Review: Simple fix for soft Acura MDX struts - 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.
Review: Kind of easy to install and make quite a bit differences. - I bought these buffers for my 2018 Mazda CX-5 front and back coil springs. My wife and I were used to drive German cars and enjoyed the handling during turn. I love the look inside out of my CX-5, but I really cannot appreciate the handling especially on the mountain road. I saw these buffer on desertcart and want to give them a try since they are not expensive at all. The installations are quite simple and easy. However, it did require to lift the car to install. Before buying the buffer, I lifted the car to measure edge-to-edge for both front and back coil spring. The best thing is, their website have detail measurement and installation guide. After lifted the car, I just slide the buffer from bottom of the coil spring (larger edge-to-edge space)all the way to the top. At my first tried, it was hard for me to slide the buffer into the spring. I emailed manufacturer and wondered if I got the wrong size buffers. I got emailed back second day and they suggest sprayed WD-40 on buffers and springs before installation. It only took me 30 minutes to install all 4 buffers to front and back coil springs of my SUV. They should put this suggestion into their installation guide. After driving my CX-5 for next 3 weeks, I am totally satisfied with these tiny cheap buffers. I was so happy for the two mountain trips I had, they made the turn so stable and smooth even with my wife and two teenage kids inside the car and they don't feel dizzy like before. These buffers are also doing very good in absorbing the road bump. I love these buffers! Draw back Although these buffers are designed as universal fit, but it is not quite tight fit to different type of the coil spring. The back of my CX-5 is not as tight as the front ones . If you want to buy these buffers, you should make sure the measurement is correct and pick the one as close to your measurement as possible. One little thing, I would like my CX-5 even stiffer. I like the stiffer driving behavior even it will scarify the comfort of absorbing road bump.
