A complete bolt-in front suspension replacement for the squarebody C10. It swaps the factory crossmember, coil springs and steering box for a tubular crossmember, QA1 coilovers and power rack-and-pinion steering. Built for owners who want a big drop and sharper handling without cutting the frame.

Highlights:

  • Powder-coated tubular front crossmember with power rack-and-pinion steering
  • Three shock choices: Single Adjustable (18 clicks), Double Adjustable (separate rebound and compression, 18 clicks each), or MOD Series 4-way adjustable
  • 650, 750 or 850 lb/in coilover springs, with ride height set at the coilover
  • Up to 8 in. of front drop, depending on wheel and tire
  • About 140 lb lighter than the stock front suspension
  • Bolts in with no frame cutting or welding. Made in the USA

Fitment notes: 1973-1987 Chevy C10 and GMC C15/C1500 2WD trucks. Uses your 1973-1987 C10 spindles (not included). Inner fenders must be trimmed. For the best bump steer, run 18 in. or larger wheels: up to 6 in. backspacing on 18s and up to 7 in. on 20s. The steering shaft is not included. You may need different headers or an oil pan (stock SBC and BBC pans fit), and you may need new power steering hoses. Already running QA1 coilovers? See the 52625 Crossmember Retrofit Kit.

Engine mounts included: The QA1 crossmember needs its own engine mounts because stock mounts won't fit, so choose yours from the Engine Mounts menu. The bolt-in kits put the engine in the factory location, so the bellhousing and driveshaft stay put. The SB/BB Chevy kit (7740-375) is for small and big block Chevy engines, and the LS kit (7740-374) is for LS engines. The DIY weld-on kits (7740-378 for SBC/BBC, 7740-379 for LS/LT) let you weld up your own mounts for custom engine placement.

Lead time: Built to order by QA1. Typically ships in about 3-4 weeks.
