2019-2020 GMC Sierra 1500 Denali 1.5" Rear block with shock extensions

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.
