For years, Wilwood has been telling us the day will come when billet 4 piston Dynalite calipers will be phased out. While we still have a few left in stock, available while supplies last on our Outlet page, billet 4 piston Dynalite calipers are no more. In it’s place is the Wilwood 4 Piston Forged Dynalite caliper, which serves as a direct replacement for it’s, now gone, billet brother. Now for the good and bad.

BAD: They’re simply not as bling as their billet brother. No way around that.

GOOD: The redesigned forged body is much stronger then it’s billet brother, so minimizing caliper flex and distrortion under heavy pressures is unquestionably better. In addition, this forged caliper is over 20% cheaper than it’s billet version.

So, the way we see it, that’s 1 bad vs 2 good, all in all things could be much worse. These Wilwood 4 Piston Forged Dynalite calipers are in-stock and ready to ship. Again, they serve as direct replacements for the billet version, so all existing Spider 9 caliper brackets still work.
