Monroe Shocks & Struts Suspension Shock Absorber P/N:34821
$61.99

Firm up the rear ride of your classic Ford hauler with the Monroe Gas-Magnum Suspension Shock Absorber 34821, a rear-position shock engineered for hardworking full-size trucks and vans. It fits the 1966-1969 Ford F-100 and the 1966-1977 Ford F-250 — see the Buyer's Guide tab for engine-level details.

  • Designed for trucks and vans: full-displaced valving on the compression cycle helps deliver controlled ride and handling for midsize and full-size trucks and vans.
  • Built to last: a heavy-duty nitrocarburized rod (on non-dust-shield units) and sintered iron piston enhance durability, while a self-lubricating fluid seal reduces friction against the piston rod.
  • Nitrogen gas-charge: helps maintain tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
  • Larger capacity: a bigger bore and 2-in. reserve tube hold up to twice the fluid of standard 1-in. bore shocks, so the shock works efficiently for a controlled ride and longer service life.

OE all-weather fluid carries special modifiers to handle extreme temperatures and reduce friction for smooth rod reaction. Backed by Monroe's Limited Lifetime Warranty and exclusive Feel the Difference Guarantee. Sold individually; replacing both rear shocks together as a matched pair is recommended for balanced handling.
