Overall Assessment

Review summaries highlight the product's high quality, easy installation, effectiveness in lowering vehicles as advertised, and excellent fitting. Users report that the blocks are well-made, robust, and crafted from nice aluminum. The product's particular strength is its compatibility with various car models, offering a versatile solution. The perfect length I-bolts included received positive notes. However, some users note issues with u-bolt shapes and alignment pin sizes. This pushing aside, customers are generally satisfied, often noting the product improves their car's stance. Such attributes place the product a step ahead of its competitors.

Just right

Tech help always is welcomed and correct. This time lowering my '39 Chev coupe was somewhat of a puzzle as to how low to go. Tech got it right the first time...car looks great! Thanks Speedway folks.

Detail missing in add description

I ordered this lowering block kit for a 1956 Chevrolet. With the amount of parts supplied for tri-fives I didn't think I would have been an issue. When delivered the male/female alignment studs were 9/16" diameter instead of the 1/2" required for all tri-five cars. (Universal?) No where in the add did it list the actual alignment pin/bore sizes. Called customer service and shipped the kit back. But I'm still out the $9.00 in shipping to return this item.

For the price these are the way to go. Very sturdy. I will definitely be ordering these again. If you are getting these for the rear maybe consider shims to make sure the pinion angle is correct.
