Customers say

Customers praised the product for its easy installation, lightweight, and fitment. They noted its noticeable strength and solidity during use, particularly for S10 swaps needing additional clearance. The product's practicality by providing more room for headers and steering linkage was also highlighted. Buyers appreciated its lightweight construction, stating it is half the weight of a stock arm but stronger. The product was said to be of good quality, light, and sturdy. The product was further commended for helping users achieve their desired front-end setup easier. Many mentioned buying two rights for specific projects like drag racing and v8 swaps, stating this met their expectations. The control arms have been reviewed as a great fit, easy to install, offering more header clearance and being an excellent buy in term of value for money. The product was criticized by one customer for bending and breaking welds. The control arms were identified as beneficial for projects that necessitate greater clearance, particularly in exhaust manifolds. The recommendation was to buy two right sides for usage, especially when adding headers to a v8 S10. The product's deficiencies were noted in terms of workmanship and larger than necessary bolt holes on ball joints. Some commented that while it's not the highest quality, it's good value for the price and achieves its intended purpose.
