In short, yes. "America First" was a common slogan for the KKK and for white supremacists dating back at least to the 1920s.

Here's an image of women in the Klan marching in the 20s during their resurgence bearing a sign with the 'America First' slogan

And here's a commemorative coin dated to the "Third Movement" (1954-1969) bearing the slogans - The Invisible Empire, America First, and Preserve Racial Purity..

The coin is discussed by D.E. Birdsell in his 1977 book, Ku Klux Klan Tokens and he mentions that he was unable to find them being officially made by the Klan as an organization, but it was undoubtedly made by an individual adherent to the group. The phrase "America First" is very deeply ingrained into the KKK's ideology, as are many other phrases meant to be generally agreeable to the population that have dark undertones.

A 1921 congressional hearing about the Klan's activities also has them directly stating "[The Klan] stands for America first — first in thought, first in affections, and first in the galaxy of nations. The Stars and Stripes forever above all other and every kind of government in the whole world."

The idea of returning America to a mythical past is also integral to the Klan starting in the second movement. Many far-right movements have it as their designated goal, Hitler writes about the end result of Nazism being a return of the superior germanic people to their agrarian and peaceful past without the corruption of inferior and insidious others. The Klan, starting in the '20s were highly focused on spreading this growing idea of the antebellum South as a paradise that has since been corrupted by the aftermath of the Civil War and the black population entering spaces they hadn't been before. The Birth of a Nation was a film highlighting the loss of the peaceful South to a violent and savage black population, only for the people to be saved by the heroic KKK, this was right at the beginning of the Second Movement and set the tone for their messaging. Overall, their message was successful and the idea of the idyllic antebellum South was very prominent in American culture for a very long time. I don't know of any specific examples of the Klan pushing the exact message of "Make America Great Again", but they've certainly pushed messaging that might be worded differently but is essentially the same in spirit.
