Product Details

The Callies BLTC125 is a high-performance connecting rod bolt designed specifically for use with Callies Compstar connecting rods. Featuring a 3/8 in. diameter and 1.255 in. underhead length, this bolt is precision-engineered to deliver consistent clamping force at the critical mating joint between the rod body and cap.

Key Features:

  • 3/8 in. diameter with 1.255 in. underhead length — sized specifically for compatible Callies Compstar rod applications
  • Manufactured from premium-grade alloy for superior tensile strength and clamping reliability
  • Designed to maintain dimensional consistency through repeated assembly and disassembly cycles
  • E-head style for positive torque application and accurate stretch measurement
  • Engineered to provide superior clamping force at the rod-to-cap mating joint
  • Sold individually — order the correct quantity for your application

Callies connecting rod bolts are the recommended fastener hardware for Compstar rod assemblies. Using the correct OEM-specified bolt ensures proper clamp load, dimensional repeatability, and reliable performance in high-horsepower and high-RPM engine builds. Always consult Callies' published torque and stretch specifications when installing rod bolts.

Really easy !

Shipping took longer than expected as I paid for expedited shipping. I reached out to ask why it wasn't sent two day and got no reply. The customer service could really use improvement and this is reflected in multiple reviews. However, the products arrived safely and as described. I'm very satisfied with the pricing as well. At the end of the day, that's the most important thing.

Fast, easy ordering. Products arrived within 9 days to WA. 98070

Fast shipping

Everything came in really quick and packed well. Apparently I just ordered the wrong part.

Easy purchase, came in a timely matter. Had came in two different days but still no problem.

Fast shipping. Great price on exactly what I was looking for

Bought wheels for a trailer, they arrived in a timely manner. The product picture was a little misleading but overall happy with the purchase.

So far so good Quick and easy to order
