The EP-1829A is an electronic distributor for Cadillac Escalade 5.7L and related Chevrolet V8 applications -- a variant configuration of the standard EP-1829. The 'A' suffix designates a connector or sensor configuration variant that serves a subset of GM 5.7L V8 applications where the standard EP-1829 configuration does not apply.
First-generation Cadillac Escalade (1999-2000) used the 5.7L Vortec V8 shared with the Chevrolet Tahoe and Suburban platforms. This engine uses the cast-aluminum housing Vortec distributor with an integrated cam position sensor. The EP-1829A replaces OEM 12570425 and 93441558, the primary OEM references for the Vortec 5.7L distributor in these Cadillac applications.
Verify the OEM part number on your existing distributor before ordering to confirm whether your application requires the EP-1829 or EP-1829A variant. Both cover Cadillac 5.7L V8 applications but with different connector and sensor configurations.
