GP80 Mk5 Fully Built Up Lower Housing
GP80 Series Winches can offer speeds of over 400ft per minute, down to 70ft per min and pulling power from 3 ton to 14 ton.
Whatever your application, there is a GP80 series winch for you.
Dominating competition podiums around the world, they have won almost every major title and in most cases on multiple occasions. A firm favourite with teams worldwide due to their exceptional performance and reliability.
As well as their competition pedigree they are equally at home in other applications and have found their way into many other commercial activities that require 100% reliability, speed and strength at all times.
If you have an application and you are unsure of your requirements, call or email us and we will happily advise you.
The GP80 MK5 Free spool lower housing has been designed, engineered & developed to provide the ultimate performance, speed & reliability demanded by the world’s toughest winch challenge competitions.
These winches are hand built to order and are made using the very best materials available.
The GP80 MK 5 is a complete Lower Gearbox housing fully built and only requires a Top housing, motors and solenoids.
Either a Warn single motor top housings or a Gigglepin Twinmotor Top Housing can be used on this housing.
The Winch Casings are cast from heat treated LM65 aluminium giving huge core strength without being excessively heavy. The Gear Set is designed by Gigglepin and engineered from Case Hardened EN36 steel, a superbly strong material that is used in the most expensive racing gearboxes and Differentials.
The Drum end plate also features a grease nipple and a purge bolt so that the free end bearing can be maintained with ease.
The brake is a Gigglepin designed billet unit using our own toughened brake pads and extra strong spring. This brake has been designed to take the rigours of Off-road motorsport without failing. Due to the brake being externally mounted, the GP80 series winches are ideal to use with synthetic cables such as Plasma (Gigglepin recommended), Marlow, Dyna-pull, Master pull, Bow rope and other brands as the winch drum never gets hot, unlike other winch models.
The Free-Spool is air operated and uses EN36 Case hardened dog technology that gives perfect ,fast operation every time. The winch is supplied with an IP67 waterproof toggle switch and a fighter pilot style switch guard. We recommend this is fitted inside the vehicle allowing the driver complete control of the winch at all times. Extra switches are available if required. The Free-Spool system operates using a standard ARB type air compressor as fitted to the majority of challenge/competition vehicles and can use air pressures from 50 to 150psi.
The winch drum is made in seven individual pieces and is end result of years of research and development.
Many companies make winches, but few understand the importance of this seemingly simple component.
The GP80 MK5 comes with a 13” (330mm) drum as standard (76mm longer than a standard Warn 8274), but can be specially ordered with shorter or longer drums (extra costs and lead times may apply). The drum has spaced 8mm end plates to help stop deflection and premature gearbox casing damage that can be experienced when using synthetic ropes.
The drum also uses a reduced diameter 64mm spool giving maximum mechanical advantage to the winch for greater power and allowing larger diameter or longer winch ropes to be used if required. Also fitted to the drum is the Gigglepin rope retention device, a simple to use loop on the drum that makes securing synthetic ropes fast and easy. The MK5 drum also has a removable EN36 hardened Dog receiver that is the bedrock of the air operated Free-spool. The drum is induction hardened at the gearbox end and ground to give a perfect running surface for the large bearings that give smooth and silky operation, finished in Gold Zinc for added corrosion resistance.
Every GP80 winch is serial numbered and is individual to each customer. They are also completely waterproof and shockproof.
