No, this is not necessary on blocks less than 3” in height. No change in pinion angle is required for 1-2.5” of lift.
Suspension MAXX block and U-bolt kits use high-quality blocks from SOLID STEEL, unlike the cheaply made hollow cast import lift blocks. Each of our blocks is precision cut and CNC machined. We also use All- American made steel U-bolts, Tall Nuts, and Heavy Duty washers.
Factory shocks have 8-12” of shock travel and can work well with 1” and 1.5” of lift on most trucks. 2” of lift is the maximum height of lift we recommend; it depends on the application as some vehicles like F150 trucks have extremely long shocks from the factory. Shock extensions or longer shocks will be needed for sharp drop-offs, like speed bumps, for example.
Yes, the 1.5" rear lift will leave 1.0" of rake when installed in combination with our 2.5' front leveling kit.
