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.

Mounting Advisory
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 extremely stiff riser blocks (preferably wood or even metal) 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.

    What can I say – these trucks are a work of art.

    I have an engineering background and a general appreciation for well engineered products, and these are light years ahead of any other truck I have seen and/or used.

    They are very precise, tune-able, and have none of the squishy feel of the bushing-style trucks I have seen or used. My son has the previous version of these on his board and they are also great. Nobody in our area has ever seen a Seismic truck, so they have a bit of novelty to them as well and people are curious what they are.

    Customer service from this company is exceptional as well. One of the small c-clips was broken upon arrival, and some spares were sent out to me immediately.

    I also purchased a set of 85mm Speed Vent wheels and Tekton bearings with these trucks, and all of the products from this company are excellent.

    The trucks are amazing. I’m running the 30* in back and the 45* up front. Installed them on my carving setup with purple springs on 30 and light blue on 45. After reading lots of forum posts on them, I decided to take the plunge. I wanted a more progressive lean that provided excellent feedback. My expectations were blown away. I’ve still got setups on bushings, but they are collecting dust. Carving is what I bought the trucks for and they deliver.

    A quick note about the customer service, because to me, this is what gains my loyalty. I had a question about my setup, which was answered in less then ten minutes by Dan himself. LESS THAN 10 MINUTES! His answer helped me dial in the setup that I wanted, and with the installation of some risers, I was on the street as soon as my package arrived.

    Seismic is a great product with great people behind it. They’ve made a loyal fan out of me and I bet they do the same for you.

    For carving these trucks are awesome. So responsive and the pump feel is great. I wasn’t sure which spring was best for me so i ordered an extra red (light) and green (medium) spring set to complement the blue (extra light) springs that came with my trucks. I tried these on two of my boards. Both are old school shape decks. One of the decks has a waterborne surf adapter. Trucks work great on both decks. I am 175 lbs. The green springs in the back and red springs up front felt best on the deck with surf adapter. The deck without surf adapter the extralight/light spring combo felt best. Only bad part is I like them so much. They make my independent and paris trucks feel like garbage. Now I have to buy another set so i can have them mounted on both boards.

    Anyone looking for amazing trucks, look no further! I have been usimg the Seismic spring trucks for about 7 years and they are still just as amazing as the day I got them with NO MAINTENANCE at all!!! I skate every chance I get and these trucks have outlasted at least 12 sets of bearings, 3 decks, and 5 sets of wheels! I am convinced these will be the last set of trucks I buy and they provide the best stability and turn radius I have ever used in the 21 years I have been skating. I cannot say enough good things about these trucks!
