DRUM/TOTE CHARGE - $50.00 per Drum/$250.00 per Tote, refundable when returned in original condition

Premium Canadian-made BOSS GL-5 gear oils – choose full synthetic grades (75W-90 and 75W-140) for superior flowability, minimized gear wear, reduced frictional drag, and protection against heavy loading failures in extreme weather, or the conventional 80W-90 for outstanding thermal stability, corrosion/rust protection, and superior seal compatibility in standard applications. All grades are formulated with high-quality base stocks and sulfur-phosphorus extreme pressure (EP) additives to deliver exceptional anti-wear, anti-scuffing, and anti-pitting performance in hypoid differentials, limited-slip units, manual transmissions (non-synchronized), rear axles, and final drives under high-shock, high-torque, and severe-service conditions – perfect for automotive, truck, off-road, and industrial gear systems in harsh Canadian climates.

Provide reliable protection against thermal breakdown, oxidation, foam, and deposits while ensuring smooth operation, extended component life, and compatibility with limited-slip additives.

✅ Key Benefits:

  • Extreme pressure (EP) additives protect against scuffing, scoring, pitting, and heavy shock loads
  • Outstanding thermal and oxidation stability – resists thickening and sludge formation
  • Superior rust, corrosion, and foam inhibition
  • Excellent seal compatibility to prevent leaks and extend seal life
  • Limited slip capable – suitable for LSD differentials without additional modifiers
  • Superior low-temperature fluidity (synthetics) for cold-weather performance
  • Ensures top-notch field performance in extreme hot/cold conditions
  • Proudly formulated and bottled in Canada

✅ Grade-Specific Advantages:

  • 75W-90 Synthetic → All-season versatility with excellent cold-flow (-51°C pour) and reduced drag – ideal for passenger vehicles, light trucks, 4x4s, and trailers in variable climates.
  • 75W-140 Synthetic → Thicker film strength for extreme heavy-duty, high-heat, and towing applications – maximum protection in racing, off-road, and severe service.
  • 80W-90 Conventional → Reliable value-priced option for standard differentials and transmissions – proven in automotive, truck, and rear axle applications requiring GL-5.

Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.

Our pup loves the cronch cronch!
Style: Ball, Size: Medium (Pack of 1)
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing. He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.
