The PRO OTR was created for use only with MAX limitbreak knuckles that use ackerman adjusters, which utilize a straight through M14 bolt connection. These are shorter length than our Limit Break version outer tie rods. Similar in length to OEM S14 outer tie rods. These are replacements for the outer tie rods included in the Z33 and GT86 angle kits. Can be used when pairing our Corvette and S-chassis knuckles with stock length control arms. ~CNC steel threaded sleeve ~High Misalignment spherical bearings ~ Grade 12.9 M14 bolts with 5mm bump steer adj. spacers **Not for OEM tapered knuckle receivers. Tapered tie rods sold separately. Check out the chart when combining LimitBreak outer tie rod (or shorter OTR) with our 3 inner tie rod lengths and rack to inner tie rod offsetters to determine proper length.
