ALL THINGS SLINGSHOT as the exclusive Distributor / Manufacturer of TrakHamr™ Products is pleased to introduce the latest version of the tried and proven TrakHamr™ Quad kit.  

Using the same FRP Transverse Leaf Spring, Independent Rear Suspension, and Driveline attributes that have propelled North America's top Sports Car, the Chevrolet Corvette into stardom, TrakHamr™ has perfected a quad conversion utilizing those off the shelf GM C4 Components to give the Slingshot the same outstanding Corvette Suspension performance Still in use on every award winning Corvette design today. 

Improving on their tried and proven TrakHamr™ Design, Engineer , Designer, Troy Hill has modified his tubular chassis design to include a weld free, bolt on, assembly. That simply allows the assembled TrakHamr™ unit to be rolled right into place beyond the original swing arm pivot points, incorporating all the structural Polaris integrity of the angle drive mounting points, including the swing arm pivot points to create a torsional box design unparalleled in the industry today.

The transverse composite leaf spring spans the width of the rear end and serves both sides. Interestingly, this makes the transverse spring itself something of an antiroll bar, enough so that even today, the base C7 Corvette without the Z51 package doesn't even have a stand-alone rear antiroll bar. 

The advantages of the Corvette's transverse composite leaf spring include these: very low weight, very low unspring weight, no need for reinforced structures up high, low center of gravity, height and corner weight adjustability, built-in roll stiffness that reduces the size and weight of the stabilizer bar. 

The TrakHamr™ Self Install Quad kit, comes with the complete Driveline Unit, finished in Wrinkle Black, and fully assembled. The tubular chassis is available in Powder coated color of purchaser's choice with a third color available as an accent on the Control Arm Links, Rear Toe Links and Anti Sway Bar ,
