MW offers DTS Express / KTRE style bare housings. Both utilize 4130 tubes and can be assembled with your choice of housing ends. The housings are produced with the stock carrrier bore size (3.062"). For the builder who wants to fabricate the suspension mount in the car it makes sense to buy the bare housing. Due to the variety of options available, please collect your dimensions, know your suspension and how it will be mounted (4-link, leaf spring, ladder bar, etc.), then call 1-866-508-6394 or contact us to place your order.
