                                GM “A” Body Rear Tubular Control Arms
Subframe Connectors
GLO900
For street or drag racing,
rear control arms are TIG
welded from 2" diam-
eter DOM (Drawn Over
Mandrel) tubing. Tubular units increase traction, improve straight line stability, and reduce wheel hop. Lower control arms have spherical aircraft bearings on the frame side and Del-A-Lum bushings on the rear end side. Upper control arms use high-misalignment spherical bearings for pinion angle adjustment. All control arms are sold in pairs with hardware and instructions.
Drag Racing Tires
Subframe con-
nectors prevent
chassis flex,
increase rigidity,
and reduce rattles and squeaks in unibody cars. Connectors also provide a mounting point for a roll bar or cage. Made of durable 1-5/8" O.D. x .125" wall DOM (Drawn Over Mandrel) tubing, connectors are finished in black powder coat, and include hardware and instructions.
