R35 GT-R Mishimoto 2.25" Stainless Steel T-Bolt Clamps for Use with 2.0" Couplers

These clamps are smooth on the inside and will not bite into silicone like worm gear clamps. Clamping ability is over 20 times greater than worm gear clamps. Bolt is easy to tighten since it is out away from the clamping surface.
