Product Overview
SuperPro 17mm Rear Sway Bar Bush – Toyota and Lexus Suspension Upgrade
The SuperPro 17mm Rear Sway Bar Bush SPF2817-17K is a premium polyurethane anti-roll bar mounting bush kit for selected Toyota and Lexus vehicles equipped with a compatible 17mm rear anti-roll bar.
Also known as rear anti-roll bar bushes or stabiliser bar mounting bushes, these components secure the rear anti-roll bar to the vehicle’s chassis or subframe while allowing the bar to rotate as the suspension moves.
Over time, original rubber bushes can deteriorate, compress or wear, allowing excessive movement of the bar. Replacing worn mounts with correctly sized SuperPro polyurethane bushes can help restore secure mounting, consistent suspension response and a more controlled driving feel.
Supplied as a pair, SPF2817-17K is designed for both rear anti-roll bar mounting positions.
Why Choose SuperPro 17mm Rear Sway Bar Bushes?
1. Premium Polyurethane Construction
SuperPro manufactures its performance suspension bushes using a proprietary engineering-grade polyurethane formulation.
The material is developed to provide durability while maintaining the controlled flexibility required for suspension operation.
Compared with worn original rubber bushes, correctly installed SuperPro replacements can help reduce unwanted anti-roll bar movement and restore more consistent suspension behaviour.
2. Precisely Sized for a 17mm Rear Anti-Roll Bar
The SPF2817-17K uses a 17mm internal diameter.
SuperPro also offers related bush designs for different anti-roll bar diameters, including 14mm, 15mm, 18mm and 19mm versions.
Selecting the correct size is essential. A bush with an oversized opening may permit unwanted movement, while an incorrectly undersized bush can cause excessive friction or installation problems.
Measure the rear anti-roll bar where the bush sits, rather than relying solely on the vehicle model or advertised bar size.
3. Designed for Improved Suspension Control
The rear anti-roll bar helps manage body roll by resisting differences in suspension movement between the left and right rear wheels.
Its mounting bushes provide a secure connection between the bar and the vehicle.
When the bushes become worn, the bar may move excessively in its mounts, contributing to noise and inconsistent suspension response.
SuperPro polyurethane bushes are designed to maintain secure mounting and consistent operation.
They do not increase the anti-roll bar’s diameter or fundamentally change its torsional stiffness.
4. Resistant to Common Automotive Contaminants
SuperPro states its polyurethane formulation is resistant to environmental exposure, including water, oils, coolant and extreme temperatures.
This makes the material suitable for demanding conditions encountered during everyday UK driving.
The bushes still require correct installation, secure brackets and periodic suspension inspection.
5. Complete Rear-Axle Bush Kit
Each SPF2817-17K kit contains two polyurethane bushes, enough for the vehicle’s two rear anti-roll bar chassis-mounting positions.
Only one kit is normally required per compatible vehicle.
Anti-roll bar drop links, mounting brackets and replacement anti-roll bars are not listed as included components.
6. Australian Suspension Engineering
SuperPro has more than four decades of experience developing performance polyurethane suspension components.
Its bushes are designed, engineered and manufactured in Australia, with product-specific designs developed for a wide range of road and performance vehicles.
The SPF2817-17K is backed by SuperPro’s lifetime warranty, subject to the manufacturer’s warranty terms.

These dimensions help distinguish SPF2817-17K from other SuperPro anti-roll bar bushes.
Toyota and Lexus Vehicle Compatibility
SuperPro identifies SPF2817-17K for selected Toyota and Lexus rear anti-roll bar applications.
Relevant vehicle families found in supplier application information include selected Lexus GS and IS models, Toyota Altezza and Toyota Aristo variants.
However, not every version uses a 17mm rear bar.
Bar diameter can vary by chassis code, original suspension specification and previous modifications.
Before purchasing, confirm:
- Rear anti-roll bar diameter of 17mm at the mounting point
- Correct rear-axle mounting position
- Original bracket and bush dimensions
- Vehicle chassis and suspension configuration
The manufacturer also lists other sizes within the SPF2817 design family, so diameter should never be assumed from the model name alone.
SuperPro Polyurethane vs Standard Rubber Bushes
Original rubber bushes are often designed to prioritise comfort, vibration isolation and cost.
SuperPro polyurethane bushes are developed to offer consistent mounting characteristics and durability in demanding suspension applications.
When replacing damaged rubber bushes, polyurethane can help restore the intended operation of the anti-roll bar.
For a vehicle driven on UK roads, it is important to choose an appropriate bush design rather than assuming the stiffest available material will always produce better handling.
Anti-Roll Bar Bushes vs Anti-Roll Bar Upgrades
Replacing worn anti-roll bar bushes and fitting a thicker anti-roll bar are different modifications.
Replacement bushes primarily restore or maintain correct bar mounting.
A thicker or adjustable anti-roll bar changes suspension roll stiffness and can affect the car’s handling balance.
For a detailed comparison, read our Anti-Roll Bar vs Strut Brace UK Guide.
The guide also explains why worn mounting bushes and drop links should be addressed before making larger handling changes.
Installation and Wheel Alignment
Professional installation is recommended where access to the rear anti-roll bar mounting brackets is difficult.
Before fitting, inspect the anti-roll bar for corrosion or damage, clean the mounting positions and confirm the new bushes sit correctly inside the brackets.
Follow the latest SuperPro fitting instructions, including any specified assembly lubricant.
The manufacturer’s product page recommends a rear wheel alignment check after fitting.
Read our Wheel Alignment Guide for advice on camber, toe and suspension geometry.
