4" Kit | 2024 AT4 HDFit perfectly! Swapped the front differential for a 2019, with 2019 axles, to get a 4.10:1 gear up front to match the new rear. Furthermore, running a 1" diff spacer, setting it to 5" and maintaining the 3" of droop travel (Justin). What a well thought out kit. Thank you, Cognito, once again!
