Pair of extended front upper control arms for C7 Corvette. These are extended 1.25" longer than stock, so they are meant to be paired with extended lower arms as well. Compatible with OEM C7 knuckles. Not compatible with our Forged Super Angle Knuckles. When using our forged super angle knuckles, use our C6 front upper arms, sold separately. Thinner profile than stock arms for more steering angle clearance. Enough inside clearance for coilovers and for our airbag over damper kit. Adjustable steering angle stops prevent tires from contacting the arms and are specially modeled in CAD to prevent bump stop steering upon contact throughout full suspension travel. Made of Japanese DOM steel tube, 3.5mm wall. Hand Tig welded and 3 stage copper paint. PTFE lined maintenance free, low torque spherical bearings. CrMo bearing side spacers. Compatible with OEM and aftermarket knuckle ball joint tapers. **Approx 1.25" longer than stock, so you will need extended lower arms to achieve proper camber.
