Product Specs/Features/Expected HP Gains
- THE ONLY GEN1 DUAL BELT LIGHTWEIGHT CRANK PULLEY ON MARKET !!!
- Average Gains of 10-14whp due to it's light weight, reducing parasitic loss in the accessory drive
- 73% or 6lbs lighter then Stock Crank Pulley, weighing in at ONLY 2lbs 2oz !!!
- At only 2lbs 2oz its nearly as light as most UD pulley but with no charging issues!!
- SAFE to run PERIOD, even with light weight flywheel! -
The J-Engine is internally balanced, unlike an externally balanced engine such as an LS that use the pulley to counteract rotating harmonics. Anyone who states these are not safe to run are DEAD wrong, as we and MANY others have ran these for decades with ZERO ISSUES (currently on our 600hp TURBO J35 WITH a light weight fly wheel, 40k miles on this setup alone, along with all past NA and Nitrous Builds we had).
- Made in the USA from Extremely Resilient CnC'ed 6061 Billet Aluminum
- Machine Balanced to tight tolerances of just .25 of a Gram
- Drastic Increase of throttle response
- Stock Diameter (No charging issue as seen on Underdriven LW Pulleys)
- Retains the stock belt size, making it a 100% swap replacement. No second guessing what belt to run or search for a new one if something happens
- 1 Year HalferLand Performance Guarantee!!
Installation/Tips
It must be noted that our HalferLand Performance Dual Belt LW Crank Pulleys are machined to very, very tight tolerances, being our motors don't use what other motors do in traditional harmonic balancers (large amounts of rubber on crank pulley to absorb shock and harmonics, our cranks are finally balanced internally). As say a Cam pulley, these will be very tight to install and we recommend you.......
1.) lube the snout of the crank before installing the new pulley
2.) gently wiggle back and forth if it hangs up
3.) make sure you're installing the pulley directly on (very slight variations may cause it to hang up)
4.) And only if absolutely needed, you may use a rubber mallet to lightly tap it in.
The tight tolerances are in place to eliminate any play, which ultimately will lead to engine vibration down the road. In any case DO NOT REMOVE MATERIAL OFF THE PULLEY!!! If it gets hung up, refer to the steps above and try again. Removing material from the pulley can cause excessive play, which will only grow with time and could cause engine damage!!

- If the customer selected to have HalferLand Performance source/provide a core part(s) and chooses to cancel their order prior to shipping or starting the modifications/porting, a 20% part cost restocking/sourcing fee will be assessed from the credit/return. Example, the core part provided cost $100, a 20% Restock/Sourcing fee of $20 will be deducted from the credit of the order. This is due to our cost to source, purchase, clean the part and now the order being cancelled, we now are forced to sit on the part with direct order being associated with it or that we can use it for.
