I've tried searching and have been unable to find an answer to the following question. Does anyone know how big of a budget boost (puck) you can put in before bumpstops are required to prevent over compression of the factory springs? I've got a 2dr running some JKU springs for a lift plus daystar 3/4 inch pucks. I'm wondering if I can put larger pucks in without bumpstops or what the smallest ones are that I can use. I realize that's a pretty technical question for the factory springs but hoping someone on here knows what it is. Thanks!!

 

The Teraflex leveling kit has 2 inch spacers in the front and 1 inch spacers in the back with no bumpstops. But their 2.5 inch bb has bumpstops. So my guess is that 2 inches is the max.

 

All the 2" budget boost kits have bumpstop extensions... So it keeps the same proportions I bet. If you've got 3/4 already you're almost 1/2 the BB. I'm not sure the exact answer to your question but based on the BB kits I wouldn't go much higher without the extensions.
