Aluminum Big Bore shocks come packaged in convenient 8-packs for T-Maxx^® and E-Maxx^® trucks. The Big Bore shocks are hard-anodized and PTFE-coated for smooth operation and with internal diaphragms that help keep the air and oil separated for increased performance. These shocks also include super smooth, long wearing titanium nitride (TiN) coated shock shafts. The shocks come completely assembled and include red, 2.5 rate shock springs, additional shock pistons, and clip on pre-load spacers that make ride height adjustments a snap.
