Product Details

The UMI Performance SS103050G Shock & Spring Lowering Kit is a complete, USA-made suspension upgrade designed to drop ride height by 1 inch while delivering a significant improvement in handling, cornering control, and overall driving dynamics. Whether you're cruising the street, carving corners, tackling a Pro-Touring event, or making light drag passes, this kit provides the performance foundation your build demands.

Lowering Springs:

  • 600 lb/in front spring rate and 130 lb/in linear rear rate for a firm yet comfortable performance ride
  • Wound from premium US-sourced Chrome Silicon (CrSi) wire for durability and consistent spring rates
  • Engineered for small block engine applications; lightweight LS engines may require trimming
  • A 1/4" additional front drop may occur when used with a full-weight big block engine
  • Manufactured in the USA to race-quality standards

Monotube Performance Shocks:

  • Nitrogen-charged monotube design for consistent, fade-free damping performance
  • Medium-firm compression valving for a comfortable yet performance-oriented ride
  • Ramped-up rebound valving precisely matched to control UMI's lowering springs
  • Rebound tuning reduces body roll during cornering for improved handling response
  • Race-proven shock construction built for long-term durability

The SS103050G is a complete kit made in the USA, combining matched springs and shocks engineered to work together seamlessly. This integrated approach ensures the shock valving is optimized for the spring rates included, resulting in a cohesive, high-performance suspension setup right out of the box.

Ordered a boat seat cooler. The picture in the description appeared larger than the actual size. I could tell as soon as I received it that it wasn't going to be the size I needed. I contacted them to ask if I could return it and they responded quickly with approval for a return even though I noticed on my receipt that it wasn't an item that you could return. Overjoyed they worked with me on this!

Got it quick and it was just what I ordered.

Thank you for your service and the heater came in good condition and on time it works great and I will be ordering more from you
