Racking up 11-second time slips used to be a nearly unattainable goal for weekend warriors, but it’s now commonplace to see street driven muscle cars pulling the front wheels and breaking the 10-second barrier thanks to modern launch controls and powerful new engine tech. Cars running this fast must meet strict NHRA safety regulations, one of which is the requirement for a driveshaft loop. Trans Dapt Performance now offers affordable and easy to install NHRA-compliant driveshaft loops for 4th-Gen Camaros, Firebirds, and Trans Ams, Fox-Body Mustangs, and a universal bolt-in application.
NHRA rules require a driveshaft loop on any vehicle that runs the quarter mile quicker than 13.99-seconds while running slicks or quicker than 11.49-seconds on street tires. The reason for this requirement is to keep the driveshaft from digging into the ground or piercing the floorpan of the vehicle in the event of a front universal joint failure, possibly causing a sudden loss of vehicle control or serious injury to the driver. To comply with these rules, Trans Dapt’s driveshaft loops are made out of two-inch wide, quarter-inch thick steel and are powder coated for corrosion resistance.
Recognizing that the 1993-2002 Camaro/Firebird and 1978-1993 Ford Mustang are some of the most popular drag cars among amateur racers, Trans Dapt made sure to have bolt-in solutions for these vehicles. The F-Body loop (Part# 4141) replaces the light duty factory crossmember, fits both automatic and 6-speed manual transmission models, and provides clearance for up to a 2.5-inch y-pipe. The Fox Body Mustang loop (Part# 9813) fits snug to the floorpan for maximum clearance and is predrilled for easy installation. For all other applications, the universal bolt-in driveshaft loop (Part# 4140) is adjustable to be compatible with just about any vehicle’s driveshaft height.
Trans Dapt driveshaft loops come with all hardware necessary for installation and meet all current (2013) NHRA regulations for safety equipment. For more information on Trans-Dapt’s driveshaft loops please call (562) 921-0404 or visit www.tdperformance.com.
