Features
- Forged from high-silicon aluminum alloy for maximum strength and dependability
- Wiseco offers a complete range of popular piston models and years for both trail and racing applications
- Durability, longevity and increased horsepower
- Innovative forging design and piston skirt provide maximum horsepower and torque
- Features forged pistons, rings, wrist pins, and circlips
- These high-tech piston designs offer maximum compression ratios, ultra-stiff strutted forgings, and titanium nitride-coated rings, which all add up to more power that is sustained longer
- Each piston is E-Coated on the crown, ring grooves, and pin bore, for maximum wear resistance and protection from micro-welding, galling, and detonation
- GP Series parts generally have less machining on the outside, which helps seal up the bore for increased compression
- Additionally, boost ports are removed for a more predictable powerband and increased pull on the top end
- Cylinder sleeves must be purchased separately.
- Service intervals may be increased with Racer's Choice pistons over conventional Wiseco pistons, and are for expert racers and tuners only.

Love it it was perfect for what I needed it for. Good quality!
Size: 4 Panel, Color: Black
It like a very dark chocolate brown/black. What I liked most about it is that you just pull it out of the box take the long plastic film off of it and it's ready to go. It has protective feet on the bottom. It's very attractive and it was so easy. It's so nice when you have a product you don't have to assemble.

Shipped quickly and as described
It was what I expected as functionality, lightweight and easy to move about. I plan to use it in my enclosed patio to obscure weight bench and wts. My only complaint is that the bamboo cover on one edge is not secure. But I will probably use a magic marker to cover the natural back that is showing. I don’t have time to return it as my event is coming soon.

Good product, needs double hinges for versatility.
Size: 6 Panel, Color: Brown
Blocks out all the light, looks good, good color. Only con is that it is not double hinged so it is hard to position the extra panels because I bout 6 panels instead of the 4 I usually get. Good deal, very decent price with the free delivery. Very clean packaging, came in great shape, no smell or odor from the factory.
