International Motor Sports Association's (IMSA) president Scott Atherton confirmed the race was part of the schedule for the 2018 IMSA SportsCar Championship (IMSA SCC) in August 2017.[1] It was the fifth consecutive year the event was held as part of the WeatherTech SportsCar Championship. The 2018 Sahlen's 6 Hours of the Glen was the sixth of twelve scheduled sports car races of 2018 by IMSA, and was the third round of the Patron North American Endurance Cup.[1] The race was held at the eleven-turn 3.450 mi (5.552 km) Watkins Glen International on July 1, 2018.[1]

After the Chevrolet Sports Car Classic 4 weeks earlier, Filipe Albuquerque and João Barbosa led the Prototype Drivers' Championship with 144 points, ahead of Eric Curran and Felipe Nasr who were tied with them on 144 points, and Hélio Castroneves and Ricky Taylor with 130 points.[2] With 121 points, the GTLM Drivers' Championship was led by Ryan Briscoe and Richard Westbrook with a seven-point advantage over Earl Bamber and Laurens Vanthoor.[2] In GTD, the Drivers' Championship was led by Bryan Sellers and Madison Snow with 125 points ahead of Katherine Legge with 122 points.[2]

IMSA released two separate technical bulletins regarding the Balance of Performance for the six-hour race. The first one was released on May 25, 2018, for the GT Le Mans (GTLM) class.[3] This was done to allow IMSA teams who were preparing for the 24 Hours of Le Mans in three weeks time, notably Corvette Racing and Chip Ganassi Racing, to have the beforehand knowledge of the Balance of Performance for the race so they could prepare better. In this Bulletin, the BMW M8 GTE received a reduction of turbo boost, as well as a 4-liter fuel capacity reduction. The second technical bulletin was released on June 21, 2018, which regarded the Balance of Performance in the Prototype (P) and GT Daytona (GTD) classes for the event.[4] In P, The Acura ARX-05 and Cadillac DPi-V.R received fuel capacity reductions of 2 liters. In GTD, Acura NSX GT3 received a 10 kilogram weight increase while the BMW M6 GT3 received a fuel capacity of reduction 2 liters.
