Designed to tolerate road debris and regular use.
• Backed by a 1-year, unlimited-mileage warranty for manufacturing issues.

Will installation require welding or special tools?

No welding is required for standard installations; the kit is intended to bolt to existing frame rails and hanger points. Basic mechanic tools — sockets, wrenches, and a torque wrench — are typically sufficient, and the adjustable mounting height simplifies alignment with the fender.

• Bolt-on installation — no welding needed for most frames.
• Requires common hand tools (sockets, wrenches, torque wrench).
• Adjustable brackets make alignment quicker and easier.
• Includes fasteners to avoid sourcing additional hardware.

Who is this for: The TORQUE Poly Fender Mounting Bracket Kit Black is aimed at fleet managers, diesel mechanics, and owner-operators who need a reliable, corrosion-resistant mounting solution for polyethylene quarter fenders on dual rear-wheel heavy trucks. It's ideal when replacing damaged mounts, upgrading worn metal brackets, or fitting new poly fenders without fabrication. If you run dump trucks, garbage trucks, service trucks, or trailers with 19.5"–24.5" dual tires and want a bolt-on, durable mounting option, this kit is built to match those needs while keeping installation straightforward.
