They are maintenance free, do not leak air, and do not require airlines or compressors.

They are manufactured from proprietary closed micro-cellular urethane providing a smooth and progressive spring rate with superior damping properties. Review: Helpful for stability and smooth ride - These were easier to install than the front Sumo Springs and they do seem to improve overall handling and ride. I installed them shortly after getting my camper van because virtually everyone who had tried them said they made a significant improvement. They seem to be working fine three years later. Review: Much improved handling - Bought these and the front ones as well for our 2022 Dodge ram Promaster 3500 travel van. Easy in install, and the ride difference is huge. Wife thought it wasn't a smart purchase till we test drove it with the new springs. You will not be sorry you bought these. ## Features - Vehicle Compatibility: These Yellow SumoSprings are specifically designed to fit 2014-2025 RAM ProMaster 1500/2500/3500 2WD models; the SSR‑313‑54 pairs seamlessly with your factory suspension system - Reliable Load Support: Handles up to 2,800 lbs at 50% compression to keep your van steady and controlled under heavy loads; To maintain full memory rebound and long-term performance, avoid compressing beyond 55% of the spring’s original height - Smoother Ride: The micro-cellular polyurethane springs compress progressively — soft when unloaded, firmer under load — delivering a smooth, comfortable ride without sacrificing control - Rear Stability: Prevents rear sag and reduces body sway to keep your van level and stable under heavy loads or towing; Enhances safety and handling by minimizing roll, especially during sharp turns and in crosswinds, for greater driver confidence - Built to Last: Made in the USA from weather-resistant polyurethane that resists UV, moisture, corrosion, and extreme temperatures; backed by a limited lifetime warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B073RK8CHW | | Best Sellers Rank | #171,857 in Automotive ( See Top 100 in Automotive ) #65 in Automotive Replacement Suspension Coil Springs | | Brand | SuperSprings | | Customer Reviews | 4.8 4.8 out of 5 stars (377) | | Date First Available | July 6, 2017 | | Exterior | Painted | | Item Weight | 2.45 pounds | | Item model number | SSR-313-54 | | Manufacturer | Supersprings International, Inc. | | Manufacturer Part Number | SSR-313-54 | | Model | SSR-313-54 | | Position | Rear | | Product Dimensions | 14 x 9 x 5 inches | | Special Features | Compress up to 80% of original height with full memory rebound, Improves overall driver control and ride comfort, Made from patented micro-cellular urethane, One-piece unit attached on one side used as a replacement/upgrade to factory bump stops, progressive spring rate with superior damping properties | ## Images ![SuperSprings SSR-313-54 Pair of Rear SumoSprings fits 2014-2025 Ram ProMaster 1500/2500/3500 2WD | Softens Harsh Rebounds | Reduces End Sag | Stabilizes Sway | Made in USA - Image 1](https://m.media-amazon.com/images/I/61wxAHo5dWL.jpg) ![SuperSprings SSR-313-54 Pair of Rear SumoSprings fits 2014-2025 Ram ProMaster 1500/2500/3500 2WD | Softens Harsh Rebounds | Reduces End Sag | Stabilizes Sway | Made in USA - Image 2](https://m.media-amazon.com/images/I/71ufGPWLZzL.jpg) ![SuperSprings SSR-313-54 Pair of Rear SumoSprings fits 2014-2025 Ram ProMaster 1500/2500/3500 2WD | Softens Harsh Rebounds | Reduces End Sag | Stabilizes Sway | Made in USA - Image 3](https://m.media-amazon.com/images/I/81guR6WdBgL.jpg) ![SuperSprings SSR-313-54 Pair of Rear SumoSprings fits 2014-2025 Ram ProMaster 1500/2500/3500 2WD | Softens Harsh Rebounds | Reduces End Sag | Stabilizes Sway | Made in USA - Image 4](https://m.media-amazon.com/images/I/710sQ0EjZ4L.jpg) ![SuperSprings SSR-313-54 Pair of Rear SumoSprings fits 2014-2025 Ram ProMaster 1500/2500/3500 2WD | Softens Harsh Rebounds | Reduces End Sag | Stabilizes Sway | Made in USA - Image 5](https://m.media-amazon.com/images/I/81-87TnyIVL.jpg) ## Questions & Answers **Q: Which sumo springs recommended for the front on ram promaster 2500?** A: CSS-1195 fits RAM ProMaster 2500 **Q: For quantity should i order 1 or 2 ?** A: 2 are included in each order **Q: Will these work on my 2013 ram 1500 crew cab** A: The SSR-313-54 SumoSprings are for the Ram ProMaster Vans not for the Ram 1500 truck.

I installed them shortly after getting my camper van because virtually everyone who had tried them said they made a significant improvement. They seem to be working fine three years later. ### ⭐⭐⭐⭐⭐ Much improved handling *by X***R on May 1, 2024* Bought these and the front ones as well for our 2022 Dodge ram Promaster 3500 travel van. Easy in install, and the ride difference is huge. Wife thought it wasn't a smart purchase till we test drove it with the new springs. You will not be sorry you bought these. ### ⭐⭐⭐⭐⭐ height after install *by M***. on September 14, 2022* These were intalled on an already RV converted Promaster 3500.I removed one of the spacers and after install they sit 1/4 inch above leaf springs. Takes potholes much better and most of all, corners much more level with little to no sway. Hopefully this will also eliminate ,or drastically reduce, wind sway during highway miles. ## Frequently Bought Together - SuperSprings SSR-313-54 | SumoSprings Rear for Dodge RAM ProMaster 1500|2500|3500, yellow - SuperSprings CSS-1195 | Coil SumoSprings for various applications | 1.95 inch inner wall height, Black - Bilstein B6 2014+ Dodge Ram Promaster 1500/2500/3500 Rear Monotube Strut Assembly (24-245500) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/63010953-supersprings-ssr-313-54-pair-of-rear-sumosprings-fits-2014](https://www.desertcart.vu/products/63010953-supersprings-ssr-313-54-pair-of-rear-sumosprings-fits-2014) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
