JZ Idler Pulley Lock - Series 1

JZ Idler Pulley Lock - Series 1
In stock

  If you're having trouble throwing the accessory drive belt on your JZ, it's probably due to the fact the idler pulley is on a spring that allows it to bounce. We've designed this Idler Pulley Lock to hold the tensioner pulley in place and eliminate the bounce.

  The lock mounts to the existing power steering bracket and idler pulley, so no need to modify anything or add any new brackets to the motor. You just replace two bolts with our stand off's then install your belt using the tensioner as normal so it sets the basic tension, then put the lock on with just a bit more tension. The lock is adjustable to suit a wide variety of belt lengths.

PS pump brace, PS Pump and belt not included

The tensioner is not a trunbuckle style double adjuster, this is intentional to keep from overtightening the belt.


Most JZ tensioners have a steel pulley with a bolt from the front to hold the pulley on and the arm itself is threaded, this lock will work with that style arm.

Some VVTi idler pulleys have a bolt and nut from the back that hold on the pulley to the arm, this tensioner is not designed to work with the that style tensioner. Typically these idlers have a plastic pulley. You will want the Sereis 2 lock, PN# T-JZ-IPL-S2.
