Constant rate front coil springs can help improve stability and maintain ride height

Variable rate rear coil springs provide 500 lbs (per pair) of load capacity. Not to exceed vehicle gvwr (gross vehicle weight rating). The product does not increase payload

Seamless drawn-over-mandrel (dom) tubing decreases internal component wear, resulting in longer service life. Compressed length: 8.67 inch

C Type -- Gapping of Spring: 27mm Spring Thickness: 10mm Spring High: 55mm Spring Diameter: 131mm

Effectively solve problem of springs weakness when heavy load & improve performance of shock absorber.

Improve driving comfort and more stable during curve corner.

F Type -- Gapping of Spring: 12mm Spring Thickness: 15mm Spring High: 38mm Spring Diameter: 120mm

Effectively solve problem of springs weakness when heavy load & improve performance of shock absorber.

Improve driving comfort and more stable during curve corner.

🚗【Product Dimensions】：Choose Size A, if the Car Coil Spring Gap (when lifted and unloaded) is between 2.35”-2.6”. *Please lift the vehicle to measure the Gap. Coil gap may vary between brands and years of use. Also refer to Size Chart in Photos and User Manual in Technical Specification.

🚗【Supported Weight & Package Contents】：Designed for sub-compact to mid-size sedans- 2000-3500Lbs GW. Added up to 1” ground clearance. Up to 2” if combined with Rubber Block Boosters. DuraTPE material with full ring design, reinforces Automotive Coil Spring Buffers/shock absorbers (2pc. Per pack – multiple size options).

🚗【Durable Material & Performance Enhancement 】： DuraTPE Thermoplastic Rubber - Environmental friendly and Resistant to coil abrasion, oil, salt, gravel & UV radiation. Enhances driving stability while extending the life of coil springs and the suspension system. Please check the template below to choose the correct buffer size.

MAINTAIN RIDE HEIGHT UNDER LOAD -- Air chamber can be inflated or deflated up to 150 PSI to maintain level height with additional weight up to 1,200 lbs. (capacity is limited by suspension, tires and transmission; see owner's manual)

EASY TO ADJUST -- Special air fitting resists air leakage and ties into factory system (where applicable) or manually inflates with an air compressor; pair with Monroe air shock accessory and shock air hose AK kits (varies by application)

EXCEPTIONAL HANDLING -- Full-displaced valving on compression and extension cycles for a smooth ride

This Anodized Aluminum RC Car accessories package set is specially designed to E- Maxx 3903, 3905, and 3908, definitely a good upgrade purchase for your RC car. They are all hand-polished first before being anodized for better performance and cool appearance.

【Comfortable ride】: Adopting the principle of buffering, the shock absorption performance is significantly improved. Effectively cushion and absorb the momentary pressure caused by rough roads, avoiding damage to the shock absorption system.

【Stability performance】: When passing through non-tarmac roads, bumpy roads, and sharp turns, the stability is significantly improved, and the body can be lifted by 0.2-0.3 cm. For cars that have been used for a long time, it can effectively solve the problem of weak shock absorber springs and restore shock absorber performance.

【Noise reduction】: Restrain the vibration of the vehicle body caused by uneven road surface during the driving process, effectively reduce the vibration of the vehicle body, thereby reducing the vibration noise of the vehicle.

All products are designed to meet OEM Quality. The complete strut - Coil Spring (Load Strut/Quick Strut) is easy and safe to install. No need to take apart existing strut assembly, no need to compress coil springs, and no specialized tools needed. The bare struts & shock absorbers improve steering and handling, braking ability and overall safety.
