The internals are why we can back it for two years.
Anyone can assemble an engine. We build ours with premium pistons and hardware most builders won't pay for, because that's what earns a 2-year warranty.
Dual-ring pistons
Better sealing and heat control under load.
Anodized crowns
A harder top surface that resists heat and detonation.
Skirt coatings
Reduced friction and a quicker, cleaner break-in.
Enhanced pin-oiling slots
More oil where the wrist pin works hardest.
Three cylinders.
Built by us.
We build vintage and mod triple engines under our own name — Sledwerx Built. That is a different motor from the OEM shortblocks we carry, built to order with our internals and backed by the same 2-year warranty.

Send us your engine. We'll supply the shortblock.
Ship us your engine and we'll set you up with a shortblock. If we don't have one in stock for your sled and you have a good core, we rebuild your engine right here to spec. Every motor comes back with a printed spec sheet and our 2-year warranty.
