Description

When the weather is fair and the top is down nothing beats the joy of driving an Corvette convertible!  However, when the top is up, it's not so great. If the weather is too hot, too cold, too wet, or if you are on a long drive on the freeway, you just can't beat a Smooth Line Hardtop. Now you can have the best of both worlds!

​

Is your convertible top getting ragged, tired looking, ruining the appearance of your car, or worse yet, leaking?  It is time for the Smooth Line solution, the ULTIMATE REPLACEMENT CONVERTIBLE TOP.  Bring back the pride and joy of ownership of your ride! 

​

Adding a Smooth Line Hardtop is one of the best styling and practical improvements that can be made to your convertible. Coming or going, our custom designed Hardtop will give an exciting, clean, sleek appearance to your Corvette while protecting you from unwanted noise and weather

​

Our Removable Hardtop, which was introduced in the late 80's accents the C-4  roof silhouette. The profile and the style of the Smooth Line Hardtop is very similar to  the GM auxiliary hardtop, however, this is where the similarity ends.

 

The OEM's primary concept, which was successful, was to stiffen the chassis for racing purposes. The end result was very good looking, but not exactly user friendly for the average customer. It was heavy because of internal metal structure, noisy, difficult to install or remove, and did not fit all C-4 convertibles.  GM no longer supports any replacement  parts program for their hardtop.

​

On the other hand, the Smooth Line Hardtop is also very good looking featuring a flush mounted rear window for a very sleek and low look. Smooth Line's C-4 version is very user friendly, light weigh, only 35 pounds, yet strong, easy to install or remove and fits all years 1986 - 96. 
 

The interior is upholstered in a thick OEM felt automotive headliner material that will compliment the interior of your car. This headliner significantly absorbs road noises and also is an excellent insulator against heat or cold. Now you will be able to have normal conversation or really enjoy your favorite music on your stereo. Great on long drives!

Talk about quite, amazing!  See Corvette Enthusiast

​

Our rain guards will help keep your seats dry when the door is opened. This new Hardtop is complete with thick rubber moldings to ensure a weather tight seal. When your Corvette is parked or in storage, a Smooth Line Hardtop also adds additional security for the car and personal items.

​

All Smooth Line Hardtops are made in the USA by American craftsmen. Quality is an absolute !  All production is done in house to insure high standards. The shell is a premium grade automotive fiberglass composite which is very strong but light weight. The upgraded (extra cost) primed exterior is factory finished to perfection with two coats of smooth black urethane primer ready for a top coat color of your choice. For the best color match, we recommend using a local high quality auto body paint shop that can computer scan your Corvette to match the paint.

​

Every Smooth Line Hardtop is custom made to order by our expert trained craftsman, one at a time, and are assigned a unique serial number. 

​

The Smooth Line Corvette Hardtop is complete with headliner, rear window, seals & mounting hardware. Nothing extra to buy!

 

Coming or going, our Hardtop will give your Corvette a very aggressive stance that will definitely make heads turn! If you want the "Bad Boy"  look, this is it!
