Honda TRX 450 Bottom End Kit - Hot Rods - `04-`05 is a complete bottom end rebuild package designed for 2004–2005 TRX450R/ER models. This kit gathers the essential components needed to replace the crank and lower engine seals, letting you rebuild the bottom end with one purchase.

The kit includes the crankshaft assembly, main bearings and seals, plus a full top and bottom end gasket set with all required seals. Using a single, matched kit reduces parts hunting and helps ensure fitment consistency during a rebuild. Hot Rods kits are known for matching tolerances and compatibility with factory components; a stroker crankshaft option is available on some models for those considering increased displacement as an upgrade path. Choosing a complete kit can save time compared to ordering individual parts and helps simplify the rebuild process for DIY mechanics and professional shops alike.
