Kansas Speedway, the track where the race was held.

Kansas Speedway is a 1.5-mile (2.4 km) tri-oval race track in Kansas City, Kansas. It was built in 2001 and it currently hosts two annual NASCAR race weekends. The Verizon IndyCar Series also raced at here until 2011. The speedway is owned and operated by the International Speedway Corporation.

Kevin Harvick entered Kansas with a 40-point lead over Martin Truex Jr. after a fourth-place finish at Talladega. Jimmie Johnson entered 52 back following a runner-up finish the week before at Talladega. Joey Logano entered 59 back. Dale Earnhardt Jr. entered 75 back after winning the previous week at Talladega.

The entry list for the SpongeBob SquarePants 400 was released on Monday, May 4 at 2:52 p.m. Eastern time. Forty-four cars were entered for the race. Erik Jones, who drove in relief of Denny Hamlin at the 2015 Food City 500 at Bristol Motor Speedway, made his official Sprint Cup Series debut in the No. 18 Joe Gibbs Racing Toyota. Joey Gase returned to the No. 32 Go FAS Racing Ford after Bobby Labonte drove it the previous race at Talladega Superspeedway. Ty Dillon made his first Cup start since the 2015 Daytona 500 in the No. 33 Hillman-Circle Sport LLC Chevrolet. Brett Moffitt returned to the No. 34 Front Row Motorsports Ford that he drove in Las Vegas and Phoenix. David Ragan moved to the No. 55 Michael Waltrip Racing Toyota after driving the No. 18 Toyota the last nine races.

Kevin Harvick was the fastest in the first practice session with a time of 28.306 and a speed of 190.772 mph (307.018 km/h).[12]

Erik Jones, making his official Sprint Cup Series debut, was the fastest in the final practice session with a time of 28.227 and a speed of 191.306 mph (307.877 km/h).[13] “There’s been a lot of people that have been involved over the past few weeks to get me ready for this,” Jones told Fox Sports 1. “I think a lot of it was preparing mentally, watching videos, watching tape, talking to Kyle (Busch) and my teammates and just trying to get the best information I could out of everybody. It’s pretty cool to be fastest in practice. I know it’s only practice, but it’s still pretty cool. … There’s a lot of great race car drivers. It’s just really an honor to be fastest this practice.”[13]

The race was scheduled to start at 7:46 p.m., but the threat of weather moved the start time up to 7:36. The race started at 7:39 when Joey Logano led the field to the green flag. Going into turn 3, Jimmie Johnson got loose and about took out teammate Dale Earnhardt Jr. He was saved by the first caution of the race flew on lap eight for a two car wreck on the backstretch and turn 4. Exiting turn 2, Jeb Burton had a left-front flat and spun out on the backstretch, however at that point the race stayed green. Teammate J. J. Yeley spun and made contact with the wall in turn 4, which caused the caution.[15]

The race restarted on lap 13. Alex Bowman dropped to the apron on the front stretch for electrical issues that dropped him to 42nd. The second caution of the race flew on lap 26. This was a scheduled competition caution. Most of the leaders took just two tires on this stop.[15]

The race restarted on lap 30. Kurt Busch went ahead of Logano in turn 3 and took the lead on lap 31. Teammate Kevin Harvick passed him in turn 1 to take the lead on lap 51. Martin Truex Jr. took the lead on lap 58. He hit pit road on lap 79 to pit. This handed the lead to Brad Keselowski. He just about missed pit road trying to enter and handed the lead to Matt Kenseth. He ducked onto pit road on lap 82 and handed the lead to rookie teammate Erik Jones. The lead cycled back to Martin Truex Jr. on lap 84. Michael McDowell was tagged for speeding and served a drive-through penalty.[15]

The third caution of the race flew on lap 95 for a one car spin on the front stretch.[16] Exiting turn 4, Jeb Burton got loose and spun down through the grass.[16] Dale Earnhardt Jr. got back on the lead lap being the first car a lap down.[17] Despite having just been on pit road, all of the lead lap cars pitted. Most took just two tires. Joey Logano was tagged for his crew being over the wall too soon. He was forced to restart from the tail-end of the field. Just before the race was to restart, rain started pouring and the race was red flagged on lap 99.[18] Lightning in the area forced the spotters, camera people and fans to get to cover. The red flag lasted for two hours, 15 minutes and 30 seconds.[19]

The drivers were called back to their cars at 10:30 p.m. The engines were re-fired at 10:58. The red flag was lifted and the cars rolled off pit road at 11:00. The race restarted on lap 108. The fourth caution of the race flew on lap 118 for a one car spin on the front stretch. Exiting turn 4, David Ragan got loose and spun through the grass. He came to a rest on the race logo in the middle of the front stretch. Brad Keselowski opted not to pit and took the lead.[15]

The race restarted on lap 128. The fifth caution of the race flew on lap 131 for a multi-car wreck exiting turn 2. Matt Kenseth got sideways after suffering a flat left-front tire exiting 2 and was able to save it. Tony Stewart, trying to avoid Kenseth, got turned by Brett Moffitt into the wall.[20]

The race restarted on lap 135. Brad Keselowski surrendered the lead on lap 164 to pit and handed it to Martin Truex Jr. He ducked onto pit road on lap 176. This handed the lead to Carl Edwards. The sixth caution of the race flew on lap 184 for a single car wreck in turn 3. Going through turn 3, Clint Bowyer came down on Ricky Stenhouse Jr. and spun out. He was tagged again by Stenhouse who was trying to avoid hitting him further and spun around even more.[15]

The race restarted with 77 laps to go. The seventh caution of the race flew for Erik Jones hitting the wall in the tri-oval.[21] Exiting turn 4, his car got loose.[21] He overcorrected and turned head first into the wall.[21] Jones took the car to the garage. “I learned a lot about racing upfront and racing these guys,” Jones said later on Fox Sports 1. “I just got loose off 4 and lost it. It’s my fault. I’m ready to do another one. I hope we get a shot at it.”[21]

The race restarted with 67 laps to go. Denny Hamlin suffered damage on the restart and pitted to repair it. He crashed in turn 1 and brought out the eighth caution with 60 laps to go. “I think we blew a left-front tire,” Hamlin told FOX Sports 1. He was unhappy with how long it took for NASCAR to throw a caution. “I blew it off of Turn 4, spun out, hit the wall at the start-finish line. I keep spinning, keep hitting the wall and I can’t figure out why everyone is still coming at 200 (mph). I look and the green light is on. They didn’t throw a caution until seven seconds after I wrecked. Luckily no one hit us in the door.”[22] Kyle Larson exited pit road with the lead.[15]

The race restarted with 55 laps to go. Kevin Harvick took back the lead with 54 laps to go. The ninth caution of the race flew with twelve laps to go when Stenhouse Jr. slammed the wall in turn 2. Jimmie Johnson opted not to pit when Harvick did under caution and assumed the lead. Paul Menard was tagged for an uncontrolled tire and forced to drop to the tail-end of the field for the restart.[15]

Jimmie Johnson, seen here at the 2015 Daytona 500, scored his 73rd career victory at Kansas.

After waiving the restart with seven to go, the race restarted with six laps to go. Jimmie Johnson held off a hard charging Kevin Harvick for his 73rd career victory.[23]

“It was a long hard night of racing and fighting for track position,” Johnson said. “Once we got up front, we were able to hang on for the final eight or nine laps, whatever it was.”[23] Martin Truex Jr. finished ninth after leading a race high 95 laps.[24] “Yeah, definitely not the finish we wanted, obviously, but proud of the guys for the weekend we had, just had good speed all weekend, brought a brand new car here and just proud of that,” Truex Jr. said. “It's kind of disappointing, but at the same time proud of the way we ran, and I think it's something we can build off of. We should have either stayed out or took new tires. We probably did the worst thing you could have done there with just staying out and getting gas only, because we ended up being the last guy with no tires. Everybody else behind us had two and they ate us up on the restart. If we'd have taken two, we probably would have come out sixth, been in a pretty good position.”[24]
