King Engine Bearings - Main Engine Bearing Kit - D17 Engine
HP Bearings | Applications | - High-load, short-duration racing such as drag racing, tractor pulls, monster trucks, etc.
- Medium-load, long-duration racing such as circle track engines using nodular cast iron crankshafts
|
| Construction | - Bi-metal aluminum silicon alloy featuring fine micro-bore finish
|
| Features | - 0.015" thick top layer for superior macro particle embedability and conformability
- 40 Vickers hardness to resist overlay migration and extrusion
- 450°F heat threshold for superior protection against friction and overheating
- Mains are 3/4 grooved for improved oiling to the rod journals
|
Our HP and XP lines are specifically engineered to withstand the highest loads and RPMs generated by today’s top competition engines. All King Performance Engine Bearings feature:
- “Bull’s Eye Tolerance”. King engine bearings have the closest wall tolerances in the industry, with all shells matched to 0.0001".
- Increased Height. Greater rod bearing height improves bearing-to-bore contact/heat transfer and reduces spin potential at high RPM.
- Improved Oiling. Mains feature enlarged, chamfered oil holes.
- Medium Eccentricity. This enables optimum load distribution and improved oiling.
- Dowel Holes. Most rod bearings are available with or without dowel holes.
- Narrowed Design. Mains and rods are narrowed for large-radius crankshafts.
