Front radius arms - Caster correction kit – Toyota Land Cruiser 80

🔧 Caster correction & optimized geometry after lift

The Delta VS caster correction front radius arms are designed to restore proper geometry on Toyota Land Cruiser 80s equipped with a lifted suspension.

From a 2” lift, it is common to notice:

❌ Unstable steering
❌ Poor steering wheel return
❌ Vague feeling at high speeds
❌ Loss of straight-line stability

These radius arms allow you to regain stable and precise handling, close to factory specifications.

📏 Versions available

Compatible with 50mm to 150mm lifts.

Two lengths to choose from:

🔹 REGULAR version

• Slightly longer than stock
• Maintains original wheelbase
• Recommended up to 35" tires

🔹 LONG version

• +1” longer than stock
• Moves front axle forward
• Reduces the need for body trimming
• Recommended for 37"+ tires

⚠️ IMPORTANT:
The long version does not change caster correction.
A 3" arm and a 3L arm correct the exact same value.
The difference is solely in length for tire clearance.

🏁 Technical advantages

✔ Precise caster correction
✔ Restoration of road handling
✔ Retention of wheelbase (Regular version)
✔ More travel than stock radius arms
✔ Reduced width to avoid interference

Unlike correction plates, these radius arms:

• Actually correct the geometry
• Maintain stability
• Optimize overall handling

🛠 Construction

• Laser-cut steel
• 100% made in the USA
• Semi-gloss black powder-coated finish
• Option with new bushings installed
  

⚠️ Model selection – Recommended method

The manufacturer recommends the following procedure:

1️⃣ Install the lift
2️⃣ Load the vehicle in its typical configuration (95% of the time)
3️⃣ Measure caster without correction
4️⃣ Compare to OEM values: +3° ±0.5° (i.e., +2.5° to +3.5°)
5️⃣ Choose the appropriate radius arms based on measurements

⚙️ Important technical note

Around a 4” lift, some users may notice:

• Driveline vibrations
• Poor pinion angles

In some cases, 3” radius arms may provide a better compromise between:

✔ Caster correction
✔ Pinion angle
✔ Comfort
