Bar's Leaks Axle and Differential Gear Repair
  • Seal Conditioner – stops current and prevents future leaks by protecting and reconditioning seals.
  • Extreme Pressure (EP) and Anti-Wear (AW) Agents – provide excellent metal-to-metal wear protection reducing noise and gear temperatures. Our sulfur, nitrogen and phosphorus additives meet the requirements of API GL-4 and GL-5 specifications.
  • Friction Modifier – supplements the EP/AW additives to help reduce noise and wear. This in turn helps shifting in a manual transmission and also stops chatter in limited-slip posi-traction axles.
  • Performance Additive Booster – includes tackifying agents and highly sheer-stable multigrade viscosity modifiers to keep oil on the gears and bearings where it can better lubricate, especially at higher temperatures. Pour Point Depressant (PPD) allows product to flow even at very low temps.
  • Manufactured in the USA, this product works in all manual gearboxes, differentials, open & posi axles and more. Stops pinion, axle, output shaft and other seal leaks. Reduces grinding, whining, clunking and protects gears.

Engine Armour - Engine, Transmission, Differential Reviver, Wear Reducer, and Mileage Booster - SAE Tested | Creates a Nano Ceramic Shield Coating over Internal Moving Parts (2oz - V4, V6 Passenger)
  • Engine Armour Tech is a SAE J1321 tested penetrating ceramic liquid metal sealing formula that has been well proven to reduce engine wear in tests by multiple independent laboratories and 10 years of successful track record in Canada and 12+ countries.  It clears away soot & carbon deposits and fuses into microscopic pores in meta as well as prevents the formation of sludge & abrasive carbon. Lubricants treat symptoms - We ATTACK the cause of soot & carbon damage.
  • It has been proven to SIGNIFICANTLY reduce soot build-up in DPF, turbo chargers and EGR valves as well as enhance engine performance - by promoting a more complete burn - thereby increasing torque, horsepower - reduced fuel consumption & emissions. We are not an oil additive but rather an inert liquid that WILL NOT mix with oil or change oil viscosity.  The effects of treatments extend PAST oil changes and can last as long as a year - depending on time and intensity of engine use.
  • Lab Reports consistently report SIGNIFICANT increases in torque, horsepower, fuel milage and reduced emissions.  Engine Armour Tech treatments not only deliver improvements in performance, but also reductions in operating costs and is proven to significantly reduce wear and increase the reliability and service life of equipment. When used in conjunction with traditional oil treatments, your machinery stand the best chance for long term reliability.
  • Engine Armour Tech ENHANCES Oil Performance by facilitating a more complete dispersion of engine oil on hot metal surfaces, providing more effective lubrication between moving metal components. INTERRUPTS the Soot & Carbon Cycle to reduce soot production by significantly reducing blow-by, increasing engine compression and boosting combustion efficacy, significantly reducing soot production in the combustion process and preventing harmful carbon deposits from forming in engines.
  • REDUCES Surface Friction: Engine Armour Tech penetrates into microscopic pores in metal and cleans away soot & carbon deposits. The heat activated formula fuses into metal cracks forming a durable glass-smooth ceramic shield that significantly reduces friction, heat, abrasion and wear.
