4” BDS lift

[timothycan]

A while back I had installed a Superlift 3” lift/level most and replaced Ranchos shocks with Billstein 5100 front and back.   
 

Yesterday replaced that with a complete 4” BDS suspension lift.  Shop called me and said the rake from front to rear was a 2 inch difference.  BDS had assured me I’d get the 4 inches with the Billstein set at stock.   It should be no more than an inch of rake.  
 

the 3 inch Superlift did the same thing.  
 

my question to you guys is, has anyone lifted a 2021 GMC Sierra with the 3.0 duramax and got the correct amount of lift? 
 

if so did you keep your Ranchos or use different shocks?

 

foe the life of me neither myself nor the shop doing the work can explain the rake difference after installing these kits.  
 

thanks for the help.

Not sure, but the diesel is a heavier engine, that might be why you have the increased rake.
