What’s Needed for a 2IS to 3IS Conversion?

Lexus 2IS to 3IS conversion usually is about swapping the front bumper from 2IS look to 3IS look. Of course, the conversion can be taken to the next level with other stuff, but usually people leave it as it is with just swapping the 2IS front bumper to 3IS front bumper.

Converting the rear end and even the interior of course is possible. These jobs just are so costly and time consuming that usually it is not worth it and if you are considering doing the conversion to that level, maybe it should be better to just buy a 3IS Lexus.

🔧 Required Parts List

  1. 3IS Front Bumper Cover (OEM or aftermarket)
  2. 3IS Bumper Reinforcement Bar (or modified 2IS bar)
  3. 3IS Headlights (or use 2IS lights, then you need custom brackets)
  4. 3IS Grille (upper and lower)
  5. 3IS Fog Lights & Bezels (or delete kit)
  6. Bumper Retainers & Clips (often sold in a kit)
  7. Conversion Brackets (for proper mounting)

Step-by-Step Installation Guide

🕒 Estimated Time: 6-10 Hours

(Depends on DIY skill level and whether you’re reusing 2IS headlights or upgrading them to 3IS. Upgrading headlights may need coding.)

🔨 Step 1: Remove the Old 2IS Bumper

  1. Disconnect the battery. Disconnecting the 12V battery is advised anytime you do any work for your car.
  2. Remove the front wheels (for easier access).
  3. Look for bolts that need to be unscrewed and take out the grille, fog lights, and headlights.
  4. Unbolt the bumper from the fenders and reinforcement bar.

It helps to get the car lifted at least a bit.

🔧 Step 2: Modify or Replace the Reinforcement Bar

  • The 3IS bumper is wider, so you’ll need:
    • 3IS reinforcement bar (best option), or
    • Modify the 2IS bar with a cutting/welding kit.

⚙️ Step 3: Install the 3IS Bumper

  1. Test-fit the 3IS bumper before final mounting.
  2. Secure it to the fenders and reinforcement bar using brackets and simply bolt it in.
  3. Install the 3IS grille and fog lights.
  4. Adjust headlight alignment (if using 3IS lights).

🎨 Step 4: Paint & Final Adjustments

  • If the bumper is unpainted or different color, get it color-matched.
    • IF NEEDED, IT IS RECOMMENDED TO PAINT THE BUMPER BEFORE INSTALLING IT
  • Reinstall all trim pieces and ensure proper panel gaps. Alignment may take some time, but it should be done properly so there are no big or different sized gaps between the new 3IS bumper and other boy panels.
