Artec Industries is excited to announce the TJ 8.8 Axle Swap Kit. This heavy duty truss and bracket system is designed to take serious abuse and reinforce your entire axle while also providing the factory link, anti-sway bar, and shock locations. The 1/4 inch thick truss top incorporates a unique design to strengthen both the axle and incorporate the link brackets for ease of installation and added strength. By incorporating the link mounts into the truss, hours of work and trial and error can be avoided when compared to other bracket systems. Simply tack weld the truss together, place it on the axle and all the other brackets fit into place exactly where they need to be. The Ford Explorer 8.8 features: same lug nut bolt pattern as Dana 35, 3-1/4 inch diameter tubes as compared to 2.625 inch Dana 35, disc brakes (1995 & newer), 31 spline axle shafts, 8.8 inch diameter ring gear which 120 percent stronger than Dana 35, only 20 pounds more than Dana 35, and a trac-loc differential stock. When swapping, the 3.73 gear ratio may need to be changed to match your Jeep gears and wheel spacers may be necessary to bring the width back to factory specs since the 8.8 is 1.25 inch narrower than the Dana 35.
Details:
- Sold As Each
- Features include:
- 1/4 inch thick mild steel truss and brackets for much higher strength than the factory bracket and other aftermarket brackets.
- Precision CNC cut and bent for great fitment.
- Includes all the brackets necessary for a complete axle swap including upper and lower control arm mounts, shock mounts, anti-sway bar mounts, tracbar mount, and coil spring mounts.
- Save hours of installation time. Brackets are jigged into truss and set exact position automatically. All other brackets just need to line up to truss, no guessing and measuring involved.
- Trackbar mount includes both factory location and lifted bracket location for those who have aftermarket lifts.
- Truss is reinforced using interlocked 1/4 thick gussets for maximum strength and easy assembly.
- Overall low profile design means your axle is stronger, sleaker, easier to fit into any vehicle, and less likely to interfere with vehicle components.
- This kit requires general welding and fabrication skills. Welding should only be done by a competent welder.
- Artec Industries implies no guarantees or warranties and is not liable for improper installation.
- *Some grinding and fitment may be required when installing this kit.
- Every axle varies slightly and some fabrication may be required.
- Will require brake line relocation to fit.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

I want to take the time to share my experience with Core 4x4.
I have a 2004 Jeep Wrangler and was looking to upgrade some suspension parts. I went with Core 4x4 upper & lower adjustable control arms and a front adjustable track bar. Everything arrived quickly, and right out of the box I was impressed with the quality and craftsmanship.
I had a few questions during installation (measurements and torque specs), and I spoke with Korby on a couple of occasions. Not only did he send me detailed instructions, but he also shared an installation video specific to the part and vehicle I was working on, something you don’t get from many companies.
The control arms fit perfectly, look great, and perform exactly as I hoped. I did run into an issue with the front track bar touching the front diff. When I reached out, Korby had me send pictures and then immediately offered two solutions: his bar guy could make a different bend and send it out to me, or I could get a full refund. His response honestly blew me away. As much as I wanted to run the Core 4x4 track bar, I chose the refund. Korby sent me a prepaid shipping label right away, no hassle.
My experience with Core 4x4 has been excellent. Korby was extremely understanding, communicative, and helpful every step of the way. The parts I received were high quality, and the customer service was second to none.
I would absolutely recommend Core 4x4 10 out of 10 times and will be using them again. Just a great American company with awesome people who truly care about their customers.
Thank you Korby, and thank you Core 4x4!

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues.
I would highly recommend CORE 4x4 to anyone looking for a great quality kit.

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement.
Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect.
Would highly recommend giving these guys a call.

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts.
All around just seems like they don’t care.

I don’t write reviews often, but Core 4x4 absolutely earned this one.
I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts.
That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed.
The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots.
Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right.
If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.
