Genuine Mazda Front Anti-Roll Bar D-Bush Mounting Bracket • F151-34-155

Genuine Mazda F151-34-155 Front Anti-Roll Bar D-Bush Mounting Bracket

Replacement Genuine Mazda front anti-roll bar bush mounting bracket for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 NC models, including fabric soft-top and Power Retractable Hard Top vehicles.

This pressed-metal bracket fits over the rubber front anti-roll bar D-bush and bolts to the front crossmember. It retains the bush securely around the anti-roll bar while allowing the bar to twist as the suspension operates.

The front anti-roll bar connects the left and right sides of the front suspension. As the vehicle corners, the bar twists to help limit body roll and maintain more controlled suspension movement.

A corroded, bent or damaged bracket may fail to clamp the rubber bush correctly. This can allow movement between the anti-roll bar, bush and crossmember, potentially contributing to knocking, rattling or reduced suspension precision.

There are two brackets fitted per vehicle, one for each front anti-roll bar mounting bush. This listing supplies one Genuine Mazda bracket, so select a quantity of two when replacing both sides.

Important bush distinction: The same bracket is used with the applicable front anti-roll bar bush, but Mazda specifies different rubber D-bushes for fabric soft-top and Power Retractable Hard Top — PRHT — models. Select the correct bush separately according to the vehicle body style.

Possible reasons for replacement:

• Heavy surface corrosion or metal loss

• Cracking around the mounting holes
• Damaged mounting-hole faces
• Bracket no longer clamping the bush evenly
• Restoration of heavily corroded suspension hardware

Fitment advice: This bracket is used on both sides of the MX-5 NC front anti-roll bar. Confirm that the original front crossmember and anti-roll bar arrangement remain fitted, particularly where an aftermarket anti-roll bar or modified mounting system has been installed.

Other items to consider: Inspect both front anti-roll bar bushes, the bracket on the opposite side, all four bracket bolts, the anti-roll bar surface and both front drop links. Replace any bush that is split, compressed, hardened or worn internally.

Useful tools / consumables: Suitable socket and ratchet set, extension bars, penetrating fluid, wire brush, calibrated torque wrench, vehicle lift or axle stands and suitable corrosion protection for surrounding exposed metal where required.

Difficulty guide: DIY Difficulty: Moderate. The brackets are mounted beneath the front of the vehicle, and access may be restricted by surrounding components. The vehicle must be raised and supported safely before work begins.

Why Genuine Mazda? Genuine Mazda anti-roll bar brackets are formed to match the original D-bush profile, bolt spacing and front-crossmember mounting arrangement. Correct bracket dimensions help clamp the bush evenly without distorting it or allowing unwanted anti-roll bar movement.

What’s in the box: One Genuine Mazda front anti-roll bar D-bush mounting bracket, part number F151-34-155. Rubber bush and mounting bolts are not included.

Installation notes: Raise and support the vehicle safely. Support the anti-roll bar as necessary before removing the bracket bolts. Clean the crossmember mounting face and inspect the bolt threads, bracket and rubber bush. Position the correct body-style bush around the anti-roll bar, fit the bracket over it and start both bolts by hand. Tighten the bolts progressively and evenly to the applicable Mazda workshop specification, ensuring that the bush and bracket remain correctly seated.
