Product Description:
Hawks Motorsports is proud to offer our clients this : 1967-1969 Chevrolet Camaro and Pontiac Firebird Front Lower Control Arm Grade 8 Hardware Kit from UMI Performance.
UMI Performance #4001 provides the high-strength fasteners needed to attach both front lower control arms to the subframe of applicable 1967, 1968, and 1969 GM F-body models.
The kit includes four 1/2-inch SAE Grade 8 bolts, four flat washers, and four nylon-insert locking nuts. All supplied components feature a zinc coating that helps protect the hardware against corrosion while providing a clean, finished appearance.
Four bolts provide the two pivot fasteners required for each front lower control arm. UMI-4001 can be used with compatible UMI Performance lower A-arms, factory-style lower control arms, and other aftermarket control arms designed around the original 1/2-inch mounting dimensions.
This complete hardware package is an excellent choice when replacing original lower-control-arm fasteners that are worn, rusted, damaged, seized, or missing. It is suitable for factory restorations, front-suspension rebuilds, performance-street vehicles, Pro-Touring builds, autocross cars, road-course vehicles, and drag-racing applications.

Important Fitment Notes
- UMI-4001 is used at the front lower-control-arm pivot locations.
- One kit supplies the mounting hardware for both front lower control arms.
- Each lower control arm uses two pivot bolts.
- The supplied bolts are 1/2-inch SAE Grade 8 fasteners.
- Verify that the control-arm bushing sleeves and subframe mounting holes accept the correct 1/2-inch fasteners.
- Compatible with applicable factory and aftermarket front lower control arms.
- Confirm dimensions when installing custom-fabricated, modified, or non-standard control arms.
- Inspect the subframe mounting brackets and holes for rust, cracking, distortion, or elongation.
- Damaged or elongated mounting holes must be properly repaired before installation.
- Previous collision repairs or subframe modifications may affect alignment and fitment.
- This kit does not include hardware for the front upper control arms.
- This kit does not include ball-joint, shock, coil-spring, steering, or sway-bar hardware.
- Compatibility with disc- or drum-brake vehicles depends on the lower control arms being installed. UMI #4001 itself is the pivot-hardware package.
- UMI #2751 and #2752 lower A-arms do not fit factory drum-brake applications, but that restriction applies to those control arms rather than the UMI-4001 fasteners.
- UMI catalogs #4001 for additional GM platforms, but this Hawks Motorsports listing is specifically written for 1967-1969 Camaro and Firebird applications.
6. INSTALLATION NOTES
- Review the vehicle service manual and control-arm manufacturer’s instructions before installation.
- Confirm that the vehicle and lower control arms require 1/2-inch mounting fasteners.
- Park the vehicle on a solid, level surface.
- Safely raise and support the vehicle using properly rated lifting equipment.
- Never work beneath a vehicle supported only by a hydraulic jack.
- Front coil springs store substantial energy and can cause serious injury if improperly handled.
- Safely contain and support the front coil spring before removing a lower control arm.
- Support the lower control arm and steering assembly during disassembly.
- Replacing one lower control arm at a time can help preserve component orientation and reference points.
- Record the direction and position of the original fasteners before removal.
- Inspect the subframe mounting brackets for corrosion, cracking, distortion, or elongated holes.
- Inspect the lower-control-arm bushing sleeves before installing the new hardware.
- Do not force a bolt through a misaligned bushing sleeve or subframe bracket.
- Correct the component alignment before inserting the fasteners.
- Verify that the bolt shanks pass completely through the brackets and bushing sleeves.
- Confirm that each nylon locking nut achieves full thread engagement.
- Do not use damaged fasteners or components with contaminated or damaged threads.
- Install the hardware loosely until the lower control arm is correctly positioned.
- Follow the vehicle service manual or control-arm manufacturer’s specified torque procedure.
- UMI advises performing final tightening of its polyurethane-bushed lower A-arms with the suspension positioned at normal ride height.
- Tightening rubber or polyurethane control-arm pivots with the suspension hanging may create unwanted bushing preload.
- Follow the manufacturer’s instructions when installing Delrin, bearing, or solid-pivot control arms.
- UMI does not publish one universal torque specification for UMI-4001 that applies to every factory and aftermarket control arm.
- Verify that the lower control arms move through their intended range without binding.
- Check clearance around the coil springs, shocks, sway bar, steering components, brake hoses, wheels, and tires.
- Complete a professional front-end alignment after replacing the lower control arms.
- Reinspect the mounting hardware following the initial road test.
- Periodically inspect the fasteners and mounting points as part of normal suspension maintenance.
