Features & Product Details

This Beatrush Rear Differential Tension Bar is a great piece to help firm up the movement of the rear diff as well as give you something pretty to look at. The stock diff mount uses rubber bushings which allow you have a quiet ride, but allow the diff to move around. This Beatrush unit has polyurethane bushings which will transmit a bit more noise in the cabin, but will really hold the diff in place.

Much better than the stock unit in terms of bushing quality. Put the car on four jack stands, then support the rear differential with a jack/block of wood. Remove the two bolts holding the tension bar to the bottom of the rear differential, then remove the two bolts securing the bushings. If the new one is not going on properly, lower the jack slightly to line up the bolts holes. Overall a tighter rear end feel but with not much increase in NVH that i can hear.

Don;t know what the fitment issues are all about! 5 years ago

It was interesting reading some of the reviews about the fitment of this product. The fitment was spot-on on my 2013 STi, and the support has made a truly noticeable improvement in the response of the rear diff to power. Don't wait, just get this!

I had a problem wt the brace touching the diff. We had to shim it to make it work. Solid design though no noticeable NVHS happy with product

not the best fitment 7 years ago
3out of 5stars

this piece is not anodized like it looks like in the picture. it is painted i think. fitment was not great, the holes do not line up perfectly so i had a hard time installing it. i had to wedge a screwdriver on top of the diff so that the bolts would stay put. then i used a mallot to tap the bar in place. then had to use a screwdriver and mallot to line everything up.

  • Q: 15+ wrx fitment  dfoy01124253 years ago

    Since you have confirmed that this part will fit the 15+ STI, would it be safe to assume that it will also fit the 15+ WRX?

      A:  This bar would more than likely fit a 2015 STI, but Beatrush has not tested fitment yet and we cannot guarantee fitment at this time.
