2in BB's (budget boosters) are basically just very thick slabs of polyurethane that sit atop your springs. Jack it up, unbolt the shocks, compress the springs down some, and slide them in to fit on top of the springs. POW!, you've got 2 inches of lift. (I was able to install BB's (not RRO) on my WJ without compressing the springs. Be creative and u 2 can do it!) You can go with stock shocks because the lift is minimal and longer shock mounts are supplied. Ride difference shouldn't be too noticeable. I run Old Man Emu shocks and would buy them again; they are well worth the money and the ride is smooth. Directions with RRO's BB's are minimal, but in this case there isn't much to do except see that you need to get the BB's on top of the springs. The shock mount drops are easy. Pull yours out and replace with what was supplied.
Word of advice: Do a search for "RRO" or "Rocky Road" on this site to view statements from the many that have been burned and thoughtful enough to share their experiences with purchases from RRO and/or their products.
I rate a 4 because of who sells them and their delayed shipping. Instead, send an email to firstname.lastname@example.org
for anything you need. Quick. Dependable. Knowledgeable.
