KSP PERFORMANCE sway bar bushing kit for pair — polyurethane M10/3/8in fit with enlarged washers & grease packet

A complete polyurethane sway bar bushing and washer kit designed to replace worn rubber grommets on a pair of stabilizer end links, restoring tight steering feel and longer service life.

This KSP PERFORMANCE aftermarket kit supplies everything needed to refurbish one pair of sway bar end links without replacing the entire assembly. Built from higher-durometer polyurethane with larger-diameter washers and a grease packet, the set addresses common rubber-bushing deterioration and lets you re-tighten link connections across many domestic trucks and cars. The components fit M10 or 3/8" threaded studs and are compatible with a wide range of OE-style and aftermarket link designs.

How will these polyurethane bushings change the driving feel?

Upgraded polyurethane provides a firmer, more consistent interface between the sway bar and lower control arm than aging rubber. You’ll notice reduced play in the end link and crisper roll control without replacing the whole link assembly.

• Stiffer material improves lateral control and reduces sloppy steering feedback.
• Larger washer surface spreads load to protect the bushing under torque.
• Grease packet lowers initial friction and helps prevent squeaks.

Will these fit my end links and vehicle models?

The kit was made to work with standard M10 or 3/8" threaded end link studs and the enlarged center bore accepts many aftermarket and OE-style links. Cross-reference OE and KSP part numbers if you’re unsure about exact fitment.

• Compatible with common factory and replacement end links using M10/3/8" studs.
• Includes multiple washers to match several link geometries and diameters.
• Contains KSP and OE part numbers for easier verification with vehicle parts lists.

What does the kit include and how do I install it?

The package gives you the bushings, washers and a small grease packet needed to service a pair of sway bar end links. Installation is straightforward: remove the worn rubber pieces, place the new polyurethane grommets on the stud, add the matching washers and tighten to the link’s specified torque.

• Package: 8 polyurethane bushings, 8 washers, 2 enlarged washers, 1 grease packet.
• Installation tip: apply the supplied grease to the bushing bore to ease assembly and reduce noise.
• Service scope: restores two end links (one complete pair).

How durable are these compared with original rubber bushings?

Polyurethane resists oil, road salts and heat better than standard rubber, which slows deterioration and helps maintain geometry under load. While firmer than rubber, they’re engineered to balance durability and vibration absorption for everyday and light performance driving.

• Higher-durometer PU resists flattening and deformation under repeated loads.
• Large washers reduce point loading that can shorten bushing life.
• Routine greasing extends service intervals and prevents squeak-related wear.

Who is this for: The KSP PERFORMANCE Universal Sway Bar Bushings & Washers Kit suits DIY mechanics, fleet technicians and enthusiasts who want a cost-effective way to refresh sway bar links without replacing entire assemblies. It’s ideal when rubber grommets are cracked or loose, for owners of domestic trucks and cars that use M10/3/8" end link studs, and for anyone wanting firmer suspension response with improved bushing longevity. Check fitment against your vehicle’s end link stud size and the listed part numbers before purchase.
