Commercial truck aftermarket parts sales measure revenue from replacement parts and related aftermarket products for trucks and commercial vehicles.

PACCAR Parts reported $1.747B of sales in Q2 2026, up from $1.721B a year earlier.

Parts sales reflect volume, price, mix, and currency

PACCAR said Q2 parts volume declined while average selling prices and currency translation increased reported sales. A revenue increase therefore does not mean unit demand rose at the same rate.

Analyze sales with commercial truck aftermarket parts gross margin and commercial truck aftermarket parts pretax profit. Aftermarket parts can have different demand and margin behavior from new-truck manufacturing.
