The Core Shelf: Parts That Keep Trucks Moving

Brakes & Air System

  • Service & spring brake chambers (popular sizes and clamp styles)
  • Slack adjusters (manual & automatic), S-cam bushings, return springs
  • Brake shoes & pads, drums/rotors, hardware kits
  • Air lines, push-to-connect fittings, gladhands & seals
  • Air dryer cartridges (winter reliability starts here)

Brands to trust: Bendix (valves/ABS/air treatment), Meritor (brake hardware).

Filtration

  • Oil, fuel, and water-separator filters, primary/secondary air filters, and DEF filters
  • Cabin filters for HVAC performance and driver comfort

Wheel End

  • Hub oil seals & caps, unitized wheel bearings, spindle nuts & keepers
  • Grease/oil approved for wheel ends

Bearings & seals: Timken is the Tier-1 standard.

Suspension & Steering

  • Air springs (bags), shocks, torque rods & bushings, kingpin kits
  • U-joints and center support bearings for driveline vibration fixes

Electrical & Lighting

  • LED marker/stop/turn lamps, headlamps, pigtails, connectors, heat-shrink
  • Fuses, breakers, relays, flasher modules, battery cables, and cleaners
  • NOx, ABS, and wheel-speed sensors (common road-call culprits)

Belts & Hoses

  • Serpentine belts, tensioners/idlers, coolant & heater hoses, clamps, quick-couplers

Fluids & Shop Supplies

  • Engine oil & coolants (OEM-approved), DEF, gear oil, ATF
  • Brake cleaner, shop towels, anti-seize, dielectric grease, thread locker

Coupling & Body

  • Fifth-wheel rebuild kits, kingpin locks, mudflaps & brackets
  • Mirror assemblies, hood latches, door actuators (driver-reported issues you can solve fast)

Seasonal (Ohio)

  • Battery testers & replacement batteries
  • Fuel anti-gel, winter wiper blades, air line antifreeze
  • Extra air dryer cartridges ahead of the first freeze

OEM vs. Aftermarket: How to Decide

OEM (Original Equipment Manufacturer)

  • Best for: safety-critical components (air valves, brake friction, steering, suspension), complex electronics, items under warranty
  • Why: validated fit, consistent performance, current calibrations and updates

Aftermarket (Quality Tier-1/Tier-2)

  • Best for: filters, lighting, belts/hoses, hardware, cosmetic items
  • Why: cost advantage, wide availability—when sourced from reputable makers

Rule of thumb: If failure risks a red-tag (brakes, steering, ABS, wheel end), lean OEM or Tier-1. For routine consumables, vetted aftermarket is a smart way to lower cost per mile. Need a sanity check? Our counter team will cross-reference part numbers and share real-world failure data from fleets like yours.

New, Reman, or Used: What Makes Sense?

  • New: Highest reliability and warranty support—ideal for mission-critical systems.
  • Remanufactured: Strong value for starters/alternators, air compressors, calipers, power steering pumps, Eaton transmission components—backed by core credits and factory specs.
  • Used/Salvage: Reserve for body panels, interior trim, or non-safety hardware. Avoid used for brakes, airbags, bearings, and electronics that can strand a unit.

Quick Inspection Cues Your Techs Can Use

Brakes

  • Cracked/chunked linings, heat checks on drums/rotors, slow-to-release chambers
  • Excessive auto-slack travel or mismatched components across an axle

Suspension

  • Air bag dry-rot or audible leaks, oil-wet shocks, torn torque-rod bushings
  • Uneven tire wear → check alignment, bushings, and wheel bearings

Wheel End

  • Hub oil level drop, seal slinging, hot-to-the-touch hubs after a short run

Electrical

  • Intermittent lamps (corroded pigtails), green-crusted grounds, low system voltage under load

Filtration/Fluids

  • Restricted air filter (collapsed element), cloudy coolant, water in fuel bowl

Capture these checks during PMs and road-side calls; they map directly to your stocking list.

Set Pars That Match Reality (and Cut Carrying Costs)

  1. ABC your inventory.
    • A-items: fast movers (filters, lamps, brake chambers) → higher par, tight re-order point
    • B-items: moderate velocity (air springs, sensors) → mid par
    • C-items: slow, high-value (NOx sensors, ABS ECUs) → lower on-hand, vendor-stocked
  2. Standardize part numbers. Reduce SKUs across makes with cross-compatible components (our counter will verify fitment by VIN).
  3. FIFO everything. Especially filters, rubber, sensors—date code your shelves.
  4. Use core programs. Reman calipers, compressors, and alternators drop net cost—just keep a bin for cores and return weekly.
  5. Road-call kits. Pre-pack bins per model family with fuses/relays, lamps, pigtails, air fittings, DEF sensor, serp belt, coolant hose splice, clamps, fluids.

Brand Benchmarks That Don’t Let You Down

  • Meritor: brakes, axles, wheel-end components and hardware
  • Eaton: clutches, transmissions, transmission components
  • Bendix: air brake valves, dryers, ABS/ATC components
  • Timken: bearings, seals, and hub solutions

We stock these lines because they pass the only test that matters: fewer comebacks and fewer out-of-service events.

Fast Parts Delivery Across Ohio

When a truck is down, minutes matter. We offer:

  • Hot-shot delivery to shops and yards across Northern Ohio
