The Splined Motor Pinion Gear has been redesigned by Gigglepin with an improved tooth design and manufactured from Billet EN36 before being case hardened. It's a huge step forward and allows Warn 8274/8074 users to have the quality and strength they need for the faster, more powerful modern DC motors with multi spline shafts.
May be required when fitting later replacement motors to early Warn 8274 winches.
