Torque Monsta Buying Guide · Detailed guide
Suspension Bushes & Mounts
Understand rubber, polyurethane and spherical mounting options, and where extra precision may introduce noise or maintenance.
Measure first
What to measure or record
Identify the exact arm/location and measure the bush outer diameter, inner sleeve/bolt diameter and installed width when the catalogue requires it. Check whether the original shell is retained. Record current symptoms and alignment movement rather than assuming every bush needs the hardest material.
Decision guide
Choose by intended use
Comfort road
OE-quality rubber for isolation and low maintenance.
Fast road
Moderate-stiffness polyurethane in key geometry locations, with correct lubricant where specified.
Track
Higher-stiffness polyurethane or spherical joints where precision justifies noise and inspection.
Restoration
Replace failed items systematically and torque bonded rubber bushes at normal ride height.
Understand what you are buying
Key terms explained simply
Rubber
Quiet and compliant; bonded types are normally tightened at ride height.
Polyurethane
More location, with stiffness and lubrication varying by design.
Spherical bearing
Precise but noisy and inspection-intensive.
Shore hardness
Material hardness, not a complete prediction of comfort.
Offset bush
Changes geometry and needs correct orientation and alignment.
Why bushes matter
Bushes locate suspension components while controlling noise and movement. Worn parts can cause vague handling, uneven tyre wear, knocks and unstable alignment.
Material choice
Rubber generally gives the best isolation. Polyurethane can improve location and durability but may add noise or require lubrication. Spherical joints provide precision for competition use with greater inspection and maintenance needs.
Choose the right locations
Replacing every bush with the hardest option can make a road car unpleasant. Prioritise failed bushes and the positions that most influence geometry, then match stiffness to intended use.
Installation
Some bushes need shells removed or reused, a defined orientation or tightening at normal ride height. Alignment should be checked after disturbing suspension mounting points.
Straight answers
Frequently asked buyer questions
Replace every bush?
Not automatically. Inspect all locations and prioritise failed or geometry-critical parts. Maximum stiffness everywhere rarely suits a road car.
Will polyurethane squeak?
It can if a lubricated design is dry, contaminated or misaligned. Use only the supplied lubricant and method.
Why tighten rubber at ride height?
Bonded rubber twists through travel. Tightening at droop preloads it at normal height and can cause failure.
Are harder bushes better?
They can sharpen response but add noise and may reduce rough-road grip. Match each position to the use.
Do I need alignment?
Yes after disturbing geometry-controlling arms or mounts.
