Giant Motorsports I Beam kits. If you are looking to construct your own beam kits, you will want to check out the equal length beam pivots. These pivots are the hardest part to get the right position and to construct when doing this style of kit. Save yourself a lot of time and headache and just bolt this part and get straight to making your beams. The Giant Motorsports Prismatic I Beam has been changed with the construction design to eliminate the tubing and are are all now plate work.
