Easy to install !! I pull a 5th wheel camper and adding these the truck doesn’t squat like it did ! I feel l have better control and handling with them on !! Fallow the installation direction for spacing , so when you are not hauling no weight your truck will ride normal! Not like air bags that make a rough ride with no weight because you have to keep 5 lb of pressure!!! Review: Works as advertised! - I don’t write many reviews but I feel compelled to write this one. Bought these for my 2022 F350 and they work awesome! I tow a 13,000 lb. Fifth wheel and had some definite rear end squat even though I was not over weight for the axle. Was a little skeptical of these but seemed a lot easier and cheaper than doing airbags so I gave it a try. All told from unboxing to final installation was about 30 minutes. Helpful hint, I assembled them first, then used my Jack to raise the rear end a couple inches while still keeping the wheels on the ground, just to create a little space between the axle and frame. Unbolt the factory bump stops and bolt these on, simple as that. These work exactly as advertised, no more squat, so better handling and braking. Have towed my fifth wheel over 2000 miles since installing and very happy with these. Highly recommend, this is a great product! ## Features - Eliminate Suspension Sag And Cushion Road ShockReduce Sway And Improve Roll StabilityEasy To Install With Basic Hand ToolsImproves Roll ControlTrouble And Maintenance Free - Easiest to use: Rubber cushions absorb road shocks and automatically adjust to uneven loads or road conditions - Easiest to maintain: There are no airlines or fittings to allow leaks; Simply bolt the kit on and you are set for a lifetime of trouble free suspension;Easiest to install: There are no holes to drill, no airlines to route and SES Kits can be installed in a matter of minutes using basic hand tools - Suspension Enhancement System ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01NCMEA0V | | Best Sellers Rank | #70,708 in Automotive ( See Top 100 in Automotive ) #41 in Automotive Replacement Air Suspension Kits | | Brand | Timbren | | Customer Reviews | 4.6 4.6 out of 5 stars (150) | | Date First Available | January 9, 2017 | | Exterior | Smooth | | Is Discontinued By Manufacturer | No | | Item Weight | 9.48 pounds | | Item model number | FR350SDJ | | Manufacturer | Timbren | | Manufacturer Part Number | FR350SDJ | | Model | Timbren | | OEM Part Number | FR350SDJ | | Product Dimensions | 8.5 x 10.5 x 6 inches | ## Images ![Timbren FR350SDJ SES Rear Suspension Enhancement System - 8,600 lb Load Support | Progressive Load Stability & Zero Maintenance Reliability | Levels Truck, Reduces Sag, Roll & Sway | DIY Install - Image 1](https://m.media-amazon.com/images/I/51owTr7fTYL.jpg) ## Questions & Answers **Q: Will these work hand in hand with the superduty overload springs??** A: They should I don’t have the springs but do have the ford towing springs and the bump stops work great tow a 13,550 camper unloaded with a fifth wheel hitch **Q: Timbren manufacturing website states that this is the correct part for my 2017 ford f-350, but amazon "search by vehicle" says that it isn't. is it?** A: I made the mistake of buying the one Amazon recommended and it was the wrong one at the time. I would call timbren as I did and verify which ones you need. **Q: Does this work on Drw ?** A: Go to the Timbren website and enter your truck info, it will tell you what part number you need. **Q: does this kit from amazon have the spacer that goes between the main rubber/mounting bracket, incase the gap between the timbren / axle is to much?** A: Yes it comes as a complete kit ## Customer Reviews ### ⭐⭐⭐⭐⭐ Enhance your truck rear suspension!!! *by O***Y on May 6, 2025* Great way to enhance your rear suspension !!!
