A shock

Shock Absorbers:Lever Action Type

Lever action type shock absorbers were used on most cars until early 1950's and on some sports cars as late as 1980's (MGB, for example). Pistons in these shocks are connected to a shaft, one end of an arm (or a pair of arms) is attached to the shaft and the other end is connected to the suspension spring. Spring oscilation causes back and forth movement of one arm end, which on its other end induces rotary movement of the shaft, causing pistons to move and force the fluid through the valve ..., and spring oscillation is dampened. (Compare to modern "direct action" tubular shocks where piston and spring are attached to a single rod.) Rolls Royce SC2 rear shock

Two levels of shock rebuilding services:



  • Apple Hydraulics long standing reputation for precision workmanship started with these fine rebuilt shock absorbers.
  • Externally cleaned to bare metal. Housings rebushed with bronze bushings, shafts reground and polished. Cylinders and pistons are align honed and polished. To aid dirt and water exclusion highest quality double-lip seals are used, which outlast originals. Valving is properly calibrated for correct jounce and rebound specs. Painted with a gun-metal gray primer.
  • Prices listed are for Standard Rebuild.
  • Ever since introduction of our Heavy Duty shock line we have been selling them 2 to 1 over standard units.
  • Designed for our customers who enjoy driving their cars with performance in mind. Rebuilt to same high quality as our standard units with larger bronze bushing where main shaft rides. Shock valving is upgraded, 15% stiffer than standard shock. Highly recommended for many Armstrong aluminum body shocks, esp. Big Healey front, Midget/Sprite front and TR-6 rear shocks.
  • Please add $10 per shock for Heavy Duty Rebuild.
