Seismic Defcon Barrel Bushings Tall

Seismic Defcon Barrel Bushings Tall
Seismic’s Defcon ultra-high-rebound urethane has a remarkable set of unique and highly-advanced properties – and now we’ve applied it to bushings! Defcon is the fastest wheel formula in the history of skateboard racing – credited with virtually every significant world distance and speed record, including the official Guinness Standup mark. (Pete Connolly, 91.17 mph / 146.73 kph – Sept. 16, 2017, at The Top Speed Challenge in Quebec, Canada.)

A major step forward in bushing performance

• Deeper lean and truer, more fluid steering with less lateral hanger slop!
• Highly-energetic yet smooth and controlled return-to-center
• Larger compression range compared to other bushing formulas in the same duro – No premature packing • Fuller wheel contact (less “outside wheel lift”)
• Smoother, more linear resistance profile – Consistent feel • Advanced control

Fine-tuned dimensions for high-performance fit!

• Full 1.0-inch outer diameter optimizes seating in bushing pockets of finer modern hangers.
• Inner diameter carefully calibrated for snug fit on standard kingpin shafts.
• Mold-top ends precisely machined for exact height and superior flatness. – No warped end surfaces.
• Minimal radius on mold-bottom edges, and zero radius on mold-top edges. – Fuller contact with bushing seats and washers.

Precision-fit height: Tall
Tall 0.75-inch (19mm): Optimized fit both BS and RS in many modern race trucks. (e.g., Exile, Rogue, Ronin, Skoa, Valkyrie, Zealous, Dont Trip Boomer / DH-Cybin / Haki / Molly) Also fits BS in Caliber trucks if shim is removed.

Note: Defcon bushings may feel slightly softer than comparable duros from other brands using more basic urethane formulas. For optimal bushing performance, do not under-tighten or over-tighten kingpin nuts. Replace bushings that show signs of excessive wear, weathering, or aging.
