How to Build the Ultimate Custom Land Rover Defender in 2026
Building a custom Land Rover Defender is not just about restoring a car; it is about creating a vehicle that fits your life perfectly. But with so many options—engines, transmissions, chassis sizes, and roofs—it can be overwhelming to know where to start.
At Shoreline Vehicles, we believe an educated buyer is our best client. That is why we have created this "Master Guide" to walk you through every critical decision in the build process for the year ahead.
If you are planning a build in 2026, here are the 5 big decisions you need to make (and the guides to help you make them).
1. Choose Your Chassis: The 90 vs. The 110
The first step is deciding on the footprint. Do you want the agile, sporty 2-door, or the commanding, family-ready 4-door?
The Defender 90 is the nimble choice. It’s perfect for city parking, couples, and weekend beach runs.
The Defender 110 is the grand tourer. It offers unmatched stability on the highway and enough cargo space for a week-long expedition.

2. Choose Your Transmission: Manual vs. Automatic
For decades, the Defender was a stick-shift-only vehicle. Today, you have a choice.
The Purist: A rebuilt R380 5-speed manual gearbox keeps you connected to the machine. It’s engaging, fun, and authentic.
The Modern Driver: A GM 6-speed automatic transmission (paired with an LS3 V8) makes the Defender as easy to drive as a modern SUV. It’s perfect for traffic and daily commuting.

3. Choose Your Power: Gas V8, Diesel, or Electric?
The heart of your build dictates its soul.
The V8 Restomod: Our most popular option. A 430HP GM LS3 V8 gives you modern highway speeds and reliable power.
The Electric Future: For the ultimate in silence and torque, a Tesla-powered conversion makes your classic 4x4 zero-emissions and future-proof.

4. Navigation: The "California Question"
If you live in a state with strict emissions laws (like California, New York, or Colorado), you cannot just build any truck. You need a build that is 50-state legal.
The Shoreline Solution: We specialize in CARB-compliant builds using the GM E-ROD system. This ensures your powerful V8 Defender can be legally registered, smogged, and driven without fear of the DMV.

5. The Financials: Investment vs. Expense
Finally, you need to consider the long-term value. Unlike mass-produced luxury SUVs that lose 50% of their value in three years, a custom Defender is a finite asset.
The Shoreline Promise: We build vehicles with such high standards that we frequently buy them back from clients. Buying a custom Defender is parking your money in a legacy asset, not throwing it away on depreciation.
