About Mopar

Combine the first syllables of the words “motor” and “parts” and you get Mopar.

Given the reputation this brand has garnered over the years, it’s easy to see why their name has become somewhat synonymous with quality auto parts.

Founded in 1937, Mopar represents a division of the former Chrysler Corporation.

Stellantis, a Netherlands-based automobile manufacturer, currently owns Mopar.

Before the brand started to manufacture a variety of automotive components, the name Mopar was first featured on a can of antifreeze made by Chrysler.

After coming to the realization that the name was easy to remember, Chrysler started using it on other products.

Today, Mopar is a brand that makes a range of auto parts and equipment for vehicles manufactured by Fiat, Chrysler, Dodge, Jeep, and Ram.

The components they’re best known for include brakes, timing belts, filters, wiper blades, batteries, and shock absorbers.

Aside from having a very strong presence in the automotive aftermarket, Mopar also has a reputation for building a limited number of custom cars.

For instance, when the brand celebrated its 80th anniversary in 2017, it released a line of special edition Dodge Challenger vehicles. A total of 160 Mopar 2017 Dodge Challengers were made.

Mopar has a global reach that spans more than 150 markets. As a notable service provider in the automotive industry, the company has over 1,750 Mopar Express Lanes in 20 different countries.

Mopar Express Lanes are excellent options for quick oil changes and vehicle checkups with no required appointments. Check out all the Mopar parts that we carry for your Dodge or Jeep.
