ICON Vehicle Dynamics 1" Cast Iron Rear Lift Block Kit for Ford F-250/F-350 and Nissan Titan XD

The ICON Vehicle Dynamics 1" Cast Block Kit adds 1 inch of rear lift height using heavy-duty cast iron blocks with integrated center pins, fitting 2008–2026 Ford F-250/F-350 Super Duty and 2016–2024 Nissan Titan XD trucks. On Titan XD models, which do not ship with factory rear blocks, the kit provides a straightforward path to rear lift. On F-250 and F-350 Super Duty trucks, the blocks are designed to pair with ICON's 2" Lift Leaf Spring Expansion Packs to maintain near-stock ride height while reducing axle wrap.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Cast Iron Construction for Long-Term Durability

The lift blocks are cast iron rather than fabricated steel or aluminum, which means they resist deformation under the sustained load and flex cycles a heavy-duty truck rear axle generates. A semi-gloss black paint finish adds a layer of corrosion resistance so the blocks hold up in wet or road-salt environments without surface rust compromising the fit against the axle pad or leaf spring pack.

Center Pins Simplify Installation

Each block includes integrated center pins that locate the block precisely between the axle pad and the leaf spring pack, eliminating the need to source separate locating hardware. Correct pin alignment keeps the axle from walking under load, which matters on a truck used for towing or hauling where lateral forces on the rear suspension are highest.

Axle Wrap Reduction When Paired with ICON Leaf Spring Expansion Packs

On 2008–2026 Ford F-250/F-350 Super Duty, running these blocks alongside ICON's 2" Lift Leaf Spring Expansion Packs produces a meaningful reduction in axle wrap compared to the factory leaf spring and block combination. Axle wrap under hard acceleration or braking causes the driveline to oscillate, which accelerates U-joint wear and produces the characteristic shudder some owners notice when towing a heavy trailer from a stop. Reducing it improves driveline smoothness without requiring a full suspension overhaul.

Specifications

Who This Is For and Isn't

This kit suits owners of 2008–2026 Ford F-250/F-350 Super Duty or 2016–2024 Nissan Titan XD trucks who want 1 inch of rear lift. On Super Duty trucks, it is specifically designed to work alongside ICON's 2" Lift Leaf Spring Expansion Packs for near-stock ride height and reduced axle wrap.

This kit does not fit vehicles outside the stated 2008–2026 Ford F-250/F-350 Super Duty and 2016–2024 Nissan Titan XD fitment range. The leaf spring expansion packs referenced are sold separately and are not included in this kit.

Common Questions

Do the center pins come included, or do I need to source them separately?

The ICON 1" Cast Block Kit includes center pins as part of the kit. No separate locating hardware is required for installation on the supported Ford F-250/F-350 Super Duty and Nissan Titan XD fitments.

Does this kit work on the Nissan Titan XD without any other ICON components?

On 2016–2024 Nissan Titan XD trucks, which do not come with factory rear blocks, the 1" Cast Block Kit can be used on its own to add 1 inch of rear lift. No additional ICON leaf spring components are required for the Titan XD application.

What is the purpose of pairing these blocks with ICON's Leaf Spring Expansion Packs on the Ford Super Duty?

On 2008–2026 Ford F-250/F-350 Super Duty, combining the 1" Cast Block Kit with ICON's 2" Lift Leaf Spring Expansion Packs is designed to maintain near-stock rear ride height while delivering a ride quality improvement and a reduction in axle wrap versus the factory leaf spring and block setup. The expansion packs are sold separately.
