BPS Caterpillar C13 Head Bolt Kit 2421811 — KCB LEE

Fortify that C13 and send it back to work with the BPS Diesel C13 Head Bolt Kit!

The BPS Caterpillar C13 Head Bolt Kit is the complete stock replacement for C13 and C11 cylinder head installs — premium hardware built to hold clamp under heat, load, and long miles. Same idea as our C15 / C16 / ACERT head bolt kit: one box, every bolt and washer on the bench, ready to torque.

This kit gives you 26 long head bolts, 8 short head bolts, and 26 hardened washers. Long bolts are M16 x 2.00 x 220 mm class 12.9. Short bolts are M10 x 1.50 x 130 mm class 10.9. Hardened washers put the load where it belongs so the head stays sealed and the engine stays on the clock. Color-coded sleeves keep long and short bolts sorted for a clean, fast install.

Built for head gasket jobs, head swaps, and in-frame work on Caterpillar C13 and C11 engines. Install the kit, run the Cat torque-and-angle sequence, and put that iron back to making miles.
