The Wilwood Forged Dynalite serves as the base model in our Ultra4 performance large diameter brake setups. Forged Dynalites are the strongest calipers in the class, with weights lower than the competition. The process of stress-flow forging re-aligns the metals grain structure within the contour of the caliper body. This process eliminates the breaks and interruptions to the internal grain structure that occur when machining a straight block billet. Forged Dynalite calipers are a direct replacement for all Wilwood Dynalite and similar competitive brand calipers with 5.25" centered mounting lugs.
Spidertrax was founded in 1999 by two New Jersey guys who met each other in vocational school and who both were really into off-roading. Thomas Kingston is an mechanical engineer and Eddie Casanueva is a manufacturing engineer. Their engineering backgrounds combined with their love of off-roading is the key to Spidertrax innovative products. Eddie and Thomas custom produce mods for their own Jeeps. Then they run those mods up and down rock crawling trails until the mods fail. Then they meticulously examine the exact cause of the failure. They then incorporate a solution to the failure into the product design before starting mass production. The Jeep way of build-break-repeat is the very process that brings the quality to Spidertrax products. Shop Spidertrax Offroad Now
