BDS guarantees there lifts for life. No questions asked. I have a 4.5 inch with 35's and am super impresses by it.

 

If you guys had to compare would you say that BDS is comparable to TF? Im looking at a 3" kit for my JKU. Thanks

 

I can't say on the TF kit , but I love the BDS kit.

 

Teraflex!!!

 

Have mine installed and it's great! It was a little stiff when it was first installed but better now a couple of weeks later. The 4" kit came with nice parts and easy to follow instructions. Measured 4 1/4" when first installed but is now right at 4".
