I have a 2015 Duramax 2500 and was looking at coilover conversion kits. Upon my research so far I have found that the tallest kit is the BDS kit that goes up to 6.5 inches. I need a total lift of 8-9 inches in the front so I was wondering if anyone knows of a kit that can help me achieve that or can direct me to someone that has done it. Thanks!

just curious why you need your total lift to be 8-9 inches? The BDS kit allows to fit 37s as per their website, which most likely means 38s arent an issue in the real world

I agree that if you want that much lift you should look at doing a solid axle swap, unfortunately with big lifts IFS engineering becomes much more complicated.

Thanks for all of the responses. The reasoning behind wanting an 8-9 inch lift is because we are trying to fit 40x15.5s. We are using a 2015 Duramax chassis and are using the body of a G Wagon so it needs a slightly different lift for 40s. Also, we wanted to stay with the IFS for the sake of a smoother ride so I will most likely go with a traditional 8-9 inch torsion lift rather than solid axle swapping. Right now I'm leaning towards the CST 8-10" lift

You can make it ride as smooth or better then ifs FYI. Shock tuning suspension radius goes a long ways. A lot of misconceptions on sas being rough

You can make an SAS ride great, just requires a lot more money than a cheap solid axle lift.

I have good history with FTS (full throttle suspension) and their kits. Limitless options and customizable. I wouldn't say they are well suited for crazy off-road use, although i did some mud and a little rock stuff without issue. They have some extreme kits where you can fit crazy setups. Their 9-11" gave my 03 clearance for 38x13.5 toyos on 22x12s

I've got that kit on my 2019 2500 and the 37s barely fit if you have AMP steps. They hit the steps if you hit a bump at full turn.
