Anti-Theft Catalytic Converter Shield for 2010-2024 Toyota 4Runner

MPN: CR3896

Catalytic converter theft is fast, quiet, and expensive — and the 5th Gen 4Runner's ride height leaves its converters an easy reach from underneath. This bolt-on Catalytic Converter Shield from Cali Raised LED armors both converters on your 2010–2024 4Runner without changing your factory ground clearance.

304 Stainless — Cut-Resistant and Corrosion-Proof

Laser cut and CNC bent from 12-gauge 304 brushed stainless steel, this shield stands up to saw blades and years of trail spray, slush, and road salt. The circular hole design lets converter heat escape while keeping the guard rigid and rattle-free.

KDSS-Friendly, 100% Bolt-On Fit

Driver- and passenger-side guards install with the included tamper-resistant security hardware and tool — no drilling, welding, or cutting — using factory mounting points. Compatible with most factory and aftermarket skid plates. Fitment may vary by brand and configuration.

Fitment requirements:

Fits both 2WD and 4WD
Works with KDSS and non-KDSS models
Not compatible with 4Runners equipped with the factory X-REAS system. Compatible only after the X-REAS system has been completely removed.

Note:

Do not paint — catalytic converters run hot

Catalytic Converter Shield Installation Instructions — CR3896

Install the Cali Raised LED Catalytic Converter Shield (CR3896) on your 2010–2024 Toyota 4Runner using the instructions below. The shields help deter catalytic converter theft by armoring both converters with 12-gauge 304 stainless, without changing your factory ground clearance.

Fitment and installation time

Fits 2010–2024 Toyota 4Runner (5th Gen), 2WD and 4WD, with or without KDSS. Not compatible with the factory X-REAS system; fits only after X-REAS has been completely removed. 100% bolt-on at factory points; no drilling, welding or cutting. The front tube supports (frame cross braces) are removed and reinstalled. Installation time is not stated in the video.

Included in the kit

Driver-side shield and passenger-side shield
Four supplied 3/8 long bolts, four aluminum spacers, eight large washers and four lock nuts (these replace the two factory crossmember bolts on each side)
Four supplied security bolts and four small washers
Two rubber bumpers
One included security bit

Tools you supply

12 mm wrench or socket (front tube support bolts)
14 mm wrench or socket (transmission crossmember nuts)
A wrench or socket for the supplied lock nuts (the video does not give the size)
A ratchet or driver that holds the included security bit
A pick to seat the rubber bumpers
A floor jack, optional, to support the transmission crossmember while you swap bolts

Before you start

Let the exhaust cool completely before you start. Park on level ground and support the vehicle on jack stands; never work under a vehicle held up only by a jack. The transmission crossmember carries the weight of the transmission: swap its bolts one at a time, or put a jack under it first. Do not paint the shields; catalytic converters run hot. If you run an aftermarket transmission skid plate, take it off first and put it back on after.

Installation steps (driver side first)

Fit the rubber bumpers. Fit a rubber bumper to each shield. Push the small end of the bumper down through the hole in the shield's lip from the top until it locks. A pick helps.
Remove the front tube support. Take out its four factory bolts, two at the rear and two at the front, with a 12 mm wrench. Keep the bolts.
Remove the crossmember nuts. Remove the nuts from the two transmission crossmember bolts with a 14 mm wrench. Leave the bolts in for now.
Swap the bolts one at a time. The crossmember still carries the transmission, so swap one bolt at a time, starting with the loose one, or put a jack under it. For each position: slide a large washer and then an aluminum spacer onto a supplied 3/8 long bolt, push it through from the front, then add a large washer and a lock nut on the back. Loose for now.
Set up the new bolts. Push both new bolts all the way forward. Pull each front washer up to the bolt head and push each spacer back toward the crossmember.
Hang the tube support. Hang the tube support on one bolt, loosely, and let it rest there.
Fit the shield. Lift the front of the shield over the lower control arm bolt, then slide the rear up onto the two new bolts. The washers sit in front of the shield and the spacers behind it; check that no washer has slipped behind.
Start the security bolts. Put a small washer on each supplied security bolt. Start the first one through the front end of the tube support and the shield tab, into the frame, with the included security bit. Start the second security bolt loosely, then the second factory tube-support bolt.
Tighten in this order. Crossmember lock nuts first; this pulls the shield into position. Then the four tube-support bolts. Then the rear bolts and the security bolts with the included bit. Do not over-tighten. If the hardware will not seat the way it should, stop and email support before you force it.
Repeat on the passenger side. The passenger side is exactly the same. Repeat steps 2 to 9 with the passenger-side shield.

Check your work

Both shields sit flat and tight.
All four new crossmember lock nuts are tight.
Both tube supports are back on, with all four bolts each.
All four security bolts are seated; neither shield moves when pulled.

Keep the included security bit safe; it is what takes the shields back off.

Need help?

If the hardware will not seat correctly, stop before forcing it and contact support@caliraisedled.com.

The peace of mind is tangible and the sense of accomplishment is rewarding. I do not ever have to worry about any theft and paying the price for someone else's misfortune to need to steal. These are stout in design and material. As with anything the first one took 2 hours and the second took 20min- Super easy install and the video helps tremendously. I am super happy with these! Go get you some

Thanks, Marc! Glad the Catalytic Converter Shield gave you the added peace of mind you were looking for and that the install video helped make the process easier. We really appreciate the feedback on the stout construction and your recommendation.

Easy Install

The installation was pretty straightforward after watching the video. However, after installing the passenger side, I was left with no washers to complete the driver side, so I had to run to the hardware store to get more. Other than that, I love these shields. Hopefully, my next order doesn't come with missing hardware.

Great protection

Amazing product and hopefully slows down the thief's and roaches from stealing. Entire install took less than . 60 mins

Great theft deterrent

These are well made and fit up well with my 2023 TRD off-road. Installation was really easy with the help of the video that Cali has, that video totally made a difference, keep up the great work.

The guards themselves fit well, don't rattle and restrict the access to the cats for the most part. I think that they will work as intended and just encourage the thieves to move on to the next one. I do think that someone with a sawzall and a long blade could still cut and remove the cats from the rear, there is enough exposed pipe in front and behind the guards/frame that it could be done but again it probably is enough discouragement to make them look elsewhere

Overall for the cost I'm still happy that I put them on and would do it again.

Purchaed our 3rd set of

Purchaed our 3rd set of CatGuards and multiple light bar kits from CalRaised. Awesome to deal with and on the ball!

Awesome product

Super easy to install. This is my third set for 4Runners and Tacos. Adds that armor to keep the theives at bay. Happy to have them instead of a ridiculous insurance claim and a vehicle you can't drive.

Great product! The best value in the west

Quality product. Precision cut metal. Shipping was fast. My kit came with 4 missing washers but a quick trip to hardware store solved the situation. I highly recommend these shields.

Awesome Product!

I installed my Cali Raised Catalytic Converter Covers that I received a while back. Shipping was very fast, and everything was packed well. Both sides fit perfectly, and installation was a breeze. I did install an extra washer or two on the outside transmission bolts to help align the front rubber bumpers to my frame. Placed my jack under the transmission bracket and put light pressure on it until both bolts were loose making swapping of the bolts easy. Also, I left one of the rear crossmember bolts loosely installed so I could just swing the crossmember out of the way and then swing it back to help the install process. I could not find extra secure bolts on the Cali site, but I will find some and install them soon. Very happy with this awesome product and the peace of mind!

These catalytic converters look great.

These catalytic converters look great. Took me 2 hours to install the driver side. (Just because it was my first time and I’m a beginner). But process was fairly simple after watching an install video. I was able to install the passenger side in about 30 minutes. I feel more comfortable with having these installed.

East install

Super easy to install and although nothing will stop a determined thief, I feel a lot better having a vehicle that's easy to get under.

2020 4Runner TRDPro Cat Shields

Got this after someone attempted to steal the cats on my Sequoia. My wife has a 2020 4Runner that this install was way smoother and looks way better than the one I put on my Truck. Video was super helpful for the install and they even included the security bit needed for the specialty torx bolts. Very happy with this purchase, how easy it was to install and the quality of the product. Not to mention it only took 2 days to get to me from the time I ordered. Thanks all!

Excellent!

Very impressed with the quality and ease of installation! 2019 4Runner with kdss, took about an hour and that’s with gathering everything needed for the job.

Piece of mind

These are very easy to install. Easy steps to follow to install. Most of all you have a firm sense of peace knowing that your calculator converter is secure.

Great product!

Great build quality and craftsmanship! Took several weeks to get, due to lead time and high demand, but well worth the wait!
Installation at my mechanic’s shop took 20 min after watching the video.

Buy em!

Great product. It shipped quicker than expected. Install was pretty easy. I would suggest a hack stand to hold it in place while your other 2 hands are bolting it up.

2023 T4R TRD ORP with KDSS

Easy and quick install on my 2023 T4R TRD ORP with KDSS. No issues whatsoever and great peace of mind. Not sure why there’s so much misinformation on if the shields are/are not compatible with some models. Hopefully this review helps some.

Excellent purchase

Received my set of shields a few months ago and finally had time to install them. Outstanding fit and finish and priceless piece of mind.

Fits like a glove!

Watch the installation video, follow it, and you'll be just fine. Great product that provides great protection for your cats!!

Good - could be slightly improved - very slow shipping

Overall the product is made and designed well.

One of the rubber bumpers didn’t align or contact my frame at all. This could be a frame issue so that’s understandable. Another cut hole inboard of the current ones would solve this and allow more flexibility with install.

I manually bent the tab to ensure contact.

CR Engineering did reach out after I submitted an inquiry so that is good and they took my feedback well.

Shipping was double what the lead time stated on website and support didn’t have a clue on actual shipping. Kept being told “end of this week” and then nothing. If it’s delayed then just say it up front.

I was offered a small rebate for the shipping delay so that was nice.

I would order from them again without hesitation.

Excellent customer service

Excellent quality and service. I ordered by phone and the service was perfect. I was impressed with the quick response and time it took to arrive. This truly a company that goes above and beyond to produce great products at an affordable price and ship out to customers in a quick timely manner. Thank you caliraised.
