Easy install
Easy install and very robust/heavy like the OEM part. Excellent tool provided to take the original bolts out to reuse. Took less than 6-7 minutes per side to install. The original bolts are torqued hard, so make sure the hex is deep in the bolt to avoid stripping (didn’t happen to me but I am 6’5” and 240 lbs). For those not too strong, use a pipe or other thing to extend the torx tool for better power. Very well made product and easy to install. In comparison side by side (one seat original and one seat with new bracket) there is additional recline of over and inch, may even inch and a half.

Easy to install and provides a more comfortable ride for passengers
There seems to be a ton of these brackets out there. I dont know if they are all coming out of the same factory, but everything about these brackets seems very good. It comes with the tool to remove the original brackets and the entire process takes just a few minutes. The reward for your efforts is a rear seat-back that is now reclined a few more degrees. You sacrifice a bit of cargo space (I feel a negligible amount), but if you have or plan to install anything in your rear space, just know that the interior dimensions of the cargo area is now different. My passengers have given a thumbs up for improved comfort in the rear seat. They originally complained that the seat backs were too vertical, especially on long drives. I am still keeping the original brackets just in case I need to switch back, but I doubt I will ever do that.

GREAT bracket, adds little over 6 degrees in rear recline, excellent product.
Was an easy install on a 24' Grenadier using the torx wrench included with the bracket set. Quality product, same quality as oem bracket. Adds > 6 degrees to rear recline angle (seat cushion not involved, this is not a block to prop the front legs of the rear seat up). Fantastic product.

Easy to install and improve the comfort of the back seat.
Great product as the quality matches the OEM part. The 6 degree difference does impact the comfort of the back seat positively. Very easy to install. Maybe took 20 minutes.
