SIERRA Auto Tops & Seats - the value leader in replacement tops and seat covers

SIERRA Auto Tops & Seats

SIERRA Auto Tops & Seats is a direct to consumer brand of premium convertible tops, headliners, boot covers and selected seat kits for a large selection of American, European and Japanese made cars. Products are built to stock and ready to be shipped quickly around the world direct to the consumer.

To help ensure proper fit and finish, and protect the convertible owners investment, SIERRA recommends that their tops be installed by Professional Installers. Professional Installers have the tools, skills, adhesives, knowledge and experience to install these products correctly. Use the menu link above to Locate an Installer.

COMPUTERIZED CUTTING - SIERRA Auto Tops uses advanced Gerber Cutter cutting technology to design and cut its products.

FACTORY DESIGNS DUPLICATED AND IMPROVED - SIERRA Auto Tops duplicates factory designs, and improves upon them when necessary. They add reinforcements, use better heat sealing processes, and other manufacturing techniques; to produce high quality products.

HEAT SEALED REINFORCEMENTS - SIERRA Auto Tops heat seal its reinforcements in most of our products for extra strength and to prevent side to side shrinkage in tops. Heat sealed reinforcements will not bubble or fail over time as do most glued reinforcements.

GLASS WINDOWS - All SIERRA Auto Tops glass windows are manufactured using full width, first quality toppings. They heat seal glass into their tops and glass window assemblies using the same techniques as GM, Ford, Chrysler, Saab and other convertible manufacturers; and do not use inferior methods which produce weak bonds such as using silicone to install glass into window assemblies. They add reinforcements for extra strength when necessary, use all factory style extrusions and components, and carefully finish our glass window assemblies.

SIERRA Auto Tops offers clear, tinted and tinted with heater/defroster glass windows as convertibles were originally equipped. Their glass windows are made using tempered safety glass, and are marked AS-2 to show they meet all requirements of the National Traffic and Vehicle Safety Act, and the Federal Motor Vehicle Safety Standard, No. 205 (Glazing Materials CF MVSS 205).

PLASTIC WINDOWS - Like the tops and glass windows, SIERRA uses only full width, first quality toppings to manufacture our plastic window assemblies. The plastic / vinyl is a heavy gauge press polish for superior visibility and longest life.

Convertible Top Features

FINISH AND DETAIL - SIERRA Auto Tops purchases full width cloth and vinyl binding materials that are run to their specifications, to make most bindings they use to finish our tops and other products. Their bindings are more supple and sew on easily without bunching around tight curves on tops. Stitching in our products is held to a uniform length, and we do not ship products with broken or erratic stitches.

PRE-PUNCH BOLT HOLES AND ALIGNMENT GUIDES - SIERRA Auto Tops has added pre-punched bolt holes and alignment guide holes for precise fit and to speed installation in late model Chrysler, Mustang, and GM convertible tops and glass windows. For many other tops and window assemblies we show alignment guide holes for trimmers to correctly position top quarters and glass and plastic window assemblies.
