      Description

      What it solves

      Upgrade your classic F-body's rear suspension with the UMI Performance 272829 Outboard Double Shear Rear Shock Mount Kit. This system converts the weak factory upper single stud mount into a rigid double-shear configuration, eliminating energy-wasting flex. The lower mounts are replaced by heavy-duty outboard leaf spring plates CNC-formed from 1/4-inch high-strength steel, preventing twisting under hard cornering or launch.

      Engineered for 1967–1969 Camaro and Firebird models, this bolt-on kit includes upper mounts (2728DR and 2728PA), lower leaf plates (2730), and premium hardware. It is optimized for Viking poly bushing or bearing-end shocks and includes poly bushing sleeves and aluminum spacers. Track-tested at UMI Motorsports Park, this suspension upgrade is built 100% in the USA for ultimate street and competition durability.

      Installation Summary

      Before you buy

      Overview & Difficulty: This moderate DIY installation takes 2 to 4 hours to complete using basic garage tools, including jack stands, sockets, wrenches, an Allen wrench, and a torque wrench. The process involves lifting the rear chassis to let the suspension fully droop, removing the wheels, and supporting the rear axle. You will swap the factory leaf plates with the heavy-duty outboard plates, torquing the U-bolts to 55 ft-lbs in an X-pattern. Replace the upper mount (torque to 260 in-lbs), grease and install the poly sleeves, then secure the shocks, torquing the upper bolt to 50 ft-lbs.

      What’s Included:
      • Double shear driver's side upper rear shock mount (2728DR) ×1
      • Double shear passenger side upper rear shock mount (2728PA) ×1
      • Outboard lower leaf spring plates (2730) ×2
      • Zinc-plated alloy steel socket head screws, 1/2"-13 × 2-1/4" (1000206) ×4
      • Grade 8 thin nylock nuts, 1/2"-13 (1000110) ×4
      • SAE washers, 1/2" (1000015) ×4
