Full replacement Differential cup/case set for the HPI Baja (all models - 5B,5SC,SS,5T), This cup is the same dimensions as the stock HPI cup/case so is a direct replacement part. Diff cup/case is made from high grade 7075-T6 for the best weight to strength ratio and long life. Anodized in a clear finish comes complete with all internal parts shown (diff gear holders,Bush B080, bearing B030, O-rings, Seals, Hardened and ground drive pin (4x18mm), 2x shims and fixing screws (M4x16 BZP socket cap)). Please note, we recommend dry assemble of the diff first to check gear mesh & shimming for best fit and readjust if and where needed. The included 10x16x0.5mm shim is used to replace stock shim 87474. We have also included 4x special Oil filled bush to replace B080, these release oil over time to help lubricate the dirve cup shaft and give very long life. (we no longer supply the little bearings as an option due to them collapsing under the heavy load of modern high performance RC engines - bushes are just superior in all ways as time has proven) CompatibilityStock Gear box - YESTR Gear Box - YESIntegy Gear Box - YESHPI Stock Gear (HPI86480) - YESHPI HD Gear (HPI85481) - YESBlackbone ring gear - With Mods (inside gear fitment.)this is not a complete list and may work with unlisted items, this is what customers have let us know that work.
