Redesigned to remove faults found with original unit that compromise strength and cause failures.

This is the same mainshaft that is used in our competition winning GP Series Winches.

Material grade has been increased from EN24 to EN36 to stop breakage.

Gears are now shimmed to support them, eliminating tooth breakage.

The circlip at the end of the shaft has been replaced with a cap and bolt configuration, ensuring correct brake function at all times.

The bearing surfaces have been manufactured to higher tolerances, giving unsurpassed reliability.

This mainshaft kit has been developed to give the serious Warn 8274 user the strength and reliability required in today's competition and extreme winch situations.

This kit has six advantages over the standard item:

Increased material strength.
Bolted end cap replaces brake end circlip.
Enlarged bearing surfaces to spread load evenly.
Deletion of retaining plate groove giving maximum shaft strength.
Shimming of gears reducing gear tooth breakage of the splined cams.
Redesigned, uprated cam gear for perfect cam engagement and greater strength.
The competition winch mainshaft kit is supplied with:

Small cam gear
Alloy "D" shim
Large circlip and spacer
2x M3 shim retaining bolts
End cap and bolt
