      Description

      What it solves

      Revitalize the handling and stance of your classic muscle car with the UMI 275153 Tubular Front A-Arm Kit. This complete front suspension package replaces your weak, flex-prone factory stamped steel arms with high-strength DOM tubing components designed to deliver modern, responsive geometry. The uppers feature a relocated ball joint pad to increase positive caster, while the lowers correct the camber curve for lowered ride heights. Combined, they drastically improve steering feel, straight-line stability, and cornering grip without requiring massive stacks of alignment shims.

      Engineered specifically for the 1967–1969 Camaro, Firebird, and 1968–1974 Nova, this comprehensive kit drops right in with factory spindles and supports factory springs, lowering springs, or coilovers. Each arm ships fully assembled with premium standard-length ball joints, UMI-built Delrin upper bushings, and greaseable polyurethane lower bushings. Built with pride, track-tested, and manufactured 100% in the USA at UMI’s Philipsburg, PA facility, this kit gives your vintage chassis the precision and strength it deserves.

      ✓
      Lowered camber correction: The 2751 lower arms optimize ball joint angles to correct camber curves on stock to 2-inch lowered vehicles, ensuring a flat tire contact patch.
      ✓
      DOM steel construction: Fabricated in-house from 1.25-inch upper and 1.5-inch lower .120 wall DOM tubing for exceptional strength and improved exhaust header clearance.
      ✓
      Premium pre-installed bushings: Features CNC-machined zero-deflection Delrin bushings in the uppers and fluted, greaseable polyurethane bushings in the lowers for tight, predictable articulation.
      ✓
      Universal first-gen fitment: Lower arms feature steering stop pads welded both fore and aft, plus repositionable polyurethane bump stops to fit all variations of the early subframes.
      ✓
      Ready to bolt on: Ships fully assembled with standard-height premium ball joints and heavy-duty rod end style sway bar end links, saving you hours of press work.
      ✓
      Tough powder-coated finish: Protects your investment from harsh road elements and corrosion while providing a clean, professional look in your wheel wells.

      1.5" DOM tubing construction

      Built from .120 wall high-strength steel tubing that is CNC-machined and rotary draw bent for unmatched durability.

      Greaseable bushings:

      Polyurethane (PN 2751) or Delrin (PN 2752) pre-installed and fluted for smooth, quiet operation, providing improved steering response over deflected factory rubber.

      Optimized handling geometry

      Installation Summary

      Before you buy

      Overview & Difficulty: Moderate DIY install requiring a floor jack, jack stands, ball joint separator, and basic hand tools; approximately 5–8 hours for the complete system. Install new lower arms (leaving frame bolts loose until ride height) and upper arms (noting cross-shaft orientation for baseline camber). Reassemble with factory spindles, springs, and shocks.

      What’s Included:
      • Tubular upper A-arm assemblies (Driver & Passenger) ×2
      • Tubular lower A-arm assemblies (Driver & Passenger) ×2
      • Pre-installed premium standard-height ball joints ×4
      • Repositionable polyurethane lower bump stops ×2
      • Fixed polyurethane upper bump stops ×2
      • Rod end style sway bar end links ×2

      Relocated ball joint pad:

      1.25-inch DOM tubing

      Formed on a programmable rotary draw bender for precise, repeatable tolerances, high strength, and much better header clearance than factory stamped arms.

      Fluted Delrin bushings

      CNC-machined in-house by UMI, these greaseable bushings provide zero deflection during hard cornering for crisp, predictable handling over rubber.

      4140 chromoly cross shafts

      CNC-machined for incredible strength and zinc-plated for maximum corrosion resistance, ensuring years of trouble-free performance.

      Reversible camber baselines

      Cross shafts can be installed with the shallow side to the frame for positive camber or the deeper side for aggressive negative camber.

      Premium ball joints

      Ships fully assembled with standard-height premium ball joints (PN 2753) or 1/2" taller ball joints (PN 2753-1) and polyurethane bump stops so you can bolt them right up out of the box.

      Product FAQ

      Quick answers
      What vehicles does the 275153 A-arm kit fit?
      This complete kit is designed for the 1967–1969 Camaro and Firebird, as well as the 1968–1974 Chevy Nova. It is not compatible with factory front drum brakes.
      Does this kit include both upper and lower control arms?
      Yes. The 275153 package includes both the 2753 tubular upper A-arms and the 2751 tubular lower A-arms for a complete front suspension overhaul.
      How does this kit improve my vehicle's alignment?
      The upper arms feature a relocated ball joint pad to increase positive caster natively, while the lower arms correct the camber curve on lowered vehicles to keep the tire flat.
      What type of bushings come with this kit?
      The upper control arms feature UMI-built, zero-deflection Delrin bushings, while the lower control arms come with fluted, greaseable polyurethane bushings.
      Do I need to buy ball joints separately?
      No. All four control arms ship fully assembled with premium standard-height ball joints already pressed in and ready to go.
      What springs can I use with these control arms?
      The lower arms are designed to work seamlessly with factory coil springs, aftermarket lowering springs, or coilover kits.
      Will these control arms give me better header clearance?
      Yes. The upper arms are CNC-bent from 1.25-inch DOM tubing using a programmable bender to offer significantly improved header clearance over bulky factory stamped arms.
      Does the kit include installation hardware?
      Frame mounting hardware is not included. You can re-use your factory hardware, or purchase UMI upper & lower a-arm hardware kit 4002.
      Can I use these with drop spindles?
      Yes. The lower arms can be paired with a 2-inch drop spindle (like part 910-3500B) to achieve an aggressive stance while keeping camber near zero.
      Where is this suspension kit manufactured?
      The entire 275153 front A-arm kit is designed, track-tested, and manufactured 100% in the USA at UMI Performance’s facility in Philipsburg, Pennsylvania.
