Strut Mount Manufacturer - Suspension Strut Top Mounts with Bearing Assembly
ARPL manufactures rubber-to-metal bonded strut mounts for MacPherson and modified strut suspension systems. Our strut top mounts connect the suspension strut to the vehicle body, isolating road vibration and noise while supporting spring loads and enabling steering rotation through integrated thrust bearings. ISO 9001:2015 certified manufacturing at IMT Manesar, Haryana.
Strut Mount Types
Suspension Strut Mounts for Automotive OEMs
Strut mounts sit at the top of the MacPherson strut assembly, forming the critical connection between the suspension and the vehicle body. They perform multiple functions simultaneously: absorbing vertical shock and road vibration, isolating noise transmission to the passenger compartment, allowing angular changes as the suspension travels, and in front suspensions, acting as a steering pivot through an integrated thrust bearing that enables smooth steering rotation.
ARPL manufactures strut mounts using chemical rubber-to-metal bonding with natural rubber (NR) compounds optimized for high resilience, low compression set, and long fatigue life under the demanding conditions of Indian and global road surfaces. Our facility at IMT Manesar, Haryana serves automotive OEMs and Tier-1 suppliers across Delhi NCR, Pune, Chennai, and globally.
Strut Mount Specifications & Capabilities
ARPL designs and manufactures strut mounts to meet OEM static and dynamic performance requirements, with in-house testing for vertical compression, torsional fatigue, and adhesion quality.
Key Performance Parameters
- Rubber compound: Natural Rubber (NR) — primary compound for highest resilience, dynamic fatigue resistance, and vibration isolation. EPDM and CR available for special requirements.
- Hardness: 40 to 65 Shore A — tuned for the balance between vibration isolation (softer) and load support (firmer) per vehicle platform
- Temperature range: -40°C to +100°C — covers all climatic conditions from extreme cold to engine bay heat
- Vertical load capacity: up to 1000 kg per mount — supports spring loads from hatchbacks to SUVs and LCVs
- Bearing: Thrust ball bearing / needle roller — enables low-friction steering rotation in front MacPherson strut applications
- Metal: Mild steel, zinc/phosphate plated — corrosion-protected for 10+ year vehicle life including salt-spray environments
- Bond strength: Rubber tear before bond failure — "R" failure mode confirmed by destructive testing on every lot
Manufacturing Process
- Metal inserts — CNC machined or stamped steel parts, grit-blasted, phosphate-coated, and primed for bonding
- Rubber molding — compression or transfer molding with controlled cure for consistent hardness and bond quality
- Bearing assembly — thrust bearings press-fitted or integrated into the mount housing with sealed grease lubrication
- Testing — vertical static compression, torsional fatigue, adhesion testing, hardness, and dimensional inspection
Strut Mount Compound Comparison
| Compound | Temp. Range | Resilience | Fatigue Life | Weather | Best For |
|---|---|---|---|---|---|
| NR | -40 to +80°C | Excellent | Excellent | Fair | Standard passenger cars, SUVs (most common) |
| EPDM | -50 to +150°C | Good | Good | Excellent | Extended weather/ozone exposure applications |
| CR | -35 to +120°C | Good | Good | Good | Oil-exposed environments, commercial vehicles |
Strut Mount Applications
ARPL's strut mounts serve the full range of vehicles using MacPherson and modified strut suspension systems, from compact hatchbacks to heavy-duty SUVs and light commercial vehicles.
Passenger Cars & Hatchbacks
Front strut mounts with integrated thrust bearing for steering pivot function, and rear strut mounts for non-steering rear suspensions. Tuned for ride comfort and NVH refinement on standard road conditions. Supplied for popular Indian and global vehicle platforms.
SUVs & Crossovers
Heavy-duty strut mounts with higher load capacity for heavier spring rates and larger wheel travel. Designed for rough road durability including potholes, speed breakers, and off-road use common on Indian roads. Higher hardness compounds for increased load support.
Light Commercial Vehicles (LCVs)
Reinforced strut mounts for pickup trucks and light commercial vehicles with variable payload conditions. Designed for extended fatigue life under higher loads and continuous commercial use.
Aftermarket & Replacement
OE-quality replacement strut mounts for the automotive aftermarket, manufactured to OEM specifications with the same materials and bonding processes as original equipment parts.
Global Export Markets
ARPL exports strut mounts from Manesar, Haryana to OEMs and Tier-1 suppliers in the USA, Germany, UK, France, Italy, Japan, South Korea, Taiwan, UAE, Saudi Arabia, Turkey, Canada, Mexico, and Sweden.

Frequently Asked Questions
Find answers to common questions about strut mounts
A strut mount is a rubber-to-metal bonded component that connects the top of a MacPherson suspension strut to the vehicle body. It performs four critical functions: absorbing vertical road shock and vibration, isolating suspension noise from the passenger cabin, allowing angular changes as the suspension compresses and rebounds, and in front suspensions, acting as a steering pivot through an integrated thrust bearing that enables steering rotation.
Yes. ARPL manufactures strut mounts for automotive OEMs and Tier-1 suppliers at our ISO 9001:2015 certified facility in IMT Manesar, Gurugram, Haryana. We supply front and rear strut mounts for passenger cars, SUVs, crossovers, and light commercial vehicles, serving customers across Delhi NCR, Pune, Chennai, Bengaluru, and globally.
Front strut mounts include an integrated thrust bearing (ball or needle roller) that allows the strut to rotate with steering input, since the front MacPherson strut acts as a steering pivot. Rear strut mounts do not require a bearing as rear suspensions typically do not steer. Both types use rubber-to-metal bonding for vibration isolation and shock absorption.
ARPL primarily uses Natural Rubber (NR) for strut mounts, which provides the best combination of resilience, dynamic fatigue life, and vibration isolation for suspension applications. NR is the standard OEM material for strut mounts worldwide. EPDM and Neoprene (CR) are available for applications requiring enhanced weather resistance or oil resistance.
ARPL strut mounts support vertical loads up to 1000 kg per mount, covering the full range from compact hatchbacks through mid-size sedans to heavy-duty SUVs and light commercial vehicles. Load capacity is determined by the rubber compound, geometry, and metal insert design, all customized per OEM vehicle platform specifications.
Every production lot undergoes destructive adhesion testing confirming "R" failure mode (rubber tears before bond fails), hardness verification, dimensional inspection, and vertical static compression testing. Bearing torque and smooth rotation are checked on all bearing-type strut mounts. All processes are controlled under ISO 9001:2015.
