SW 1150897 Plastic Dampener Adjustment Kit: Abrasion-Resistant & Easy-Install for Grammer 90.3

2025-10-11

In truck seat repair scenarios, Grammer 90.3 series seats are widely used for their high comfort. However, data shows that 82% of such seats develop "wear-induced cracking and adjustment jamming" in original dampeners after 1 year of use. The noise from direct metal-to-metal contact not only affects cab quietness but also accelerates the aging of adjustment mechanisms, increasing maintenance frequency. As a brand specializing in heavy-duty truck seat parts, SW recently launched the new (OE:1150897) plastic dampener adjustment kit, centered on abrasion-resistant plastic dampener and designed with easy-install damping plastic dampener features. Tailored exclusively for Grammer 90.3 seats, it provides an all-in-one solution to the wear pain points of original damping systems.

I. Core Advantages: Abrasion Resistance + Easy Installation, Redefining Grammer 90.3 Seat Damping

This (OE:1150897) kit is not an ordinary repair part but optimized for the characteristics of Grammer 90.3 seat Adjustment mechanisms, balancing durability and installation convenience:

1. Abrasion-Resistant Plastic Material, 2x Longer Service Life Than Original

As the core carrier of abrasion-resistant plastic dampener, the kit breaks through traditional limitations in material:

Main Material: Adopts PA66 + glass fiber reinforced plastic, with a Teflon wear-resistant coating on the surface. The friction coefficient is as low as 0.15 (compared to 0.25 for ordinary plastic). After 500 cycles of steel brush friction testing (5N pressure), there are no obvious scratches—far better than original ordinary plastic dampeners (which show wear after 300 cycles);
Anti-Aging Performance: Added with UV stabilizers and antioxidants, it undergoes alternating cycle tests of 80℃ high temperature and -30℃ low temperature (48 hours each) with no embrittlement or deformation, adapting to extreme temperature differences in truck cabs;
Damping Effect: Through a bionic honeycomb structure design, the dampener has a compression rebound rate of 90%, effectively absorbing the impact force of metal parts during adjustment. It reduces the seat adjustment noise from 65dB (original) to 40dB (equivalent to normal conversation volume). A driver from a logistics fleet commented: "After replacing with the SW kit, there’s no more ‘squeaking’ when adjusting the seat—the cab is much quieter."

Third-party testing shows that the average service life of this abrasion-resistant plastic dampener is 3 years, twice that of the original dampener (1.5 years).

2. 10-Minute Easy Installation, No Professional Tools Needed

In line with the design concept of easy-install damping plastic dampener, the kit is fully simplified in the installation process:

Structural Compatibility: The dampener dimensions match the Grammer 90.3 seat adjustment mechanism 1:1, with pre-reserved original screw holes. No drilling, cutting, or welding is required—directly replacing the original dampener;
Tool Simplification: Installation can be completed with just a Phillips screwdriver—remove 2 fixing screws on the outer side of the adjustment mechanism, take off the old dampener, align the new kit with the buckle, and tighten the screws. The entire process takes 10 minutes, saving 2/3 of the time compared to traditional maintenance (which requires professional wrenches and takes 30 minutes);
Beginner-Friendly: The kit comes with an installation diagram, marking the screw removal sequence and dampener installation direction. Even drivers with no maintenance experience can complete the replacement by following the diagram.

A truck repair shop technician commented: "Previously, replacing Grammer 90.3 dampeners required special tools. Now with SW 1150897, one screwdriver is enough—I can repair 5 more trucks every day."

3. Precise Fit for Grammer 90.3, Suitable for Multiple Scenarios

As an exclusive kit for 1150897 new grammer 90.3, the product achieves "original-level compatibility":

Seat Coverage: Precisely fits Grammer 90.3 series seats, including those installed on heavy trucks such as Volvo, MAN, and Scania—no need to worry about incompatible interfaces;
Function Compatibility: Does not affect the original adjustment functions of the seat (e.g., forward/backward sliding, backrest angle adjustment). The dampener only acts on metal contact parts, ensuring the adjustment stroke is consistent with the original (error ≤1mm);
Scenario Adaptation: Whether for high-frequency adjustment in long-haul logistics trucks or bumpy working conditions in engineering vehicles, the kit can stably exert damping effects, preventing dampener detachment caused by vibration.

II. Technical Details: Customized Design for Seat Adjustment Scenarios

To ensure the long-term reliability of the 1150897 kit, SW incorporates detailed designs tailored to the usage characteristics of Grammer 90.3 seats:

1. Dustproof & Anti-Jamming: Avoid Impurities Affecting Adjustment

Dustproof Structure: A silicone dust cover is added to the outer side of the dampener, preventing cab dust and debris from entering the adjustment mechanism and avoiding adjustment jamming caused by impurity accumulation;
Self-Lubricating Design: The Teflon coating has inherent lubricating properties, eliminating the need for additional lubricating oil during adjustment and reducing subsequent maintenance steps.

2. Safety Redundancy: Dual Protection Against Failure

Overload Protection: The dampener has a built-in metal reinforcing frame. When the pressure exceeds 100N (e.g., forced adjustment due to driver misoperation), the frame prevents the dampener from breaking and avoids jamming of the adjustment mechanism;
Status Indication: Wear scale lines are printed on the dampener surface. When the coating wears down to expose the base color, the scale lines change color, reminding users to replace the dampener in time to avoid direct metal-to-metal contact due to dampener failure.

3. Strict Quality Control: Three Tests for Each Kit

Produced by a factory certified to IATF 16949, each 1150897 kit undergoes three tests before leaving the factory:

Abrasion Test: 500 cycles of steel brush friction, no obvious wear;
Dimensional Accuracy Test: Key dimensions (e.g., thickness, hole diameter) have an error of ≤±0.02mm, ensuring compatibility with the original mechanism;
Damping Performance Test: Simulate 1000 seat adjustments, damping effect attenuation ≤5%.

III. Scenario Adaptation: Covering Core Usage Scenarios of Grammer 90.3 Seats

Whether for long-haul logistics or engineering transportation, this 1150897 kit can accurately meet needs:

1. Long-Haul Logistics: Quiet Damping Reduces Fatigue

Grammer 90.3 seats are often used in long-haul heavy trucks, with drivers adjusting the seat 4-6 times a day on average. Tests by a cross-provincial logistics fleet show that after installing the SW kit, cab noise is reduced by 25%, driver fatigue rate during long hauls drops by 18%, and driving efficiency increases by 10%.

2. Truck Repair Shops: Efficient Replacement Lowers Costs

The time to replace Grammer 90.3 dampeners in repair shops is reduced from 30 minutes to 10 minutes, cutting labor costs per vehicle by 50%. At the same time, due to the kit’s improved durability, the customer rework rate drops from 30% to 5%, significantly enhancing the repair shop’s reputation.

3. Old Vehicle Renovation: Low-Cost Performance Restoration

For trucks over 3 years old equipped with Grammer 90.3 seats, replacing with the SW 1150897 kit costs only 1/3 of the original parts, restoring the seat’s damping and quiet performance. A used car renovator said: "After installation, the seat adjustment experience is comparable to that of a new car, increasing the vehicle’s residual value by 8%."
