No. You'd need longer shocks, such as the extended-length Donahoe coilovers, that could handle the 1" extra downtravel. And no, you wouldn't necessarily need a diff drop at 2.5" of lift.grntaco said:If I used the All-Pro A-arm with stock springs would it still give 1" more travel and would I need a diff drop with 2 1/2" lift combined with the A-arms? Thanks
