DuraSHOCK DuraTPE Pro Series, Front-Rear automotive coil spring buffer/booster kit

A part le fait que c’est un peu difficile de choisir la bonne grandeur, le produit fait ce qu’il a à faire en donnant une rigidité additionnelle à ma suspension arrière car aucun autre produit n’était compatible avec mon Santa Fe.

Coil spring boosters are not new. Superior Automotive has sold them for years through OReilly Auto and other auto stores, Speedwaymotors which caters to circle track racing has also sold them. However, these RubberShox have the variety of sizes to actually most likely fit your car, unlike the limited previously mentioned offerings. Some advice regarding fit: - The diameter of the booster is not as important as the spacing between the coils (corresponds to the H2 on the booster) and the actual coil rod diameter (G2 on the booster). - You MUST pick a booster that has a smaller H2 dimension than the spacing between your extended coil spring. It CANNOT be close or bigger. I originally got the A size for my car thinking that even though the H2 at 1.85" was close to my spring spacing of 1.75" I could force it. Wrong. Brutally wrong. There must be free space to feed the booster onto the coil. Even with the B size I got, which has an H2 of 1.22" getting the booster on still took some serious pushing and finger strength. - Most springs have smaller spacing between the coils towards their ends. Hence, I installed these boosters near the middle of my springs and then rotated them towards the end of the springs. This wedged them into place. Even though zipties were included with my boosters there were no holes in my boosters for them, and I wouldn't nor saw any need to drill holes in my boosters to use the zipties. - Rubbershox says you can use WD40 to mount these. That's controversial as people have said WD40 deteriorates rubber, I used soapy water. The results are fantastic. Concerning raising the rear ride height, that is negligible. Immediately after install there was an increase of 1/2", but it didn't take long for that to settle out right back to the original height. But under dynamic load and motion it is obvious that the rate of my rear springs has noticeably increased. Cornering is spectacularly better. Even at low speeds in parking lots the steering is noticeably tighter. At higher speeds there simply is less body roll, and hence less steering input is needed. I'm content enough that I don't feel the need to get boosters for the front. I have the Pro for the rear (black) and was going to get the standard (red) for the front, but I'm fine with how the thing handles for now. I do recommend for most vehicles that the rear be stiffened before the front. Stiffening only the front will promote understeer. Especially on longer vehicles such as vans and minivans stiffening the rear in comparison to the front will aim towards oversteer and sharpen steering input. There is a lot of torsional twist that occurs in longer bodies and stiffening the rear helps counter that. This is definitely a best bang for buck mod for a car like my van. There is no detrimental harshness. Going over speedbumps is clunkier and louder, but it's a compromise I'm perfectly happy with. My only concern at this point is durability, which remains to be seen.

FYI, This is very difficult to install but the correct pick for a 2011 Highlander. Luckily on this car, the spring's lower coil is larger and has a wider spacing. So you can get the A+ spacer started at the bottom and work it up into the narrower coil with difficulty. The A size would be easy peezy to install but probably do nothing to stiffen the suspension. The improvement in trailer towing is slight but the car does handle better with the Shox. Height at the rear axle was raised 1" and 1 1/2" at the hitch ball. This company needs to get it's act together as far as a fitment chart. The product seems to be of good quality.

Make sure you measure first and order the correct spacer for your springs. It is incredibly difficult to install it on the vehicle even if the vehicle is on jack-stands. Use lots of soapy water and make sure you clean your springs well before fitting or installation. Keep the rubber well lubricated with soapy water during your install. I installed a strut lift as well that required my strut to be removed before placing it on the vehicle. It was a little easier to put it on this way but I don’t recommend it as it requires a lot of time and patience. There is noise reduction after installment It also raises the ride height of your vehicle just a little bit Overall I believe it is 10 out of 10 And I will buy some more for my next vehicle

Use size B for 16-22 Pilot rear ends. Trim the inside corners down like they suggest in the posting, make sure to get some sort of lubricant to help slide them on. I have a 2.5”F/2”R ready lift kit installed on my Pilot and had considerable sag in the back after adding a rear tire carrier and full size spare. You will have to shorten the overall length of the bushings by about 2”, but now I have 10” of clearance at the front and rear diffs again. Had them installed for about a week now and notice the ride has improved considerably and I have zero noise coming from the rear. Make sure to disconnect your rear sway bar so you have adequate room to work these in, not a fun install process but necessary and totally worth it. Would be nice if these had the pass thrus for the zip ties but how I have them installed should be fine and with how difficult these were to put in I don’t think they’re going anywhere anytime soon. For the price vs their competitors I would definitely recommend them, hopefully the materials don’t dry rot out too quick, only time will tell.
