Since the mid-'60s, the term weight transfer has been commonly used by drag racers to describe the rear suspension's ability to deliver the vehicle's weight over the rear wheels. For inherently rearend-light Tri-Five pickups, the TCI parallel four-link suspension kit is a good solution to potentially bad traction problems encountered during all driving conditions. This bolt-in kit enables do-it-yourself Tri-Five owners to perform a successful install at home. The only welding required for the basic kit is to attach the link pickup point brackets to the rear axle (differential). For Tri-Five owners desiring a conversion to an optional Currie 9-inch rearend, no welding is required, period.
