Product Details

The Super Springs CSS1125 Coil SumoSprings are progressive-rate helper springs designed to fit between the coils of both front and rear factory coil springs. Manufactured from micro-cellular urethane, these innovative suspension enhancements increase your vehicle's load-carrying capacity by 10-20 percent while maintaining ride quality.

Key Features:

  • Universal coil spring design fits both front and rear applications
  • Micro-cellular urethane construction with progressive spring rate
  • Superior damping properties provide cushion effect during compression
  • Increases coil spring capacity by 10-20 percent
  • Improves load leveling ability without harsh ride quality
  • Simple installation - slides between existing coil spring turns
  • No drilling, welding, or permanent modifications required

Important: Inspect your coil springs before ordering to ensure adequate clearance between coils. SumoSprings are designed to enhance your vehicle's load-carrying ability but should never be used to exceed the manufacturer's Gross Vehicle Weight Rating (GVWR).

SumoSprings work progressively, meaning they engage gradually as weight increases, providing support when you need it while maintaining comfortable ride quality during normal driving. Ideal for vehicles that regularly carry heavy loads, tow trailers, or experience sagging under weight.

Very easy to order hopefully will come in on time

Everything was great, will use this site again!

Fast and Easy

I ordered a WeatherTech cargo liner from Autoplicity after finding the product almost $40 cheaper than anywhere else. Usually I'm suspect of the one company with a very low price but the high number of reviews gave me enough comfort to order. The product came in a large box and was shipped for a very reasonable price and arrived in four business days. The product is as described and I couldn't be happier. I will definately keep them in mind for future orders.

I had just bought a body lift and spacer for truck, and sure enough it all came in a timely fashion. This site is a great one to check out if you need any parts. Easy access, quick processing, I believe this is the,site ill use fot now on.

Order was quickly processed, good price too.

Quick and easy

Cheapest price I found! And super speedy deliver! Impressed!

They have hard-to-find items that ship immediately, excellent turn-around time on the orders. I look here first.

Great service. Shipped out the day after I ordered it...plus it was the cheapest of the competition.

Greatest web site i have been to in a long time. Great products, affordable prices, and my item wa shipped fast. I would highly recommend and i will be back.
