Crawford Essentials EJ257 Short Block — Better Than OEM

The replacement, done better than stock.

We start with a brand new, genuine Subaru OEM EJ257 short block (Part #10103AC870) and swap all the bearings for better bearings. Same factory block, crank, rods, and pistons. Stronger where stock is weak.

This is not a built motor. No forged internals, no power claims beyond stock. If you want power, buy a Crawford built block. If you need your car back, buy this.

• New genuine OEM short block, Part #10103AC870
• All bearings swapped for upgraded bearings, done by Crawford
• $3532.47 — the stock block with its weak point fixed, done by Crawford. Substantially less than a built block.
• Fits: WRX STI 2004–2021 (also EJ257 applications in Forester XT, Legacy GT, Outback XT — see the OEM EJ257 listing for the full fitment list).
• Do the job once: 2008–2021 EJ25 Short Block Installation Kit (kits for earlier years are listed separately).

Turnaround: Standard — the bearing swap is done in-house before it ships. Quick turnaround is the point of Essentials.

Expedited (+$500): Choose Expedited and it ships within one week, as long as the parts are in stock.

Shipping: Motors pay live carrier rates. No free shipping on motors.

Crawford Essentials is our budget-friendly line: replacement parts that are better than OEM. Built for drivers. Not focus groups.
