The standard bushing in the suspension of all Sprites and Midgets is made of rubber. When the factory decided they needed a little firmer feel they use a "metalastic" bush that is a rubber bush vulcanized to a metal bush. Modern engineered materials has now allowed a cost effective alternative. The use of "polyurethane" in a suspension bush provides a tremendous improvement in precision and control. The original use of rubber in the suspension is contrary to the design objective. Rubber was introduced as a compromise of handling in an attempt to broaden the appeal of the "sports car". This is no longer needed! "Poly" not only provides a great material to act as a pivot but the very low flexibility provides tremendous precision and control. The most commonly replaced bush in the front suspension is the top trunion bush. Two bushes are used to connect the top trunion to the shock. This bush not only serves as a critical pivot but also controls camber. Camber is the amount the wheel tilts in or out at the top. Typical high performance cars have "Negative" camber-the top of the tire leans inward. Worn bushes can also cause a change in "caster". "Caster" is the amount in degrees that the king pins of the front suspension tilt front to rear. Caster can effect a number of characteristics; the ease of turning the wheel, the tendency of the wheel to return to a straight ahead position, the camber while turning the wheel, etc. The important conclusion is that these simple bushes are very critical to the performance and handling of your Sprite or Midget. If you want to take some of the slop out of that front suspension then you have to take some of the rubber out of it. The shock arm is connected to the hub with rubber bushes; by replacing these with polyurethane you can still have a pivot bush without the slop.
Sold Individually, 4 required per car! Now available in two forms; direct poly replacement bushing (88G274/POLY) or "Poly-Adjustable" (88G274/P/ADJ) to allow for custom camber changes!

Question:
Do these bushings come with the metal sleeves that the fulcrum bolts go through. I did not see them in the photo with the bushings.
Answer:
These are poly bushes that upgrade from the 88G274 rubber bushes for the top trunnions. These don't have a sleeve but cushion the 2A4028 trunnion pin.
