Rear Lift Block FAQs

Q: What are lift blocks? 

A: Lift blocks raise the rear ride height of your leaf-sprung vehicle. These simple alloy blocks mount between the leaf springs and axle tubes, increasing the distance between the axle and the body and, thus, the body and the ground! 

Q: Are lift blocks safe?

A: Yes! High-quality lift blocks are perfectly safe; they’re even the included lift option on several entry-level lift kits. When installing lift blocks, it’s essential to pair them with appropriately sized U-bolts to ensure adequate clamping force. 

Q: Do lift blocks affect ride quality? 

A: No! In most cases, lift blocks retain your vehicle’s original ride quality, considering no other components are altered. However, depending on the size of your new lift blocks, you may need to upgrade to longer rear dampers.
