Bushmaster 4x4 Lift Block on Nissan Frontier

Rear Lift Options for the D41 Nissan Frontier: What You Need to know

When lifting the rear of your D41 Nissan Frontier, there are several tried-and-true methods—each offering distinct advantages depending on your goals. Whether you’re upgrading for a camper setup, improving ground clearance, or dialing in a level stance, it’s important to select the right approach for your build.

There are now four main rear lift options to consider:
Add-a-Leaf, Lift Blocks, Extended Shackles, and Replacement Leaf Packs. Below, we break down each method, including pros, cons, and ideal use cases.


1. Add-a-Leaf (AAL)

Add-a-leaf kits add a supplementary spring to the factory leaf pack, increasing ride height and load-handling capacity.

Best For:

  • Builds carrying extra bed weight like campers, gear, or spare tires

  • Preventing long-term rear sag

Pros:

  • Adds load support and lift

  • Durable and reliable

  • Less expensive than full replacement packs

Considerations:

  • Can stiffen the ride when unloaded

  • Requires disassembling the spring pack during install


2. Lift Blocks

Lift blocks are spacers placed between the axle and the original leaf spring, raising the vehicle by lifting the spring pack itself.

Best For:

  • Stock-load trucks needing a modest lift

  • Budget-friendly, easy installations under 2"

Pros:

  • Factory ride quality is preserved

  • Simple, bolt-on installation

  • Cost-effective

Considerations:

  • Requires longer U-bolts, increasing component count

  • Above 2” lift, blocks can introduce axle wrap

  • No added load support

  • More parts = more potential points of failure


3. Extended Shackles

Extended shackles lift the vehicle by increasing the distance between the frame and the leaf spring’s rear mount.

Best For:

  • Lifts up to 1.5"

  • Builds where simplicity is preferred over more hardware

Pros:

  • Fewer components than lift blocks (no U-bolt extensions required)

  • Minimal impact on ride quality

Considerations:

  • Excessively long shackles may affect suspension geometry Resulting in Less effective control of axle movement, especially during compression. Can cause more lateral or fore-aft movement of the axle, reducing stability under load or articulation.

  • The longer shackle hangs farther down than stock, potentially becoming a snag point off-road. This is especially relevant if the truck is loaded or heavily articulated.

4. Replacement Leaf Packs

This option replaces the entire OEM spring pack with a new leaf pack designed to provide lift and/or increased load capacity.

Best For:

  • Long-term solutions

  • Builds needing maximum reliability under load

  • Vehicles frequently used for offroading. 

Pros:

  • Integrated lift with optimized ride and load support

  • No added stress to factory springs

  • Can be tailored to specific weight and ride preferences

Considerations:

  • Most expensive option

  • Installation is more involved than blocks or shackles


Final Thoughts

When choosing a rear lift option, consider how much lift you need, how your vehicle is used, and whether you’ll be carrying extra weight.

⚠️ Important Safety Note: Any lift above 1.5” will likely require extended rear brake lines to prevent overextension under articulation. Failing to address this could result in brake failure.
