Prothane Differential Bushings

Improving Your Vehicle's Reaction Time

Whenever your vehicle is moving, your engine is sending power down the driveshaft through your differential. As the differential reacts to shifts in power, the OE bushings mounting it to the frame are prone to flexing. This flexing reduces the efficiency of the differential's power transfer from the driveshaft to the wheels, resulting in slow accelerations and decelerations.

The reason the OE bushings flex is because they are made of rubber. In addition to flexing, rubber is also prone to wearing down due to contaminants and impacts. Prothane, on the other hand, offers solid polyurethane differential bushings. Polyurethane is much more durable than rubber, handling physical wear and chemical contamination with equal ease. In addition to the added durability, these bushings are also much firmer than rubber. Thanks to this firmness your differential won't move around as much, instantly improving your vehicle's reaction time. In addition, Prothane covers all of their differential bushings with a lifetime warranty handled in-house here at DST.

WoW. First off I would like to say amazing service, shipping from Texas to Canada I got it the next day!! Would highly recommend ordering from this company over any other! I have only had the bushings in for a very short time. But as soon as you leave the driveway, you notice the improvement right away:)
5 out of 5 - Very Happy

I was skeptical. Boy was I wrong. THIS is how a WRX should come stock from the factory. I installed this kit along with new swaybar endlinks & poly swaybar bushings & it became a totally different car. This really is one of the best bang for the buck mods you could do to any manual Subaru around. My smile was nonstop all day today. For reference my WRX has 64,000 miles on the clock so not much wear. This kit plus the swaybar hardware is A NIGHT & DAY DIFFERENCE. I couldnt IMAGINE how this would feel on a 100,000+ mile car...

The shipping was fast, the product was easy to install and works great! I would recommend this to any Subie owner looking to slightly firm up the rear differential bushings.

Installed on the rear of my 2014 Subaru WRX 5dr in about 20 minutes. Followed the (very easy) instructions and got rid of the "rear end" clunk. Be sure to use the supplied lube to run around the metal diff carrier holes (the edges are an interference fit with the bushing insert, this makes it MUCH easier to install). Half the price of the Whiteline kit and it came with GIANT grade 8 washers to make sure the inserts never move. I wouldnt hesitate to do this again.
5 out of 5 - VERY easy to install, GREAT upgrade
