This gusset kit will not work on models with a smart lock front diff or Halo full billet diff, you will need to purchase our smart lock gusset kit instead.
The X3 gusset kit is a great add on and a must for hard drivers or people that want to keep their machine straight and true. It adds rigidity and strength to the front of the machine and is going to be a must for people wanting to add a winch to the front of their X3.
We started our kit with a higher grade steel than most use, grade 50 over the common A36. Grade 50 has a higher yield and tensile strength than A36 plate, combined with a lower weight making it a stronger and better option for our gussets. While A36 material isn’t a terrible option its also not our first but what others tend to use due to cost. It tends to stretch and when you’re trying to use this material as a gusset it’s less than ideal. You won’t find many places advertising their material choices and why.
Our kit consists of 6 individual pieces plus hardware, 5 plates and a billet aluminum block.
We’ve created a plate system that ties the front mounting points along with the upper rear mount together in full via 4 different places and a machined piece of aluminum. The front of the X3 is what we call a floating front end. The front of the chassis ahead of the front a arms attaches via the front arms and is only supported by the radiator. If you were to pull on that that portion of the frame you’re pulling on the front suspension bolts only, its a risky move. Our billet aluminum block mounts between 2 pieces of plate steel inside and out that keep that front section from twisting and also from pulling solely on the a arm bolts. This is the same void in the frame where the front of the a arms pivot. The front of the frame no longer floats at this point and is tied into firmly with the rest of the chassis. Above the diff we have 2 different pieces of metal that tie the rear upper pivot point to both front a arm points. This not only strengthens the frame from the bolts trying to pull out but it greatly reduces the chance of the frame twisting. The final plate piece is additional reinforcement to to the rear lower mounting points of the suspension and finishes the gusset kit.
Standard install time is roughly 3 hours and a mechanical background or general handy work is advised. The majority of the front suspension needs to be removed along with the diff loosened up to move inside the frame. Detailed instructions with pictures are included.
