Overall Assessment

Customers have roundly commended the product for its excellent fit, easy installation, and impressive quality. The material is routinely described as strong and durable, leading to increased performance and lifespan. Users greatly appreciated the extra clearance the product provided, specifically mentioning its practicality for header clearance in S10 454 installations. Some, however, reported issues with the bushings squeaking after some years of use. Overall, there was a high degree of customer satisfaction, with many claiming they would buy the product again and recommend it to others, noting its value for money and superiority over stock control arms.

I would highly recommend these arms for an S10 or Blazer.

Used these on my 2002 S10 Blazer, worked perfectly for getting it back to factory alignment specifications

Not real sure

I am somewhat confused as to the quality control of these arms. I received two of them, one had very tight tolerances of the bushings and the other very loose. After receiving two replacements I still have an arm with a rattling bushing and it was supposed to be hand picked from inventory. If they were advertised with loose bushings they wouldn't have been bought.

I've had these on an s10 for about 5 years and 20,000 miles. Bushings in these are all ready making very loud metallic squeaks everytime I go over a bump, close the door or get out of truck. Should've just bought stock control arms.

I am trying to use these arms (2 8" right side) on my 2000 Chevy S10. I ordered Ridetech ball joints for the S10 to use with them but they seem to be too small, not press fit. Are the G body ball joints different than the S series ball joints or are the arms way out of spec?

I want to use these on a 99 S10 that i am Doing an LS swap on with long tube headers. I read all kinds of conflicting information about whether I should use to 8 " arms or to 8.5" arms. I know these are typically not meant for street use but I am going to be using it on the street although not a lot. Right now I have one shim in the back and six shims in the front with factory control arms. Which arms do I need, the 8" arms or the 8.5" arms?

I am looking to replace my upper control arms on my on my 1993 2wd chevy V8 s10 with control arm #91031133-R and was wondering why people use 2 right arms? Also my left side control arm has about 3/8 of an inch shims in the rear of the control arm cross bar and about 1/8 shims in front of crossbar my right side upper control arm has about 1/16-1/8 on both front and rear of crossbar. Will using 2 rights even the shim situation on left side or is it just the way it has to be? Thanks....
