These Caltracs are amazing, no way could these be destroyed especially with my 89 S10 running a 383 stroker. They are heavy which is needed at the backend of the truck. Just unpacked from shipping so I'm excited to started with the install. First impressions are well worth the cost. Just not worth having high HP if it's going to jump all over the asphalt. Speedway delivered quickly with a high quality product. Thank you so much.
