Hot Rods – Connecting Rod Kits, including kits for the 99-08 Honda TRX 400EX, the 2016 Polaris ACE 900 EPS plain bearing rod, the 04-05 ATP 500 4x4 and Hawkeye 400 HO, and the 02-03 Kawasaki KVF 650 Prairie. Each kit gives you the rod, wrist pin, big-end bearing and thrust washers matched to the original spec, or the plain bearing rod and bolt hardware that late-model four-strokes require. The connecting rod is the single hardest working piece in an ATV bottom end. It takes every combustion pulse and every abrupt throttle change on a rutted trail, and it is the part that fails first when a bottom end has been run hot, run low on oil, or spun past its limit. Fitting a fresh Hot Rods forged connecting rod with new bearings restores correct side clearance and radial play, so the crank runs true, vibration drops, and the engine pulls cleanly to the rev limiter instead of going flat. That means an ATV you can lug through mud, load with a rack of gear, and rev out on hardpack without listening for a knock. Tell us your year, model and displacement and we will confirm the correct rod kit fits before you order.
