Thank you. You have rated this product.

Prothane Urethane Bushing Kit, Black 88A Durometer. One of the components of your car that suffers silently with age is the rubber in the suspension bushings. Over time, they break down and allow more movement of the control arms. This makes your handling sloppy and makes the car feel old. This Prothane polyurethane bushing set replaces just about every piece of rubber in the suspension. Poly bushings move differently than rubber ones, allowing less deflection and no pre-loading. This means more precise and consistent handling, with a slight increase in sharp impacts. Includes new bushings for the control arms and differential mounts. It also includes new bushings for stock sway bars and end links. Installation is not trivial and will require a press. If you're looking to replace your old, tired suspension bushings, this complete urethane kit from Prothane offers an ideal solution.

Supplied with over 30+ different components, this comprehensive kit includes the following items: front and rear sway bar bushings (for use on the stock sway bars only), front sway bar retaining clamps, front and rear endlink bushings, rear differential mounting bushings, and front and rear upper and lower control arms. Also included are replacement sleeves where required, and lubricating grease packets. All bushings are black-colored and sleeves are yellow zinc plated steel.

The sway bar bushings included in the kit are intended for use with the Mazda stock sway bars only.

Bushings fit 1990-2005, although the sway bar bushings are for the 1990-97 end links. The front sway bar bushings fit a 19mm front bar.

This Prothane "Master Kit" includes:
4x Front upper control arm
2x Front lower control arm, forward
2x Front lower control arm, aft
4x Rear lower inner control arm
4x Rear upper inner control arm
2x Rear upper outer control arm
4x Rear lower outer control arm
16x end link bushings
2x Front sway bar bushings 19mm
2x Rear sway bar bushings 12mm
2x Differential mount bushings

APPLICATION NOTES: Kit works for all 1990-2005 Mazda Miata, except the sway bar bushings are for the 1990-97 end links (not later 1999 to 2005). Also, the front sway bar bushings fit a 19mm front bar (not the 20mm R package bar), and 12mm rear bar (94-97 have 11mm rear sway bar, included 12.4mm bushings work but not as tight).

Sean's Installation Notes:

Having gone through this process from start to finish, I must stress the importance of a shop press. Due to the double wishbone design on our Miatas, there are A LOT of bushings to remove. Using other methods, torch or DIY tools, will add to an already time consuming project. Highly recommened to find a friend with a press OR purchase a Harbor Freight shop presses. Harbor Freight presses are an excellent value and can be purchased with Habor Freight's frequent 20% off coupons.

I just installed the Borla exhaust on the MX5. Sweeeeeeet! Thanks, Andy


Thanks for making this work and providing great customer service! I had a full weekend with the install, but man was it worth it. The flywheel was such a good choice. I can't believe how much easier rev-matching down shifts are. The ACT is surprisingly easy to live with, even with the engagement point very low. I'll tackle that when it stops raining. Thanks again for making this happen this weekend.
