About this product
2011–2016 Ford Super Duty F-250 / F-350 3" Rear Blocks | Flat No-Taper Steel | USA-Made
Factory rear blocks are a weak point — cast, tapered, and not built for the abuse a working Super Duty takes. The Apoc Industries 3" Rear Blocks replace them entirely with 1/4" fully-welded steel, flat no-taper design, and a satin black powder coat that holds up under load, on the trail, and in the elements. Simple, strong, and built in the USA.
⚠️ Important: These blocks are designed to replace the factory blocks entirely — do not stack them on top of existing blocks. Stacking will cause improper driveline geometry and is unsafe.
Fits 2011–2016 Ford F-250 and F-350 Super Duty, 2WD and 4WD. Sold as a pair.
