This aluminum Front Bumper is the ideal replacement for the wobbly factory plastic unit.
The aluminum construction eliminates slop between the bumper and mount that will plague the factory components after severe use or use with a winch.
This is a direct replacement unit requiring no modification on a TRX-4.
To fit an SCX10-II you may need to shorten the posts and/or drill new holes.
Note that the stinger portion can be removed for a lower profile.
