Looking to build your bottom end? Ready to turn up the boost? Rods and pistons given the proper research and time can transform how your car behaves, luckily here at Hotboii Factory we have Brian Crower to take the guess work out. State of the art research and design methods as well as high quality materials Brian Crower continues to deliver. You can expect these components to endure a beating whether for Drift , Drag, AutoX or time attack.As you become familiar with connecting rods you will notce that there are two recurring designes the H beam and the I beam. This nomenclature is determined by the shape of the crossection of the connecting rod. That is to say if you were to cut the beam in half across the Horizontal axis (assuming your holding ithe rod Perpendicular to the ground) then examined the newly exposed material it may characteristicly have either the shape of a capital I or a capital H dependent upon where the connecting rod was machined. Machining the Rod allows to lessen the weight and therefore the inertia of the Rod without risking the structural integrity of the rod. Traditionally H beams were the go to aftermarket replacement for high horsepwer drag builds but as metalurgy and machining technology advanced so too did the capabilities of both designs. Great addition to forced induction as well as naturally asipirated engines looking to reliably shift their powerband to the right. Honed down to the tightest of clearances ensuring a perfect fit.
