Product Description

The Z1 Rear Differential Brace provides additional support for the rear differential in your Nissan 350Z or Infiniti G35, preventing drivetrain damage and wear during spirited driving.

Your 350Z / G35's rear differential is mounted to the subframe using a single offset mounting stud in the differential cover. Factory differential bushing and mounting stud are prone to fail, and these issues are exacerbated on modified cars that are frequently abused or launched. In more extreme cases we have seen cars either break the factory differential cover or break the mounting stud. When failure occurs, the differential separates from the subframe, breaking inner axle joints and damaging your exhaust. To prevent this failure, we have developed the strongest differential brace yet. By utilizing cast 304 stainless steel, we were able to manufacture a brace without the possibility of failure from welds or joints. The Z1 Differential Brace utilizes a pre-existing hole in the rear subframe to provide additional support. The additional support reduces strain on the differential cover and stud while simultaneously aiding in the reduction of wheel hop and driveline slop.

Our differential brace was designed to work specifically with the Z1 High Capacity Differential Cover, however, it is still compatible with the Nismo and factory differential cover!

  • Cast 304 Stainless Steel

  • Includes All Hardware

Installing was super simple. Took probably less than 15 min on a garage floor

Easiest mod and install! Helped me out while I replaced the diff bushing.

Great quality part! Just installed it on my 05 350Z and probably saved the diff from collapsing. Very easy installation.

Super easy install. I can feel a noticeable difference with a solid second point of contact to the subframe. I threw some loctite on the top bolt that bolts to the subframe for safety

Great idea. The only part that sucks is you have to keep the cover bolts loose so you can line up the diff brace bolt thru the frame. If you leak, now you have that problem. Maybe it's me but if you use the finned diff cover couldn't you crack that cover if your main bushing is bad?

Stiifened up my driveline and adds a nice jacking point on the rear of the car for quicker brake jobs and what not.

Great quality, fairly easy install, on the g35 sedans the long bolt is a pain to get into the subframe because of the spare tire area of the trunk. Little persuasion and we’re in business.

Love this product! This diff brace increases more of gear noises. For those who don't mind with gear noises, like me, get this product! I purposely look for some gear noise. Sound like a race car You must install solid subframe bushing or solid diff bushing along with this part, you will hear gear noise for sure. I don't find any improvement as far as performance because my Z has other bigger mods that support its chassis. My purpose of the review here is for NVH concern.

One of the easiest and best suspension mods for the 350z. Keeps the differential a lot more planted. Highly recommend looking at a video of how much the differential moves and why this brace is a must have. Also will hopefully prolong the life of the differential bushing!

Quality of the parts are of good quality. The instruction video is helpful, but a bit disappointed that there were no written instructions to download. Written instructions are important for such a unique part.

Extremely easy to install and gives me the confidence to really push my car at the track and not worry about the single stud that the 350z comes with.
