Rock Krawler RK08908K 4.5" Fabricated Rear Lift Blocks - Sold As Pair

The Rock Krawler RK08908K are heavy-duty fabricated 4.5" rear lift blocks engineered for the Ford F450 Super Duty. Precision formed from ¼" thick laser-cut steel and fully boxed for maximum structural rigidity, these blocks are TIG welded and finished in a durable black powder coat to resist corrosion and withstand the demands of serious off-road use.

Unlike stacked or aftermarket add-on blocks, these are designed to completely replace the OEM lift block, eliminating dangerous block stacking. The integrated bump stop striking pad is repositioned specifically for 4.5" lift applications to help minimize tire rubbing when running larger tires.

Key Features:

• 4.5" block height for substantial rear lift
• Fully boxed 1/4" thick laser-cut steel construction
• Integrated bump stop pad — relocated for 4.5" lift compatibility
• Precision TIG welded for superior strength and durability
• Durable black powder coat finish
• Replaces OEM lift block — no stacking required
• Sold as a pair
• Designed for 4WD applications

Rock Krawler fabricated lift blocks deliver a safe, strong, and clean alternative to stacking blocks, giving your Super Duty a reliable rear lift with improved geometry and fitment for larger tires.
