After some of the heaviest contact and hardest crashes of the year, the Smith Ti Torsion arms have not failed.

Titanium torsion arms offer a number of advantages over aluminum – they’re lighter and they’re stronger. But, the biggest advantage is the titanium arms stay intact at the splines after a crash protecting the driver’s back and keeping the rear end in place. These two details make the titanium arms safer than aluminum.

Other benefits of the titanium arms is that they are designed with the same spring rate as aluminum and teams can use the same torsion bars and set up blocks. Also, with the location of the shock, you don’t need a spacer because the the profile is so small the shock body can sit over top of the arm (even for large body shocks),eliminating excessive arm twist from the shock. The heat from the exhaust doesn’t affect titanium either. Because the arm is made from a solid chunk of material it isn’t compromised by bending – and the memory of these arms is insane! They can bow and bend and still come back to home.

The pictures show their strength. The machine work is beautiful.
