FACTORY
ENGINE LOCATIONS
All K-members are not identical and the dimensions must
be checked to ensure proper fit of the headers or exhaust system. If the engine is not located correctly in
the chassis our products will not fit properly. If necessary place shims1
between the insulator assembly and the K-frame mounting pad to achieve
the proper factory dimensions.
1Shims:
For small position adjustments for header clearance
Shim Packs are available through Schumacher Creative
Services of Seattle, WA.
From the center of the crankshaft to the top of the
K-frame the correct distance is (A). The engine is also
offset
towards the passenger-side (B). Measure from the center of the crankshaft
to each frame rail, the difference should be (C).
