The aFe Control Adjustable End Links Kit (part 442-721001-L) is a matched front and rear set of sway bar end links for the 3.0L six-cylinder GR Supra (A90). Each link uses a billet 6061-T6 aluminum adjuster, CNC-machined and anodized blue, with a PTFE-lined Aurora rod end on each side. The manufacturer says the rods are threaded in opposite directions so the length can be dialed in on the car without disconnecting them. Stock links offer no adjustment, so a lowered or coilover-equipped car can end up with sway bar preload that changes how it turns left versus right. Owners on user forums commonly point to this as the reason to upgrade, especially when corner balancing. Searches for "A90 Supra adjustable sway bar end links," "GR Supra preload adjustment," and "2020 2021 Supra 3.0 end link kit" lead to this part.
The kit is listed for the 2020 to 2021 GR Supra 3.0L, and the manufacturer's application data also covers the wider A90 range, so buyers should confirm their model year and trim before ordering. The manufacturer lists a front adjustment range of 14.875 to 16.125 inches and a rear range of 4.375 to 5.625 inches, with 1144 StressProof studs and joint articulation designed to exceed factory range to reduce binding. The manufacturer also states the kit requires no modifications and does not need a CARB EO number. Because the front and rear links are sold together, you can zero preload on both axles in one pass.
Yes. The manufacturer describes right-hand and left-hand rod ends that allow on-car length adjustment without removing the links. Owners on user forums recommend setting them with the car at normal ride height on a level surface so the bar sits with no preload.
No. The manufacturer states this product does not require a CARB EO number.
The manufacturer says these are a direct-fit bolt-in with no modifications, and the on-car adjusters let you set length after installation. Plan on jacking and supporting the car safely, and take photos of the sway bar clocking and link orientation before removing the stock links. Owners on user forums have reported problems when a front aFe sway bar and link set was installed without correct clocking and torque, causing tie rod contact and broken link joints, so confirm bar position and clearance at full lock. Lowering can also change link angle and bar clearance, so set final ride height before finalizing link length. Torque specifications were not confirmed in this research, so use the manufacturer's install instructions and re-check hardware after the first track session.
