A complete bolt-in front suspension for 1963-1972 C10s. It replaces the factory crossmember with a tubular one carrying QA1 coilovers and power rack-and-pinion steering. Aimed at builders who want a big drop and modern steering on a classic C10.

Highlights:

  • Powder-coated tubular front crossmember with power rack-and-pinion steering
  • Three shock choices: Single Adjustable, Double Adjustable (18 clicks each of rebound and compression), 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
  • Bolts in with no frame cutting or welding. Made in the USA

Fitment notes: 1963-1972 Chevy C10 and GMC 1/2-ton 2WD trucks. Requires 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 52624 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. For small and big block Chevy engines, choose 7740-375 for 1963-1966 trucks or 7740-376 for 1967-1972 trucks, because 67-72 trucks use a different engine setback. The LS kit (7740-374) fits all 1963-1972 trucks. 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.
