GM MID-SIZED CAMS (PR) GM’s late-model mid-sized 4WD’s have very little clearance to adjust the camber and caster with the OE adjusting cams. These specially designed adjusters replace the OE adjusters, and feature a 3/8” square drive hole, allowing fast and easy “on-the-vehicle” adjustments with any standard breaker bar. The unique design saves time by installing onto the OE bolt – no need to replace the bolt – and allows for quick future adjustments.

Front Adjustment range: Camber ±1.50°/Caster ±1.50° Required: 1 per wheel (2 Cams in kit) APPLICATIONS Chevrolet: 2004 - 12 Colorado GMC: 2004 - 12 Canyon Hummer: 2006 - 10 H3, H3T Isuzu: 2006 - 08 i350/i370
