Great Product for Vehicles with Headers

I have to use a metal bearing upper control arm because my headers will melt polyurethane. I had ordered a pair of these originally from a guy on ebay for a ridiculous price. What he doesn't tell you is what length he will sell you. (They are the 8.0" version) For a 3" (2" Spindle, 1" spring) lowered street driven 2003 S10 2X4: If you use the 8.5" version (Left upper control arm) for both sides, you will have to use a lot of shims. Took a guy 2.5hrs to shim mine. If you use the 8.0" version (Right upper control arm) for both sides, you will be limited on how well they can put a true alignment on the truck due to the limited space. (No such thing as anti-shims :-) ) Love the fact that these are metal bearing. However, standard road driving will eventually tear these apart. My original set lasted about 2.5yrs (50k miles). Note: Remove the zerk fittings and put on 1/4" 90 degree zerk fittings. This will allow you to grease easily. I do recommend these. Enjoy!

Poor quality

I have received 2 of these arms so far and they both had loose pivots right out of the box. I'm currently awaiting a 3rd on in the hopes that it is tight enough to use.
