Overview
The Losi Bellville Disc Spring, HD Servo Saver, Med (12): LMT 2.0 is an essential replacement component for owners of high-performance RC monster trucks and rock crawlers. This pack contains 12 genuine Belleville disc springs engineered specifically for the Losi LMT 2.0 platform, one of the most capable 1/8 scale solid axle monster trucks available in the UK RC market. Whether you're a serious basher tackling rough terrain or a competitive racer pushing your vehicle to the limits, these servo saver springs are crucial maintenance items that protect your drivetrain from shock loads and impact damage.
Belleville disc springs, also known as Belleville washers, are specialised components that provide consistent spring force and load distribution in servo saver assemblies. Unlike traditional coil springs, these conical-shaped discs offer superior performance characteristics and reliability, making them the preferred choice for demanding RC applications. For UK RC enthusiasts running the Losi LMT 2.0 Grave Digger or SonUva Digger variants, having genuine replacement springs on hand is essential maintenance practice, ensuring your servo saver remains effective at protecting expensive electronics from costly damage during high-impact driving.
These medium-rated springs are designed to work seamlessly with the HD servo saver system on your LMT 2.0, providing the perfect balance between responsiveness and protection. The 102 lb spring rate delivers consistent performance across a wide range of driving conditions, from rock crawling on rugged terrain to high-speed bashing on jumps and obstacles. Stocking a spare set of Belleville disc springs is smart preventative maintenance that every LMT 2.0 owner should consider.
Key Features
- Set of 12 Belleville Disc Springs — This pack includes a complete set of 12 genuine Losi Belleville disc springs, providing you with multiple springs for maintenance, replacement, or tuning your servo saver assembly to suit different driving styles and conditions.
- 102 lb Spring Rate — The medium spring rate of 102 lb has been engineered to provide the optimal balance between servo protection and steering responsiveness for the LMT 2.0 platform, ensuring your servo saver reacts appropriately to impacts whilst maintaining precise handling characteristics.
- Precise Dimensions — Each spring measures 10.2mm x 20mm x 0.6mm, matching the exact specifications required for the Losi LMT 2.0 servo saver assembly, ensuring perfect fitment and reliable performance without modification.
- HD Servo Saver Compatibility — These springs are specifically designed for the heavy-duty servo saver system on the Losi LMT 2.0, providing superior durability and protection for your expensive servo and steering components during demanding off-road driving.
- Genuine Losi Component — As an authentic Losi part, you can be confident in the quality, material composition, and engineering standards that meet the manufacturer's exacting specifications for reliable performance.
- Essential Maintenance Item — Belleville disc springs wear over time with repeated impacts and harsh driving conditions, making replacement springs an essential maintenance consumable for any serious LMT 2.0 owner.
Technical Performance
The Losi Bellville Disc Spring represents precision engineering at its finest, utilising conical spring technology that has been proven in demanding RC off-road applications. The 102 lb spring rate is specifically calibrated for the LMT 2.0's servo saver assembly, which is one of the most critical protection systems on any 1/8 scale solid axle monster truck. When your LMT 2.0 encounters a sharp impact—whether landing hard from a jump, striking a rock during rock crawling, or colliding with obstacles at high speed—the servo saver springs compress to absorb the energy and prevent that shock load from being transmitted directly to your steering servo and servo horn. This mechanical protection is invaluable, as servo replacement costs often exceed £50-100 for quality units. The medium spring rating means these discs offer aggressive protection without being so stiff that they reduce steering response or create dead spots in your vehicle's handling. The precise dimensions of 10.2mm x 20mm x 0.6mm are engineered to stack correctly within the servo saver assembly, distributing load evenly across all springs for consistent, predictable performance. Unlike inferior aftermarket springs that may have inconsistent dimensions or material quality, genuine Losi springs maintain their rate and responsiveness even after repeated compression cycles, ensuring your servo protection system remains effective throughout the season. These springs are made from high-grade steel that resists fatigue and maintains its spring characteristics, making them a worthwhile investment in long-term drivetrain reliability.

Frequently Asked Questions
- What is a Belleville disc spring and why do I need it? — A Belleville disc spring, also called a Belleville washer, is a conical-shaped spring component used in servo saver assemblies to protect your RC vehicle's steering servo from impact damage. When your vehicle hits an obstacle or lands hard from a jump, the Belleville spring compresses to absorb the shock, preventing that energy from being transmitted to your servo. This protection is essential for preventing expensive servo damage and maintaining reliable steering performance.
- Are these springs compatible with my Losi LMT 2.0? — Yes, these Belleville disc springs are specifically designed for the Losi LMT 2.0 servo saver system. They are compatible with both the Losi LMT 2.0 Grave Digger 4X4 Solid Axle Monster Truck RTR and the Losi LMT 2.0 SonUva Digger 4X4 Solid Axle Monster Truck RTR models.
- How often should I replace Belleville disc springs? — Belleville springs gradually lose their spring rate with repeated compression cycles, typically after several months of regular driving or intensive bashing. If you notice that your servo saver feels less responsive or your steering servo is getting damaged more easily, it's time to replace the springs. Stocking spare sets ensures you can maintain optimal protection year-round.
- What does the 102 lb spring rate mean? — The 102 lb spring rate indicates the stiffness of the spring—specifically, how much force is required to compress it by one inch. A 102 lb medium rate provides balanced servo protection without over-stiffening the servo saver, which could reduce steering precision or allow shocks to pass through to your servo. This rate is engineered specifically for the LMT 2.0's weight and performance characteristics.
- How many springs do I need to replace at once? — The LMT 2.0 servo saver typically uses multiple Belleville springs stacked together. This pack of 12 springs provides enough replacements for multiple service cycles or for experimenting with different stack configurations to tune your servo saver stiffness.
- Can I use different spring rates on my LMT 2.0? — Whilst this pack contains medium-rated springs, Losi manufactures springs in different rates for different driving styles and conditions. The medium 102 lb rate is the standard recommendation for the LMT 2.0 and suits most drivers. Using softer springs may reduce servo protection, whilst stiffer springs might diminish steering responsiveness.
