Shock absorber bottom bracket. Note: Check your ubolts are 10mm longer to accept this bracket.
Brackets are available for left and right sides.
Brackets can be turned upside down to provide extra length or shorten the travel in your shock absorber.
Further, one slotted hole accommodates 45mm or 50mm springs.
The brackets are chiefly manufactured to fit 60mm spring packs.
Firstly, measure the length of your bolt below the nut. If you have an extra 10mm thread then longer u-bolts are not required.
Secondly, tightened up your ubolts on the diagonal and re-check the tightness after 200 kilometres.
