PRODUCT DESCRIPTION

Fits: TF 727, A518, A618, 47RE & 48RE

727 high gear drum distortion and explosion testing simulates the event of sprag failure which can cause the front drum to increase in RPM by a factor of 2.2 times engine speed. Mancini Racing offers optional drums to deal with this for high performance applications.

This billet steel drum has been CNC machined from AIAI/SAE 1040-1045 Medium-Carbon Machinery Steel - NO Cast Iron used in this one!

•Stronger, more reliable and safer than the O.E.M. cast iron drum - Ideal for street use.

•Will hold up to 6 friction plates versus 4 in the O.E.M. unit.

•55% MORE Piston Apply Surface Area! This results in double the clamping force needed in third gear.

•Engineered with dual oil apply passages for even piston apply.

•Kit comes with a precision EXTRA-LARGE CNC machined billet aluminum piston.

•OPTIONAL Mancini Racing drum spring retainer & 15 springs. (#123900DSR)
