Our racing trailing arms start life as new OEM stock arms which we sandblast, reinforce with a continuous perimeter weld and add a. Your options are the stock rubber bushings which deflect with the arc, or poly bushings which are forced to deflect when put into a bind, and quickly wear an oblong hole. For that reason, it's not possible to run solid steel bushings in your trailing arms. The trailing arm front bushing has to accommodate movement up and down in an arc. These control arms are made to exact specifications and use 1020 DOM tubing. All other bushings manage movement about an axis on a fixed plane. Our brand new 1963-82 Chevy Corvette Tubular upper control arms are designed for the performance enthusiast. The trailing arm front bushing is the only bushing on the car that has to accommodate movement about an axis with a variable plane. Install them and forget them, as they will work for the typical 2800 lb vintage Corvette club racecar.ĭuntov HD Trailing Arm with Spherical Bearing We have tested and have run these shocks right out of the box. This looks like a street car shock, but it is definitely a proper vintage Corvette custom racing shock. We extensively and thoroughly test shocks and offer three options for the vintage Corvette racer. Testing to us means not only plotting the shock performance on a shock dyno, but also testing the shocks on the track during a dedicated and controlled test session. Most vintage racers never test their shocks, and therefore don't get much benefit from adjustable shocks.

This publication is 40 years old, but the information is still valid and obviously period correct. Designed for use with Stock lower control arms Improves range of motion & eliminates binding Strong design prevents deformation and failure Positive transfer of motion through sway bar OEM high-performance quality 1.125 O.D. If you are building your own C2 or C3 racecar, it might help to use GM's guide to modifying the C2/C3 Corvette chassis for racing. Our cars have arguably the stiffest chassis ever built for a C3 Corvette. Replaces all 16 control arm bushings and includes new 4130 chromoly trunnions. Reduction in deflection creates a more consistent, predictable handling. Even if he is only half right, that still says a lot about the importance of chassis stiffness. This bushing designed to eliminates control arm shift, common with factory bushings. The majority of the other 90% is chassis stiffness". Watch the video above for more information.According to Corvette chief engineer Tadge Juechter, "dampers, springs, and bushings account for only the last 10 percent of handling. Part # CTA-42AP uses polyurethane bushings G-Plus control arms are offered two ways. New alignment specifications are included. The arms are shipped assembled with billet cross shafts, ball joints, Del-a-lum bushings (standard), and bump stops.ĥ. The new bump stop location allows for a limiter, which can be installed for drag race applications.Ĥ. A bump stop is installed on the control arm eliminating the stock one on the frame. The combination keeps the tire flatter on the pavement.ģ. The arms have additional caster built into the them and a improved camber curve. G-PLUS arms can use stock, 2 inch drop spindles, and ATS spindles.Ģ. 1964-72 Chevelle, El Camino, Malibu, Monte Carlo, Skylark, Special, Grand Sport, Sport Wagon, F-85, Cutlass, 442, GTO, Lemans, T37, Tempestġ. ![]() Tubular Upper Control Arms with Del-A-Lum Bushings Part #CTA-42A
