Smith Ti New 7075 Billet Aluminum Left Rear Torsion Arm – 3-1/4″ Offset
~The purpose of this new aluminum arm is again SAFTEY & STRENGTH!
~Although no aluminum arms are a rival to our titanium arm, we’ve built the second safest arm available. Again just like our titanium version we have done all the work for you, NO torsion bar adjustments, NO ride height changes. Just bolt on, block the same and go race.
~In past history the splined area on the aluminum torsion arms has caused many injuries by breaking at the spline and letting the rear end come loose and move in the car. Using advanced technology in computer aided designing methods with stress analysis while also using a stronger aluminum alloy 7075, machining a short tapered shock spacer and addressing the problematic splined area we have been able to eliminate a few of the major problems the cheap/inexpensive aluminum arms have had.
~The life of these arms may see 50 or more races with no twist.
~Available in polished aluminum also by special order
~These arms are fully machined from a solid block of aluminum NOT bar that’s bent into shape. Bending aluminum destroys the material and causes arms to give up in as little as 5 races!
