U.S. RubberShox DuraTPE Series Front-Rear Car Coil Spring Buffer Cushion/Automotive Suspension Shock Absorber Retainer Performance Booster Kit Universal Type A-F Vehicle Auto Parts (CSB, F)

Our 2002 Acura MDX front struts were replaced at 116K with decent Monroe aftermarket parts. The OEM springs were reused. Around 135K, the struts started to feel softer with more lean in turns and excessive diving during braking. It was easy to bottom out the front end over easy bumps. The strut gas shocks are still fine it's just that the springs have aged so there's a lot more front end motion that doesn't inspire confidence in normal handling. At 153K, I replaced the rear shocks since they were original but this did not make a major improvement in overall handling.I considered replacing the front struts and springs with new parts but there's no guarantee that the new springs would provide a stiffer ride. I'm not excited about spending $600 or more to replace struts only to get minor improvement. After a bit of research, I discovered that RubberShox appeared to be a simple solution worth trying to restore a higher spring rate. The MDX coil gap (vehicle lifted) measures 1.90-2.00 inches so I chose the DuraTPE-A size that has an H2 of 1.85. According to RubberShox and other reviews, H2 should match your coil spacing for optimum performance but the spacers can be very difficult to install when these dimensions are close to each other (do NOT choose H2 greater than your coil spacing since it will be virtually impossible to install). As it turns out, I had no trouble installing the A-size and they were a perfect fit. Yes, it took some effort and WD-40 but if you follow the instructions and work by slowly feeding the spacer into the coil, keeping the upper groove fully engaged and leaving the lower groove to be slowly "popped" over the coil as you go, then it works great. I did not trim the spacer in any way but I did use a wooden handle to provide additional leverage to get the lower spacer groove to "pop" over the coil at various points. Once done, this RubberShox spacer is perfect fit as you can see in the photos. I slowly worked the spacers up towards the top of the strut so that they would be somewhat hidden in the strut tower cavity. The overall lift in the front end is about half an inch and looks like the original OEM height now.The improvement in ride and handling is like having a whole new vehicle! You would think that the ride would be stiff but it's not --bumps are smoother and the chassis feels controlled once again. No more excessive leaning in corners and nose dive during braking is minimal. I would say the car handles as good as or better than when new. Such a simple and economical fix! Try this solution if your springs feel soft or worn out, it's a great product.

Lo pedi con la caracteristica B (H2=1.22"), llego con logotipo de medida "B", pero la medida real que trae en H2 es de 1.10" (29mm), trae una tabla de medidas pero todas las medidas concuerdan con la medida "C" por lo cual antes de comprar ccertifiquen con vendedor las medidas, no me sirvio pero es mas complicado devolverlo asi que me quede con el, pero no comprare mas con proveedor por que ya no tengo confianza de sus ventas.

Stiffened up suspension nicely. Got about an additional 1/4" of lift with a perfect fit between spring when vehicle on jack. Note used sizes "A" (rear) and "A+" (front). Wish new SUVs with struts were this firm from factory when taking curves. A little bouncier over speed bumps, but not uncomfortably so. Solved towing problem of bottoming out. But don't forget tie wraps. 4 were supplied (2 for each wheel). Used 4 / wheel. Originally, planned on placing two durashocks on each strut. But after test drive with just one, it was clear 2 weren't required.Update 29mar2020:Oh well! Rubber tore in half and dislodged from the spring without even towing anything.

I bought these to stiffen up the rear suspension on my car. I put oversized wheels and tires on and had some rubbing on my fenders. I used the chart provided and got a perfect fit. Before I installed them every time i hit a large bump or dip my tires would rub. After install I don’t have any rubbing and shortened my suspension travel my about 3/4 of an inch. Saved me a couple hundred dollars on coil springs. I will definitely be buying these for future projects.

Product arrived fast. Just installed it and the right and left front increase height by 1/2". Easy to install so long as you have wd-40. Bout to test drive to feel how the ride is.
