Powerflex Front Anti Roll Bar Bushes 21mm - Pack of 2 • PFF36-402-21

Powerflex PFF36-402-21 Front Anti Roll Bar Bushes 21mm - Position 2 - Pack of 2

Replacement Powerflex front anti roll bar bushes for Mazda MX-5 MK3 / MK3.5 / MK3.75 NC (2005-2015) models without the retractable hardtop and fitted with a 21mm front anti roll bar as listed in the compatibility table. This part is shown as position 2 on the Powerflex suspension bush diagram.

These polyurethane bushes support the front anti roll bar where it mounts to the chassis, helping reduce unwanted bar movement and maintain more consistent front suspension response during cornering. They are designed as aftermarket replacements for the original rubber components.

Two bushes are required per vehicle, with one fitted at each front anti roll bar chassis mounting point. This product is supplied as a pack of 2 bushes, providing the complete quantity required for one vehicle. This version is specifically sized for a 21mm anti roll bar.

Ageing original rubber anti roll bar bushes can harden, soften, split or wear over time. Typical symptoms can include knocking noises over uneven roads, excessive movement in the anti roll bar, reduced steering precision or a less controlled feel from the front suspension.

Fitment advice: This bush is specifically for Mazda MX-5 NC models without the retractable hardtop and using a 21mm front anti roll bar. Measuring the anti roll bar diameter at the bush mounting point is recommended where suspension parts have previously been changed or upgraded.

Other items to consider: When replacing the front anti roll bar bushes, inspect the front drop links, anti roll bar mounting brackets, related fasteners and remaining front suspension bushes for wear or corrosion.

Useful tools / consumables: Suitable vehicle lifting equipment, socket and spanner set, penetrating fluid, cleaning materials and the supplied Powerflex assembly lubricant where applicable.

Difficulty guide: DIY Difficulty: Easy to Moderate. Access is generally straightforward with the vehicle safely supported, although corrosion around the anti roll bar mounting bracket fasteners can make removal more difficult.
