KAD's own manufacture Steel Main Cap Set with 4 bolt centre main for the 1300 A-Series and 1300 A+ Mini Block.
Mandatory for any race A-Series engines where increased RPM is used. We have seen the standard caps move and chattering marks appear on the block and cap faces, this is when crankshaft breakages occur. The all steel main cap set has removed this inherent problem, they have been vigorously tested on KAD engines to withstand 9000+ RPM over 4 years of racing without any problems.
Special features on the KAD main caps are counterbored Allen sockets caps used. They are sunk into the main cap so no fettling of the gearbox case is required. Caps are also machined with both notches to except 'S' and A+ main bearings.
The complete cap set includes -
• All 3 steel main caps with 4 bolt centre
• High-grade Allen socket main bolts
• Main cap dowels
These caps suit 1300 A+ and GT blocks only.
Block will need line boring and the trust faces machining. KAD can provide this service if required, please call or email for more information.
