Boom Racing ProBuild 1.9" Ultra-Lightweight Wheels


Now Available! Two new ultra-lightweight ProBuild™ 1.9" offset wheels and include a new center lock ring design with a cleaner finish look.

Introducing the ultra-lightweight version of ProBuild 1.9" wheels in a 6-lug bolt pattern.

This lightweight ProBuild wheel is performance-oriented and designed to reduce weight and rotational mass.

The construction of wheel is designed to be durable and lightweight. The plastic barrels are machined from billet ABS blocks. The carbon fiber faceplate is inset which is designed to protect it from impact damages on the trails. The all-new barrel lip design helps the rig slide through rocks and whatever the terrain throws at it.

The performance-cut CNC machined Delrin center ring helps reduce rotational mass and maintains a strong structure to clamp the beads securely.

This lightweight ProBuild version has the same built-in offsets ProBuild is known for - four fully adjustable offsets built-in, and are interchangeable with all existing 1.9" ProBuild parts.

It can typically reduce up to 30-50 grams per wheel versus standard aluminum wheels.
