Most Popular Leaf Spring Enhancement System for Dodge Grand Caravan

It turned out I needed to adapt the shock kit to my trailer's frame design, so I had a welding shop make mounting brackets which are bolted on to the frame, with the shocks then bolted on. I spent, as I recall, around $130 for the welding and installation, but the shocks work work well, the ride is better, and the trailer sustains less punishment from poor or potholed roads. I'm glad I installed this kit and recommend it.

Not a trailer, but... We needed a set of shocks for a three-wheeled motorcycle truck conversion for our resort/farm in upper Thailand. I had to pack it in my luggage for the trip over. The vehicle came with no shocks on the back axle and the ride was really bad. This kit, with a bit of modification, really did the job and the ride is now significantly better in terms of smoothness and handling. Shocks were a bit long, but it worked out OK.

I installed the TSS-107-40 on a 32ft. 7500lb. travel trailer about a year ago. I also installed front axle Sumo springs SSF-302-47 and rear axle Sumo Springs SSR-312-54 on my 2022 Ram 2500. This is a review for all 3. I Have been on 7 camping trips since the Sumo springs were installed on my trailer. There's a noticeable difference on good roads. Smooths out the ride and less body roll when trucks pass me so it helps with sway. But I just took a trip down I95 through SC and the road was terrible. I mean SCDOT should be ashamed. Especially any bridges - even small ones over creeks - the dips and ramps before and after the bridges were terrible. You felt like you were being launched off of a ramp. This is where these things really did their job. They kept the contents of the trailer from being tossed and kept the trailer tracking well and immediately dampened bounce and porpoising. I also installed front axle Sumo springs SSF-302-47 and rear axle Sumo Springs SSR-312-54 on my 2022 Ram 2500 and again - noticeable difference immediately in the smoothness of the ride while towing. I bought the heavier weight springs and was worried about the stiffness of the ride with no trailer - and there is stiffness - but man am I glad I had them on the Interstate going through SC. Before I got them I could feel my suspension bottom out front and rear in certain situations. Now - not a problem. You'll have to be ok with a stiffer ride when not pulling a trailer - but you'll be happy you have them during stressful highway driving. I keep a lot of weight on my truck even without a trailer - bed cap, bed slide, tools and other items so that helps with the stiffness when not towing. I also installed the spacer on the truck rear Sumo Springs so they are engaged all the time. Not installing the spacers may help with the stiffness. I may take my spacers out. Easy installation for the most part. I did it with 2 jacks and a jack stand. The trailer Sumo Springs were even easier than the truck springs. Just be aware that these springs - IMO - are not to improve the comfort of your truck ride in general but more to improve the performance of your truck while under significant load. Having said that, they did help a lot with body roll while cornering with no trailer which was kind of a nice bonus. The rear springs also helped with squatting under the hitch weight of the trailer. You may also notice on the trailer spring picture that the gas line had to be re-routed a bit - there's a kit that comes with the springs that makes that very easy - you're able to use the existing holes.

Fast and easy install. Have kept my travel trailer’s cheap China leaf springs from re-shaping themselves into an ‘n,’ from the factory ‘u’ shape. Highly Satisfied!
