Seismic® G5™ 45-degree Spring Truck
180mm faced Hanger with 45-degree Baseplate in stone finish.
Choice of Solid or Hollow axles, Springs in four (4) strength options.
Price is for a single truck. Order two (2) trucks for one skateboard.
General setup suggestions
For optimal traction, power, and control, we usually suggest a 45-degree truck at the nose and a 30-degree truck at the tail, with stiffer springs at the tail than at the nose. Use two 45-degree trucks on symmetrical (twin-tip) freeride decks. Use stiffer springs if you’re heavier and/or taller than average, softer springs if you’re lighter and/or less tall.
The original precision longboard truck – five generations later!
A major upgrade to our flagship high-rebound truck technology.
Power, stability, maneuverability, and control since 1993
No truck has more energy return, more precision, or better steering control. The world’s best for pumping!
Stronger, lighter, and better-looking
Our crack team of engineers and industrial designers scoured every cubic millimeter of the previous (G4) model – looking for material to trim and spots to toughen, all while improving aesthetics.
More precise Spring System
Breakthrough Spring Cap design keeps Springs much straighter as they compress – resulting in a larger turning range and enhanced steering control.
Easier maintenance and better Pivot Bolt fastening
Thicker, stronger Pivot Bolt is easier to remove and install, and it threads more securely into a larger Baseplate Locknut. Stronger, reusable Pivot Bolt Clip is easy to remove and install by hand, and it’s fastened to a rubber “leash” that prevents it from ever getting lost. Ingenious new multi-part Baseplate structure creates uniform thickness at mounting corners, so you need mounting bolts of only one length.
Most components backwards compatible with older models
Exception: G5 Pivot Bolts, Baseplate Locknuts, and Pivot Bolt Clips will not fit older (G4) Baseplates; and older (G4) Pivot Bolts, Baseplate Locknuts, and Pivot Bolt Clips will not fit G5 Baseplates.
Seismic G5 Baseplates have a unique structure and require full bottom surface support. Mount them directly onto the bottom of your deck, or else with stiff riser blocks between the trucks and the deck. Do not use rubber or urethane shock pads. These amplify stresses on the Baseplates – especially if the mounting bolts are over-tightened or tightened unevenly. Then relatively minor impacts can push the Baseplates past their breaking point.
G5 trucks will not fit through standard drop-through mounting holes, and they should not be drop-mounted to LDP bracket extensions. Unless stiff riser blocks are placed underneath the trucks, they should not be top-mounted on LDP brackets or on decks with drop-through mounting holes.
Axle Height, Axle Offset, and Roll Center
Axle Height: 59.5mm / 2.34 inches from baseplate bottom to axle midpoint
Axle Offset (Rake): 14.0mm / 0.55 inches
Roll Center: 16.2mm / 0.64 inches above axle midpoint
More Axle Offset (or Rake) pushes the Roll Center higher (towards the deck), resulting in quicker lean response and better wheel traction. Less Axle Offset (or Rake) leaves the Roll Center lower (near the axles), resulting in better lean control and stability.
