Torque Solution
Torque Solution Upper Differential Mount Inserts
2015+ WRX / 2015+ STI
Details
Torque Solution Billet/Polyurethane bushings are much harder compared to the OEM units. By replacing them with these harder Polyurethane units you are able to get rid of the unwanted slop and flexing of the stock units which allows for the power to go into rotating the tires, instead of flexing the rubber. Giving you better feedback, sharper response, more predictability on throttle input, along with eliminating annoying clunking during hard shifts.
- Eliminates the " CLUNK " when shifting hard
- Reduces wheel hop / traction loss
- Improved 60fts / e.t's
- 75A durometer bushings
- Limited Lifetime Warranty

Easy to Install- Great Upgrade
By G December 24, 2021Read review by Kevin. He sums everything up perfectly. Coming from a professional technician I completely agree with his experience and opinion.

Great, Quality Insert!
By Kevin June 8, 2017Rubber insert is solid (maybe more 80A) & and the aluminum sleeve is well-machined. Rear diff clunk is still there, but MUCH more muted -- more of a light tap rather than a 'punch-a-hole-through-the-steel' kind of clunk on those hard shifts. Delay between shifts seem to be a hair bit less. Would highly recommend this be installed in tandem with a trans mount and possibly even a pitch stop mount (don't forget the brace!) - or go the full mile and replace the diff carrier bushings & install sub-frame bushings/lockdowns as well! No noticeable increase in NVH. Install is simple, but be warned, it's kind of in a awkward spot -- a no-go zone for larger ratchets (especially once inserts installed). Slightly jack up the diff just to take some slack off, Loosen upper diff nuts (follow exhaust to Y-split and it's just above), grease up (or don't) the bushings and push those in, slide in the aluminum sleeve, hand tighten nuts, torque nuts to ~52 ft. lbs, lower jack, and go for a test drive. If you want to be extra cautious, use new nuts (these are self-locking).
