don't waste your time with it.... the eibach front coils are garbage as the coils touch after installation. this can cause big problems for you. you will only end up replacing them in the future.
For all 99-03 Ls:
Front springs 1.5" drop 3576.520
Rear Hanger Kit 2" drop 3576.920
Rear Shackle Kit 1.5" drop 3811.820
I have all 3 and the truck is almost level. The rear shackles have 2 holes, a 1" drop and a 1.5" drop. I need to drop mine to the 1.5" drop hole and she should be level.
