Driver-facing hardware

Mud flaps, mirror heads, wiper blades, and grab handles — items touched every shift and cited on walk-arounds.

Four cab-exterior parts are in the grid with card-level U.S. pricing.

Shop notes

Cab hardware is how drivers enter, see, and keep spray off the trailer doors. Mud flaps, west-coast mirror heads, HD wiper blades, and grab handles wear in plain sight and still get deferred until a roadside inspection.

Match bolt patterns and glass size on mirrors. Flaps tear at the weight pocket first — replace as pairs when one side is gone. Wiper length is not a guess; 28-inch HD blades that chatter need arm pressure checks, not just new rubber. Grab handles belong on locking hardware.

Most of these parts ship ground. Search RC30PPB or Velvac 715426 when you already have the stamp from the old unit.

Measure the cab you have

Mirrors, flaps, wipers, and grab handles look universal until the bolt pattern disagrees. Measure and match the cab you are standing beside.

Blade length and arm type decide wipe quality more than marketing claims on the box.

Mud flap size must clear duals and frame brackets at full steering lock.

Dry-fit mirrors and handles before final torque. Oval holes in cab skin need repair, not just longer bolts.
Replace oxidized clips and crushed nylon inserts during the same job.
After install, wash the cab and re-check fasteners — wash racks find loose hardware quickly.

Seasonal visibility

Seasonal wiper changes and post-winter mirror checks keep driver visibility legal and practical.

Keep removed blades and mirror heads until the driver signs off on a rain test.

Day cab and sleeper exteriors

Buyers-style flaps, Velvac-style mirrors, HD wiper blades, and grab handles here cover common Class 8 day cab and sleeper exteriors.

Each linked product page lists the make and model rows we publish for that hardware.

Hardware torque and orders

Cab sheet metal strips easily — use thread lockers and torque values from the body builder guide when available.

Ground shipping applies to most exterior hardware; see shipping policy and returns and refunds for timelines and opened-box rules.

Crosses without guessing

Hardware crosses help; hole spacing and arm geometry still decide the order.

HEAVY TRUCK PARTS, INC. sells cab accessories as an independent retailer — names on this page are compatibility labels.

Cab exterior SKU notes

SKU notes only; dollar amounts stay on the grid cards.

Buyers RC30PPB is a 24 by 30 inch black polymer mud flap pair for tractors and trailers — specs on Buyers 24x30 Polymer Mud Flaps Pair.

Velvac 715426 is a 2020-style west coast door mirror head for 102-inch Class 8 bodies — mount details on Velvac 2020 West Coast Mirror Head.

Clix 28HD sells 28-inch heavy-duty windshield wiper blades as a pair — fit your arms via Clix 28 in Heavy-Duty Wiper Blade Pair.

United Pacific 10960 is a chrome-plated cab grab handle set for entry and sleeper access — order on United Pacific Chrome Cab Grab Handle Set.

These four listings are the Cab and Exterior department on this site.

Drivers notice mirrors and wipers every shift. Fogged glass and streaking blades create avoidable near-misses.

Grab handles and steps are fall-protection hardware. Treat cracked mounts as a safety defect, not a cosmetic note.

Flaps that tear off become road debris. Check bolts after the first wash and after winter ice builds on the brackets.

Mirror glass and arm tension

Velvac 715426 heads mount on west-coast doors with specific arm geometry — swapping only the glass when the arm is bent repeats vibration on the highway.

RC30PPB flaps hang from brackets that must survive car-wash brushes; use lock washers or nylon locking nuts where the body builder manual allows.

Driver safety touches

United Pacific 10960 grab handles see full body weight on icy steps. Replace handles with cracked welds before a slip injury, not after an insurance call.

Clix 28HD blades need clean glass and straight arms — treating chatter with only new rubber when the arm is bent wastes another pair by Friday.

Exterior hardware orders ship from HEAVY TRUCK PARTS, INC. in Miami; confirm length and width on RC30PPB flaps when dual tires are newly installed.

Winter prep often pairs Clix 28HD blades with mirror glass cleaning — schedule both before salt season so drivers are not scraping ice with worn rubber.

Grab handle sets like 10960 should be torque-checked after the first dozen entries; cab vibration loosens hardware faster than office furniture specs suggest.

Velvac 715426 mirror orders should note whether you need passenger, driver, or both — west-coast mounts differ by door hinge side even when the stamp matches.

Buyers RC30PPB mud flaps ship as pairs — replace both sides when road spray asymmetry already ate one flap to the weight line.
