PART NUMBER: 61-2873
Includes four replacement pistons. Enough to rebuild one full 4 piston caliper.
Compatible with Dynalite 4 piston and Dynapro 4 piston calipers with 3.00in piston area, as used in our current Version 5 BBK (Dynapro 4) and our old Version 1 through 4 BBKs (Dynalite 4).
NOT compatible with any other calipers. Do not order this if you do not have the Wilwood DL4 or DP4 calipers.
Pistons fit great and were a perfect replacement for my dynalite calipers!
