Description
P Series, 1/2 Groove, Choose Your Size, Tri Metal, Chevy, Big Block, Set of 5
P-Series bearings are built on steel backings with extra-thin overlays to prevent overlay fatigue. In addition, the oil grooves on most applications extend all the way around both halves for better oiling.

Clevite Fitment Guide
H Series -
- Best to start with when unsure which bearing to choose
- Medium level of eccentricity and high crush
- Enlarged chamfers for greater crankshaft fillet clearance
- Made without flash plating for better seating
- Use with crankshafts that have oversized fillets
- Use with engines that run mid-high RPM range
- Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface
P Series - - Typically the greatest level of eccentricity
- Rods and mains have high crush for maximum retention
- Most are fully grooved to maximize oil flow to rod bearings
- Reduced overlay thickness to prevent overlay fatigue
- Use where extremely high RPMs cause severe rod bore close-in
- Use where higher eccentricity is desired to narrow bearing contact patterns
V Series - - This series essentially duplicates Clevite's former Vandervell parts
- Typically low to medium eccentricity
- Not available with oversized chamfers
- No flash plating on the steel back
- All Clevite main bearing sets use a single-piece thrust bearing
- Narrowed parts available to accommodate increased crankshaft fillet clearance
- Lead-indium overlay offers slightly better conformability
M Series - - These are special purpose bearings having a nominal .005" thick Babbitt lining on a hardened steel back
- They are intended mainly for Blown Fuel engines where severe crankshaft deflections cause edge loading of the bearings
- Under these operating conditions bearing service life will be very short
- Frequent inspection and replacement is recommended
Part Number Key- H - High-Performance
- HD - High-Performance bearing with dowel hole
- HK - High-Performance bearing with moly/graphite coating
- P - Standard Clevite 77 tri-metal bearing
- M - Blown Fuel Engine bearing for severe crankshaft deflections & edge loading
- N - High-Performance Narrowed for greater crankshaft fillet clearance
- HG - High-Performance full angular grooved bearing
- V - High-Performance with Lead Indium overlay (On Main Sets this indicates partial groove also)
- VG - High-Performance with Lead Indium full angular grooved bearing
- D - Bearing has a dowel hole
- K - Tri-Armor coated bearing
- X - Bearing has .001 more oil clearance than standard
- XX - Bearing has .002 more oil clearance than standard
- A or AL - Indicates Aluminum bearing material
