Printed in PLA-CF they are studded and hold up well and I've not broken any in testing. These mount with the bolts inside chassis to outside rail mount for maximum inner clearance for servos and whatever else you may have in your truck
These are meant for the Stagekillah body but will fit other bodies that have similar hood and bed heights. These come with 2 body nuts, color of the nuts is your choice
Rear and to an extend the front can be adjusted forward and backward
