Review: Big upgrade from stock, install was (fairly) easy - Overall a great upgrade from stock. Replaced the stock Ford bump stops with SumoSprings (sir-121-54). Not a hard install, about 1 hour. Helps with the swaying boat issues when turning and hitting a dip and windy driving. Left .5" gap of space as per the instructions, so no lift when empty but won’t dip when loaded. You need a decent jack and lift it from the back (not the side), wheels don’t have to come off. Chock the front wheels and use jacks for safety. Measure the stock distance from the top to the bottom of the Frame so you can leave about .5” to 1” of space (as in my photo). Install when the coach has an empty water tank. From there twist the factory ones off by hand and a 13mm to take off the top bolt. Then install the new bump stops with a 17mm bolt that is included. As long as you have the tools it’s easy. about 60-90 mins. there are a few youtube videos that help Review: Great upgrade to our Ford Transit 350 HD RV. - Put these on my Ford Transit 350 HD RV. They were very easy to install and make a big difference in the ride and handling. Be safe when jacking up the RV. Jack it up as high as possible to the point the wheel starts to leave the ground. You will need that space to fit your socket extensions and to remove them. ## Features - Vehicle Compatibility: These SumoSprings are specifically designed to fit your Ford Transit 150/250/350/350HD (2015-2025 RWD / 2020-2025 4WD), ensuring a perfect fit and maximum reliability - Progressive Load Support: SumoSprings compress under increasing weight to reduce rear-end sag, improve ride height, and maintain balanced handling - No Air, No Maintenance: Made from closed-cell microcellular polyurethane, these springs don’t require airlines, compressors, or constant adjustment - Smoother, Safer Handling: The progressive foam design dampens harsh impacts, minimizes body roll and sway, and boosts driver control - Built to Last: Weather-resistant polyurethane resists UV, moisture, corrosion, and extreme temperatures — backed by a lifetime warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01GNW03NM | | Best Sellers Rank | #261,116 in Automotive ( See Top 100 in Automotive ) #55 in Automotive Replacement Leaf Spring Leaf Springs | | Brand | SuperSprings | | Customer Reviews | 4.3 4.3 out of 5 stars (75) | | Date First Available | June 6, 2016 | | Exterior | Painted | | Item Weight | 5.63 pounds | | Item model number | SSR-121-54 | | Manufacturer | Supersprings International, Inc. | | Manufacturer Part Number | SSR-121-54 | | Model | SSR-121-54 | | Position | Rear | | Product Dimensions | 11 x 8 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 Set of Rear SumoSprings fits Ford Transit 150/250/350/350HD (2015-2025 RWD / 2020-2025 4WD) | 2800 lb Capacity at 50% Compression | Simple Installation - Image 1](https://m.media-amazon.com/images/I/61SdfqjjCbL.jpg) ![SuperSprings Set of Rear SumoSprings fits Ford Transit 150/250/350/350HD (2015-2025 RWD / 2020-2025 4WD) | 2800 lb Capacity at 50% Compression | Simple Installation - Image 2](https://m.media-amazon.com/images/I/812NvF385VL.jpg) ![SuperSprings Set of Rear SumoSprings fits Ford Transit 150/250/350/350HD (2015-2025 RWD / 2020-2025 4WD) | 2800 lb Capacity at 50% Compression | Simple Installation - Image 3](https://m.media-amazon.com/images/I/81ZlBokhSkL.jpg) ![SuperSprings Set of Rear SumoSprings fits Ford Transit 150/250/350/350HD (2015-2025 RWD / 2020-2025 4WD) | 2800 lb Capacity at 50% Compression | Simple Installation - Image 4](https://m.media-amazon.com/images/I/81ODnXP2f7L.jpg) ![SuperSprings Set of Rear SumoSprings fits Ford Transit 150/250/350/350HD (2015-2025 RWD / 2020-2025 4WD) | 2800 lb Capacity at 50% Compression | Simple Installation - Image 5](https://m.media-amazon.com/images/I/81N0NawSmmL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Will this fit a 2022 transit 350 RWD extended** A: It fits my 2017 Ford Transit 350 XLT HD.

It sat high and kind swayed on turns a bit, so I just added these Sumo springs, based on an internet and youtube search. I noticed and immediate improvement on my first drive with it, I am about to embark on a 5000 mile, 3 week road trip. I will see if I will add any to the front suspension also. I would recommend over the stock ones. It took me 1 hour to install both, with a floorjack in my driveway. Easy install, no problems or setbacks. I used both spacers that it came with. ## Frequently Bought Together - SSR-121-54 | SumoSprings Rear for Ford Transit 150|250|350, Yellow - SuperSprings CSS-1195 | Coil SumoSprings for various applications | 1.95 inch inner wall height, Black - SuperSprings SSA43 Black SuperSpring, 2 Pack --- ## 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/77359324-supersprings-set-of-rear-sumosprings-fits-ford-transit-150-250](https://www.desertcart.vu/products/77359324-supersprings-set-of-rear-sumosprings-fits-ford-transit-150-250) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-07*
