I have been running Wheelers SuperBumps on my front for over a year and really like them. They are pretty transparent when compared to the OEM bump because they engage early but have a good amount of squish to them.
After a couple bottom out situations on my last trail ride I decided to give the rear bumps a try after I saw them for sale.
Installation was a very easy:
Remove Wheel
2 x 12mm bolts per side.
Zip tie ABS wire to hard line per Wheelers Directions. It may or may not be required, I did it anyways.
I recently re-did my rear lines to SS braid... they don't route the same way, be sure to check clearances.
