Jack Rubber Support Block

The Jack Rubber Support Block is a precision-engineered automotive maintenance accessory, tailored to deliver stable lifting support, reliable underbody protection, and enhanced operational safety for a wide range of vehicles. With exact dimensions of 55×43mm—calibrated to fit standard jack saddles and vehicle lifting points—this block serves as a critical buffer between the metal jack and the vehicle’s chassis, compatible with floor jacks, bottle jacks, hydraulic jacks, and scissor jacks. Ideal for passenger cars, compact SUVs, and light commercial vehicles, it effectively eliminates the risks of slipping, scratching, and structural damage caused by direct metal-to-metal contact during lifting. Whether for professional workshop maintenance, tire replacement, or DIY vehicle care, this 55×43mm rubber support block combines robust performance with a space-saving design, making it an indispensable tool for safe and efficient lifting operations.

Core Features

1. Premium Rubber Construction for Durable Support

Crafted from a high-density blend of natural rubber and synthetic rubber, the support block boasts exceptional toughness and load-bearing capacity, supporting up to 3.5 tons—perfectly suited for lightweight to mid-weight vehicles. The advanced rubber formula ensures excellent compression recovery and low permanent deformation, maintaining its 55×43mm shape and structural integrity even after repeated heavy-load use. It also exhibits strong resistance to wear, aging, oil, and extreme temperatures (-35℃ to +80℃), withstanding harsh environments from indoor garages to outdoor emergency scenarios. Unlike low-quality alternatives, it resists tearing, cracking, and degradation, ensuring long-term reliability and consistent performance.

2. Precision 55×43mm Design & Enhanced Stability

Molded to exact specifications with dimensions of 55×43mm, the block features a compact, flat profile that fits securely onto standard jack saddles and aligns perfectly with vehicle lifting points. Its textured surface maximizes friction between the block, jack saddle, and vehicle underbody, effectively preventing slipping, shifting, or dislodgment during lifting—even under heavy loads. The 55×43mm contact area distributes lifting force evenly across the vehicle’s jack points, frame rails, or pinch welds, minimizing pressure concentration and reducing the risk of chassis damage. This precision design balances stability and maneuverability, ensuring a smooth, controlled lifting process for both professionals and DIY enthusiasts.

3. Comprehensive Underbody Protection

The soft, resilient rubber surface acts as a protective barrier, isolating direct metal-to-metal contact between the jack and the vehicle’s delicate underbody components. It effectively prevents scratches, paint damage, dents, and cracks on plastic jack points, painted chassis panels, thin-walled rocker panels, and frame rails—common issues caused by unprotected jacks. By safeguarding these vulnerable parts, the 55×43mm block helps maintain the vehicle’s structural integrity, preserves its resale value, and avoids costly OEM component repairs. The rubber material also absorbs minor shocks and vibrations during lifting, further reducing the risk of damage and enhancing overall safety.

4. Universal Compatibility & Effortless Use

Designed for universal fit, this 55×43mm rubber support block is compatible with most standard jack models and a wide range of lightweight to mid-weight vehicles, including passenger cars (sedans, hatchbacks, coupes), compact SUVs, and light commercial vehicles (vans, small trucks). No specialized tools or modifications are required for installation: simply place the block onto the jack’s lifting saddle, align it with the vehicle’s designated lifting point, and start lifting—setup takes mere seconds. Its compact 55×43mm size makes it easy to store in toolboxes, vehicle trunks, or workshop drawers, ensuring convenient access whenever needed. The versatile design adapts to various lifting scenarios, making it a practical addition to any maintenance toolkit.

Quality Assurance

This Jack Rubber Support Block complies with international automotive accessory quality standards (ISO 9001, IATF 16949) and undergoes rigorous performance testing, including load-bearing tests, compression fatigue tests, high-low temperature resistance tests, and aging tests. Each unit is inspected for dimensional accuracy (ensuring strict adherence to 55×43mm specifications), material quality, and functional performance to ensure it meets or exceeds industry requirements. The block’s durable rubber construction is resistant to tearing, cracking, and degradation, ensuring long-lasting performance even with frequent use. Supplied as a single unit or in value packs, it offers cost-effective protection and safety for both professional and personal use. Choose this high-quality 55×43mm Jack Rubber Support Block to elevate your vehicle maintenance experience, protect your valuable vehicle, and ensure safe, damage-free lifting every time.
